Every crane that we provide is specifically designed to suit the customer’s operations. For example, not all 10T crane quotes are the same. So specifying as much information about what you will use the crane for, the maximum load, lifting height, span, and more will help us you provide you with a more accurate crane quote and a faster response too.

What You Are Lifting?

What products you’re lifting and the shape of them may influence the decision of which crane is best for your business, and whether there is a need for a lifting or spreader beam. Lifting and spreader beams help to handle awkward loads in a balanced manner. Another example is wider products such as the image below of a client lifting large timber panels that required a claw-like addition to be able to lift safely and precisely.

 

The Maximum Weight Of The Load

The maximum weight of what you will be lifting is key. Weights may vary depending on the industry you’re in and what you’re lifting. But, in case of any future increases in weight, it’s better and important, to ensure your crane can safely handle the heaviest load and not the average. You can read more about crane weights and Safe Working Load (SWL) from our Crane Guides.

 

Lifting Height

The lifting height may determine whether single girder or double girder is required, which in turn may decide what hoist is necessary. Other considerations include the available floor space, are there any obstructions which would influence the lifting height? For example, is there other machinery in the area which would obstruct? If the crane is indoor, the height of the ceiling will also be a factor of how high the crane can lift

 

Span

The span is the distance between the crane’s runway beams. Knowing the approximate span is essential, as it determines the size of the crane and influences both its design and overall cost. A longer span generally requires a larger bridge structure and may affect the crane’s lifting capacity, supporting steelwork and installation requirements.

If you don’t know this exactly, then building drawings will help us to understand the span required.

 

Usage Frequency

The usage frequency of the crane may mean we recommend double girder to relieve the stress off one beam, or stronger systems may be required. For example, a 10T crane that is used once or twice a week will wear much less than a 10T crane that is used every hour of the working day, every week. Helping us to understand this can allow us to make a better judgement on the specifications required for your crane.

 

Indoor or Outdoor

The environment in which a crane operates plays an important role in its design. While the lifting capacity may remain the same, an outdoor crane could require additional features to ensure it can operate safely and reliably in changing weather conditions.

For example, in our 12.5T Goliath crane installation, the specification included travel warning beacons, storm anchors, wireless remote controls and an anti-collision system with long and cross travel buffers. These features were selected to suit the customer’s operating environment and improve both safety and reliability.

 

 

Building Structure

If your crane will be installed indoors, understanding the building itself is just as important as understanding what the crane will be lifting.

The size and construction of the building can influence the type of crane that is suitable and how it will be installed. Information such as the building width, available headroom, roof height and the location of existing machinery all help us determine the most appropriate crane solution. It can also help to understand the building foundations and whether it would with stand additional steelwork to support the crane.

 

Is It Replacing An Existing Crane?

If you’re replacing an existing crane rather than installing one in a new building, letting us know can help speed up the quotation process.

In many cases, an existing crane can provide valuable information about the current installation, including the lifting capacity, span, lifting height and runway arrangement. It also helps us understand whether the existing supporting structure may be suitable for a replacement crane or if modifications could be required.

It is helpful to tell us as much about the existing crane as possible. Why the crane is being replaced, for example due to age, increased lifting requirements, reliability issues or changes to production.

 

Don’t have all of this information?

That’s fine. This is just a guide as to what helps us provide you with a quicker and more accurate quote. If you have none of this information available and want a quote, that’s fine, get in touch! If you have some information, then great, tell us all about it and we’ll design a solution for your business. We manage every quote the same, whether it’s full of information or not, so don’t hesitate to get in touch today.

Crane prices are variable depending on a multitude of factors. The type of crane you choose whether than be an Overhead Crane, Gantry Crane, Goliath or Semi-Goliath Crane, or Swing Jib Crane is predominantly a huge factor in price. Larger cranes such as goliath cranes with a longer span and higher Safe Working Loads (SWL) will cost much more than a swing jib crane with a 500kg SWL for example.

There is no fixed price for a type of crane as each crane is designed specifically to an application. Other factors include additional steelwork, any changes to the building’s foundations, different hoists, single girder vs double girder and more.

Safe Working Load

Safe Working Load is the maximum load a crane can safely lift, carry, or lower under normal operating conditions. The SWL is set by the manufacturer and must never be exceeded during lifting operations.

SWLs vary depending on the type of crane and its intended application. A crane used to lift heavy steel fabrications in a manufacturing facility or large materials in a yard will require a much higher SWL than one used to lift small pallets or components during a production process. As the crane’s lifting capacity increases, so does the amount of steel, engineering, and supporting structure needed to safely handle the load. This typically results in a higher overall crane cost.

 

Span

The span is the distance between the crane’s runway beams. A longer span means the crane must bridge a wider gap, requiring larger and stronger steel girders to safely support the load. As more materials and engineering are needed, the overall cost of the crane increases. Span is an important factor for overhead, gantry, goliath and semi-goliath cranes. For swing jib cranes, the length of the jib arm is the equivalent factor affecting cost.

Lifting Height

A lot of the variables follow similar patterns where if there is a requirement for extra steelwork or any further specialised design. In the case of lifting height, a higher lifting height may require a different hoist selection, or design solutions to stool up the bridge girder as we did for this installation of 4x5T overhead gantry cranes. Further alterations may come in the form of building modifications to extend the height of the building. This will drive up the price much more compared to a different hoist selection and may require a 3^rd party.

Single Girder vs Double Girder

Single girder cranes typically cost less than double girder cranes. The simplest reason being that a single girder only uses one beam, whereas a double girder uses two so there’s less steel used. Single girders are used for lower lifting capacities in smaller overhead and gantry cranes whereas double girders are used for heavier lifting so naturally a more complex crane that is designed for heavier lifting will cost more.

Additionally, like other factors which influence the cost of a crane, the structural design is a big factor. In some cases, depending on workshop, bay space or the impact of the weight on the building or steelwork, both single and double girder solutions may work but the double girder solution may be recommended due to protecting the longevity of the crane by splitting the load across two girders rather than maxing a single one out.

Double girder solutions will likely also grant you extra lifting height as the hoist sits on top of the beams which may or may not be necessary in your case, it is business dependent.

 

Duty Classification/Usage Frequency

Frequency of use, also known as the crane’s duty classification, has a significant impact on cost. A crane used occasionally or one that does light lifting does not need to be built to the same specification as one operating continuously in a busy manufacturing facility that lifts heavy loads. Cranes designed for frequent or heavy-duty use require more robust components to withstand the increased workload, resulting in a higher overall cost.

For example, a single girder crane carrying heavy loads frequently is placed under greater structural stress than a double girder crane lifting the same load. A double girder design distributes the forces across two main girders, creating a stronger and more rigid structure that is better suited to heavier loads, longer spans and more demanding applications.

Crane that are used 24/7 or used heavily will also require more frequent inspections and servicing to ensure all the components of the crane are safe and operating how they are designed to be.

Installation and Transport

Installation and transport can have a significant impact on the overall cost of a crane. Larger cranes, such as goliath cranes with long girders, are more complex to transport and often require specialist haulage, lifting equipment and additional planning. Installation can also vary depending on the site, with factors such as access restrictions, additional steelwork, runway systems and building modifications all affecting the time and labour required. In comparison, smaller cranes such as swing jib cranes or lightweight gantry cranes are generally quicker and simpler to transport and install, helping to reduce overall project costs.

 

Future Costs

When budgeting for a crane, it’s important to consider the ongoing costs as well as the initial purchase price. Regular servicing and LOLER inspections are essential to keep the crane safe, reliable and compliant. Cranes that operate frequently or in demanding environments typically require more regular maintenance and inspections than those used only occasionally, resulting in higher long-term running costs.

How To Get an Accurate Crane Quote

The best way to get an accurate crane quote is to provide as much information as possible about your lifting requirements. This includes the type of materials you need to lift, the maximum Safe Working Load, whether the crane will be used indoors or outdoors, the available headroom, the required span and any other site-specific requirements.

Arranging a site visit allows our team to assess your premises, discuss your operational needs and determine whether there are multiple crane solutions that could suit your application. This helps us provide the most accurate quotation possible, allowing you to budget for your investment with confidence.

The more information you can provide, the more accurate and tailored your quote will be.

Overhead Cranes and Gantry Cranes are two of the most popular cranes in the industry and although they do a very similar job in terms of heavy industrial lifting, they do have their differences. It’s important to know the difference between an Overhead Crane and a Gantry Crane before choosing one for your operations. In many situations, it might be what you’re lifting, moving, and manufacturing which makes the choice of Overhead or Gantry for you. Your building structure and size will likely also play a part in that decision.

What is an Overhead Crane?

An Overhead Crane is a type of industrial lifting system used to lift, lower, and move heavy loads horizontally across a workspace. Overhead cranes are commonly installed in factories, workshops, warehouses, and manufacturing facilities where regular heavy lifting is required. The crane operates on elevated runway beams and uses a hoist and trolley system to transport loads safely and efficiently around the working area. Overhead cranes are designed to improve lifting safety, reduce manual handling, and increase productivity in industrial environments.

What is a Gantry Crane?

A gantry crane is a type of overhead lifting crane designed to move heavy loads across a working area. Depending on the application, gantry cranes can be fully supported by their own legs running on ground-mounted rails or be designed as overhead gantry cranes that operate on elevated runway beams within a building.

What are the main differences between an Overhead Crane and a Gantry Crane?

Operation

Overhead cranes operate on elevated runway beams inside a building structure. Gantry cranes are often mobile and are self-supported by their own legs and often don’t rely on building structure. However, in some cases, gantry cranes may run on wheels on elevated gantry steelwork and look similar to an overhead crane. The image below shows an example of this where the crane has been stooled up on the gantry steelwork to provide further lifting height.

Mobility and Floor Space

Overhead cranes a permanently fixed to the elevated runway and aren’t mobile. Due to the fact overhead cranes operate on elevated runway beams they leave the floor space free in your workshop. This allows space for other machinery, other cranes that can work in conjunction with overhead cranes such as swing jib cranes, and more space for your engineers/operators. Gantry cranes are more flexible as they can operate on wheels or rails to move to different locations in and around the working area. However, the legs and rails they operate from may prove difficult to work around in some instances, minimising floor space in your working area.

Installation and Environment

Overhead cranes will often require a longer design and installation process to ensure the existing building structure is strong enough to meet the weight of the crane itself, along with the added weight of the crane’s accessories and what it will be lifting. In most cases, at Harold Potter, we design a solution that meets the structural demands, added steelwork may be required. Overhead cranes are primarily designed for solutions that are indoors although they can be provided outdoors.

Gantry cranes on the other hand rarely need as long a process or changes to your building structure as they operate on wheels or rails mounted to the ground. They are self-supporting and handle the weight load of the crane beam, and what it’s lifting through its own legs, which are often designed in an A shape. Gantry cranes are found outdoor more often than overhead cranes due to the reliance of existing structure for overhead cranes.

Gantry cranes are applicable in both indoor and outdoor workplaces, however smaller gantry cranes that are designed for indoor use aren’t the best option for outdoor work. This is due to the added variable of the weather which will impact a crane’s performance and durability. It’s likely for heavy-duty outdoor lifting that standard indoor gantry cranes can’t handle, that a goliath crane will be advised. Goliath cranes are a much larger form of gantry that is specifically engineered to manage factors such as the wind and rain, while maintaining maximum safety.

Lifting Capacity

Overhead cranes on average will typically offer you a greater lifting capacity compared to a gantry crane. However, gantry cranes provide a wider range of lifting capacities if you include huge heavy-duty goliath cranes that can lift up to hundreds of tonnes. Both overhead and gantry cranes provide good lifting capabilities at common weights for businesses from 500kg to 10 tonnes, but overhead cranes are chosen more the heavier lifting in that weight bracket. Some of our recent case studies show examples of overhead cranes being used for 3.2T and 7.5T & 8T lifting.

Cost

The cost of overhead cranes and gantry cranes aren’t set in stone and are dependent on an abundance of factors ranging from the crane itself, the hoist, added steelwork, the span and wheels on the runways, and the foundations of your building. Crane costs are variable, but factors such as higher lifting capacity, single vs double girder and other variables requiring more materials will come with a higher cost.

Overhead vs Gantry Crane Summary

Both overhead and gantry cranes are top choices for businesses throughout the UK. There is no right or wrong on which is better, it just depends on which crane suits your business the best. The main difference between the two are the operation with overhead cranes relying on existing building structure, whereas gantry cranes are free-standing. Other differences are the mobility and floor space, along with the installation process with gantry cranes providing more mobility, overhead cranes providing more floor space and the installation process of an overhead crane is more likely to be longer due to potential of added steelwork to support the crane.

When an overhead crane breaks down, every hour of downtime can impact productivity, project schedules and revenue. One of the biggest challenges that businesses face is discovering that a critical crane spare part is on a long delivery lead time. In some cases, manufacturers may quote several weeks or even months before replacement crane parts become available.

So, what happens if your crane parts are on a long delivery and your business needs them urgently?

At Harold Potter, we hold extensive stocks of obsolete crane spares that can significantly reduce downtime when replacement parts are difficult to obtain.

Why Are Some Crane Parts Difficult to Obtain?

Many overhead cranes and lifting systems remain in operation for decades. While this demonstrates the durability of industrial lifting equipment, it can create challenges when crane spare parts eventually require replacement.

Some crane components become difficult to source because the original manufacturer no longer produces them. In other cases, the crane model itself may have been discontinued, or the component has become obsolete. Supply chain disruptions, overseas manufacturing and specialist electrical equipment can also increase delivery times.

At Harold Potter, we regularly help customers source replacement crane components that are no longer readily available through original manufacturers. Our extensive stock of crane spare parts and obsolete crane spares allows us to support equipment from a wide range of manufacturers.

What Should I Do If My Crane Needs Parts Urgently?

If your crane is out of service due to a failed component, the first step is to identify the exact crane part required.

At Harold Potter, we can often determine whether the required crane spare is available from stock, whether an equivalent component can be supplied, or whether an obsolete crane part can be sourced from our existing inventory. In some cases, refurbishment or upgrading to a modern replacement component may also be possible.

The sooner the issue is identified, the sooner replacement crane parts can be sourced and downtime reduced.

Can Obsolete Crane Parts Still Be Found?

Yes. Many obsolete crane spares can still be sourced even when the original manufacturer no longer supplies them. Over many years, we have built up a large inventory of discontinued crane parts. In many situations, sourcing a replacement part from stock can reduce downtime from several months to just a few days.

Do Harold Potter Stock Obsolete Crane Spares?

Yes. We stock a wide range of crane spare parts, replacement crane components and obsolete crane spares for many different crane manufacturers.

Through decades of crane design & manufacture, refurbishment and servicing, we have built an extensive inventory of crane parts that includes both current and discontinued components. This allows us to support customers operating older cranes as well as modern lifting equipment.

Our team regularly assists businesses that require urgent crane spares, hard-to-find crane components and replacement parts that are no longer supported by the original manufacturer.

What If My Crane Manufacturer No Longer Exists?

This is a common concern, particularly for older overhead cranes and hoists. Even if the original crane manufacturer no longer trades, replacement crane parts may still be available.

In many cases, equivalent components can be sourced or adapted to suit the existing equipment. Where original parts are completely unavailable, modern replacement systems or upgrades may provide a practical long-term solution.

How Can I Reduce Future Downtime?

Businesses can minimise crane downtime by taking a preventative approach to maintenance and spare parts management.

Routine crane servicing and planned preventative maintenance help identify ageing components before they fail. Regular inspections can also highlight parts approaching the end of their service life, allowing replacement crane spares to be sourced before they become a problem.

For critical lifting equipment, keeping key crane spare parts readily available can significantly reduce disruption should a failure occur. At Harold Potter, we can also advise on commonly replaced crane components that may be worth holding in stock.

Contact Us

If your crane is out of service and replacement parts are on a long delivery, we can help. Our experienced team can help identify hard-to-find crane parts, source suitable replacements and minimise costly downtime.

Contact our team today to discuss your crane spare parts requirements and get your lifting equipment back in operation as quickly as possible.

For many businesses, overhead cranes are an essential part of daily operations. Whether you’re lifting steel fabrications, machinery, tools, heavy materials or industrial equipment, a crane helps improve productivity, safety, and efficiency. If unexpectedly the power to your operations becomes faulty or goes out, you may find yourself asking some of these questions below:

What happens if our power goes out?

If your crane relies on electrical power for lifting and travel motions, a power failure can bring operations to a standstill. Fortunately, there are solutions available, including manually operated cranes and manual chain control systems that allow lifting equipment to continue functioning when electrical power is unavailable.

In these situations, businesses may experience delays in production and unexpected downtime. To reduce operational disruption, many organisations choose to install cranes that incorporate manual backup operation or use manual chain hoists as part of their lifting equipment strategy.

Can Overhead Cranes Operate Without Electricity?

Yes. While many modern overhead cranes are electrically powered, cranes can also be operated manually.

A manual overhead crane uses hand-operated chain systems to perform lifting and travelling movements. Instead of pressing buttons on a pendant control or wireless remote control, the operator pulls chains to move the load.

Manual cranes provide a simple and reliable lifting solution where electrical power is unavailable or unnecessary.

What Is a Manual Chain Hoist Crane?

A manual chain hoist crane uses a hand chain to raise and lower loads.

The operator pulls the chain, which drives a geared lifting mechanism inside the hoist. This allows heavy loads to be lifted with relatively little effort while maintaining excellent control. Manual chain hoists are commonly fitted to overhead cranes, gantry cranes, and jib cranes. Despite being manually operated, these systems can safely handle substantial lifting capacities when correctly specified.

How Does a Manual Overhead Crane Move Left and Right?

In addition to lifting and lowering loads, a manual crane can also move horizontally.

A manually operated trolley travels along the crane beam using a second chain. By pulling the second chain, the operator can move the load along the span of the crane without the need for electrical power.

Depending on the crane design, manual operation can include Manual hoist travel which moves the load left and right along the beam, manual bridge travel which moves the entire crane along the runway, and manual lifting which raises and lowers the load using a chain hoist.

Do Harold Potter Cranes Include Manual Operation?

At Harold Potter, we design and manufacture overhead cranes, gantry cranes, goliath, and semi-goliath cranes and lifting equipment to suit the exact requirements of each customer.

Most modern crane installations utilise electric hoists, and remote controls to maximise efficiency. However, we can also supply fully manual cranes or cranes with backup manual operation. Manual chain operation can provide an additional layer of flexibility and resilience for your lifting operation, in case of any unwanted disruptions.

Our team will assess factors such as lifting capacity, duty cycle, frequency of use, working environment and operational requirements before recommending the most suitable crane system.

Are Manual Cranes Still Used Today?

Absolutely.

Although electric overhead cranes are the preferred choice for many industrial environments, manual cranes remain widely used across the UK. Manual crane systems are particularly suitable when power may be inconsistent or not available, crane budgets are lower, and simplicity and reliability are prioritised.

For lighter-duty applications, a manual crane can provide an effective and economical lifting solution.

 

Frequently Asked Questions

Can a crane work without electricity?

Yes. Manual cranes and manual chain hoists are specifically designed to operate without electrical power.

What is a manual overhead crane?

A manual overhead crane is a crane that uses hand-operated chain mechanisms to lift, lower and move loads rather than electric motors.

What is a manual chain hoist?

A manual chain hoist is a lifting device that uses a hand chain and gearing system to raise and lower loads safely.

Are manual cranes safe?

Yes absolutely. When correctly specified, installed, maintained and operated, manual cranes provide a safe and reliable lifting solution.

Should I choose a manual or electric crane?

This depends on your lifting requirements. Electric cranes are generally best for frequent lifting and higher productivity, while manual cranes can be ideal for lighter-duty applications, remote locations or as a backup lifting solution.

Choosing the right crane for your business’ operations is vital and usually consists of variables such as the industry you’re in, what you need the crane for, and more. Buying a new or refurbished crane is a long-term business investment and it is key you fully understand your needs from the crane. That’s why this crane guide will breakdown the key factors in the decision-making process of purchasing a new crane.

Crane Capacity

The all-important question – how much weight do you need to lift?

Making sure this amount isn’t your average or isn’t too projected low is key, as it could lead to issues further down the line. This is an important step of the process. For example, if your business in the future requires a heavier lifting capacity, then it is less cost-effective to increase the lifting capacity of the crane after installation, than it is to opt for a crane that can handle heavier loads initially.

Businesses operating in smaller workshops may only need a lifting capacity of 500kg to 2 tonnes. Whereas, businesses operating in heavy industrial work, may need larger overhead or goliath cranes that have a capacity of up tens to hundreds of tonnes.

Overhead Travelling Cranes

Overhead travelling cranes are commonly used inside factories, engineering workshops and manufacturing facilities. These cranes run on elevated runway beams and provide lifting coverage across the workshop floor.

Single girder overhead cranes are typically suited to lighter lifting duties and smaller spans, while double girder cranes are often used for heavier capacities, increased hook height and more demanding workloads.

Goliath Cranes

Goliath cranes are commonly used outdoors or in areas where existing buildings cannot support an overhead crane system.

These cranes run on floor-mounted rails and are ideal for steel yards, depots, ports, heavy fabrication work. Semi-goliath cranes can also be used where one side of the crane is supported by the building structure and the other side runs on ground rails.

Swing Jib Cranes

Swing jib cranes are compact lifting solutions designed for smaller lifting tasks. They are commonly used at individual workstations, machine loading areas or workbenches.

Jib cranes are often installed alongside overhead cranes to improve lifting efficiency within specific sections of a workshop.

Crane Span and Lifting Height

Crane span refers to the width the crane must travel across, while lifting height determines how high the crane can safely lift materials.

Both factors are crucial during the crane design process. A larger span may require stronger crane girders, additional structural support and different crane configurations.

You should also consider available headroom, roof height, existing machinery, and potential future workshop layout changes. Maximising lifting height can significantly improve the usability of the crane, particularly in workshops where space is limited.

Indoor vs Outdoor Crane Installation

The working environment plays a major role in selecting the right crane system. Overhead cranes typically rely on existing building structure so would be an indoor system, whereas large goliath cranes that are free-standing would be found outdoors in yards and depots.

Indoor Crane Systems

Indoor cranes are usually integrated into the building structure or supported on dedicated crane steelwork. These systems are protected from weather conditions and are ideal for controlled production environments. Overhead cranes are preferred indoor to goliath cranes as they free up floor space as the rails/legs are not on the building floor. Therefore, this means there is more space for your staff, and any other small lifting systems like swing jibs which can coincide with overhead cranes.

Outdoor Crane Systems

Outdoor cranes must be designed to withstand environmental conditions such as weather and temperature changes. This is why goliath cranes are often preferred for outdoor applications, as they operate independently from the building structure. They also feature longer spans so can span across sites that may be longer than an existing building. They can also be dismantled ad move across sites giving more freedom than an overhead crane.

Can Your Building Support a Crane?

One of the most overlooked parts of the crane selection process is the building itself.

Not all workshops or industrial units can support an overhead crane without modifications. Structural considerations may include the strength of existing steelwork, column loadings, existing building foundations, runway beam support and roof structure limitations.

In some cases, additional crane supporting steelwork may need to be installed before the crane itself can be fitted. In other cases, the underlying building foundations may cause issues with being able to withstand the weight from adding a 10-tonne overhead crane for example. This is why a professional site inspection is essential before moving forward with a new installation.

New vs Refurbished Cranes

Depending on your budget and application, both new and refurbished cranes can offer benefits. A new crane allows for a completely bespoke solution designed around your exact operational requirements. Refurbished cranes can provide a more cost-effective option for businesses looking to improve lifting capabilities while reducing initial investment costs. The right choice will depend on your budget, required specification, and any future expansion plans.

Choosing The Right Crane Supplier

Selecting the right crane supplier is just as important as choosing the crane itself. An experienced crane manufacturer can help identify the best solution for your building, lifting requirements and future business growth.

At Harold Potter we design & manufacture, refurbish and install overhead cranes, goliath cranes, semi-goliath cranes and jib cranes for businesses across the UK. Our team works closely with customers to provide lifting solutions tailored to their operational requirements and working environments.

A Goliath crane, also known as a gantry crane, is a type of crane that runs on floor-level rails rather than elevated runway beams. The crane bridge is supported by steel legs which travel along a ground-mounted track system.

Goliath cranes are widely used in industrial environments where overhead runway support is not available or practical.

They are commonly found in fabrication facilities, shipyards, storage yards, and heavy manufacturing environments where large or heavy loads need to be moved safely and efficiently.

 

How Does a Goliath Crane Operate?

A Goliath crane works by moving a hoist and trolley system across a bridge beam while the entire crane travels along floor-mounted rails.

The hoist lifts and lowers the load vertically.

The trolley moves the load horizontally across the bridge beam.

The crane itself then travels along rails at ground level to move materials across the full working area.

This allows heavy loads to be positioned safely and accurately.

Goliath Crane vs Overhead Crane

The main difference between a Goliath crane and an overhead crane is the support structure.

An overhead crane runs on elevated runway beams connected to the building structure.

A Goliath crane is supported by its own steel legs which travel on rails installed at floor level.

Because Goliath cranes are self-supporting, they are often used outdoors or in locations where the building cannot support an overhead crane system.

What is the Difference Between a Goliath and a Semi-Goliath Crane?

A Semi-Goliath crane combines features of both an overhead crane and a Goliath crane.

One side of the crane runs on a floor-mounted support leg while the opposite side travels on an elevated runway attached to the building structure.

Semi-Goliath cranes are commonly used where floor space is limited or where only one side of the building can support a runway system.

They provide a practical lifting solution while reducing the amount of floor-mounted support required.

Typical Uses for Goliath Cranes

Goliath cranes are designed for lifting and transporting heavy materials across large industrial areas.

They are commonly used in manufacturing plants, steel facilities, outdoor heavy engineering environments.

They are particularly useful where lifting operations take place outdoors or where overhead structural support is unavailable.

Benefits of Using a Goliath Crane

One of the main advantages of a Goliath crane is that it does not require overhead building support.

This makes it suitable for outdoor lifting operations and large open working areas.

Goliath cranes can also cover wide spans and handle heavy-duty lifting applications efficiently.

Semi-Goliath cranes provide similar lifting performance while reducing the amount of ground-level support structure required.

Are Goliath Cranes Used Outdoors?

Yes. Goliath cranes are commonly installed outdoors because they are self-supporting and do not depend on a building structure for support.

They are often used in yards, loading areas, rail depots, and fabrication sites where large materials need to be lifted and transported outside.

Safe Working Load and Lifting Capacity

The Safe Working Load (SWL) is the maximum weight the crane can safely lift during normal operation.

The lifting capacity depends on the crane design, span, application, and operating conditions.

In the UK, Goliath cranes must be regularly inspected and maintained under LOLER regulations.

Most cranes require formal inspection every 12 months, although more frequent inspections may be required depending on usage and operating conditions.

Routine servicing and preventative maintenance help reduce downtime and maintain safe crane operation.

Summary

A Goliath crane is a self-supporting crane system that travels on floor-mounted rails. It is used to move heavy loads across industrial working areas.

Semi-Goliath cranes combine floor-mounted support with an elevated runway system to provide a flexible lifting solution where full overhead support is not practical.

Both crane types are widely used across manufacturing, engineering, heavy industry, and outdoor lifting environments because they provide safe and efficient material handling for large and heavy loads.

 

An overhead crane is a type of industrial lifting system used to lift, lower, and move heavy loads horizontally across a workspace. Overhead cranes are commonly installed in factories, workshops, warehouses, and manufacturing facilities where regular heavy lifting is required.

The crane operates on elevated runway beams and uses a hoist and trolley system to transport loads safely and efficiently around the working area.

Overhead cranes are designed to improve lifting safety, reduce manual handling, and increase productivity in industrial environments.

How Does an Overhead Crane Work?

An overhead crane works by moving a hoist along a horizontal bridge beam while the entire crane travels along runway rails.

The hoist lifts and lowers the load vertically using wire rope or chain.

The trolley moves the load side to side across the bridge.

The bridge itself travels along the runway system to move loads across the full working area.

This allows heavy materials to be lifted and transported safely with precise control.

What Are Overhead Cranes Used For?

Overhead cranes are used for lifting and moving heavy or awkward materials that would be difficult or unsafe to handle manually. They are commonly used in the industrial space. Industries such as manufacturing, engineering, workshops, steel industry, construction and other heavy-duty industries.

What Is the Difference Between a Single Girder and Double Girder Overhead Crane?

A single girder overhead crane uses one main bridge beam.

A double girder overhead crane uses two bridge beams for increased lifting capacity and higher hook height.

Single girder cranes are usually more cost effective for lighter lifting applications.

Double girder cranes are better suited to heavy-duty industrial lifting and larger spans.

The correct crane type depends on lifting requirements, building layout, and operational usage.

What Is the Safe Working Load of an Overhead Crane?

The Safe Working Load (SWL) is the maximum weight the crane can safely lift under normal operating conditions.

The SWL is determined by the manufacturer and must never be exceeded.

Operating above the Safe Working Load can create serious safety risks including structural damage, hoist failure, and dropped loads.

How Often Should Overhead Cranes Be Inspected?

In the UK, overhead cranes must be regularly inspected under LOLER regulations.

Most cranes require a formal inspection every 12 months.

More frequent inspections may be required every 6 months depending on crane usage and lifting conditions.

Routine servicing and preventative maintenance are also important for safe operation and reducing downtime.

What Causes Overhead Crane Failures?

Common causes of overhead crane failure include poor maintenance, worn structure or components, brake problems, electrical faults, and overloading.

Lack of regular inspection is one of the most common causes of crane safety issues.

Preventative maintenance helps identify faults before they become major operational or safety problems.

What Are the Advantages of an Overhead Crane?

Overhead cranes improve lifting efficiency and workplace safety by reducing the need for manual handling and forklift movement.

They also help maximise floor space because the crane operates above ground level.

Overhead cranes can safely move heavy loads with greater precision and control than many alternative lifting methods.

They are commonly used to improve workflow and reduce lifting-related downtime in industrial facilities.

Are Overhead Cranes a Legal Safety Responsibility?

Yes. Businesses operating overhead cranes in the UK must comply with LOLER and other workplace safety regulations.

Cranes must be properly maintained, inspected, and operated within their Safe Working Load limits.

Failure to maintain lifting equipment safely can result in legal liability, operational downtime, and serious safety risks.

Summary

An overhead crane is a lifting system designed to move heavy loads safely and efficiently across industrial workspaces. Overhead cranes are widely used across manufacturing, engineering, warehousing, and heavy industry because they improve lifting safety, increase productivity, and reduce handling risks. Understanding how overhead cranes work, how they are maintained, and how they are safely operated is essential for maintaining safe and efficient lifting operations. Following LOLER and SWL regulations is vital to keeping your operators and workplace safe.

SWL stands for Safe Working Load. It is the maximum load a crane or lifting device can safely lift, carry, or lower under normal operating conditions.

The SWL is set by the manufacturer and must never be exceeded during lifting operations.

Why Is SWL So Important?

SWL is one of the most important safety limits on any crane or lifting device.

Exceeding the Safe Working Load can lead to structural damage, crane instability, wire rope failure, brake failure, dropped loads, and serious workplace accidents. Following SWL limits helps ensure lifting operations remain safe and legally compliant.

How Is SWL Calculated?

The Safe Working Load is calculated by the manufacturer based on crane design, structural strength, lifting configuration, hoist capacity, stability limits, and safety factors. Engineers test cranes and lifting equipment to determine the maximum load they can safely handle during operation.

Where Is the SWL Displayed on a Crane?

The SWL should be clearly marked on the crane or lifting equipment. It is commonly displayed on the crane beam, near the hoist, on hooks or lifting attachments, and on identification plates or labels.

Under LOLER regulations, lifting equipment must clearly show its Safe Working Load.

What Happens If You Exceed the SWL?

Exceeding the Safe Working Load can create serious safety risks.

Overloading a crane may cause structural cracking, excessive stress on components, hoist or motor damage, tipping, instability, or lifting failure. Repeated overloading can also shorten crane lifespan and increase maintenance costs.

What Affects a Crane’s SWL?

Several factors can affect lifting capacity.

These include crane span, lifting height, load position, lifting angle, crane configuration, environmental conditions, and the condition of lifting components.

Some cranes may have different SWL limits depending on operating setup or attachment type.

Is SWL a Legal Requirement?

Yes. In the UK, lifting equipment must comply with LOLER regulations.

LOLER requires lifting equipment to operate within safe limits, display Safe Working Loads clearly, and remain properly maintained and inspected.

How Is SWL Checked During Inspections?

During inspections, engineers check identification markings, load rating plates, lifting accessories, hooks, hoists, structural integrity, and signs of overload damage.

Inspectors also verify that the crane is suitable for its intended lifting tasks.

SWL and Crane Safety

Understanding Safe Working Load is essential for safe lifting operations.

Correct load assessment helps prevent accidents, protect workers, reduce equipment damage, maintain compliance, and improve crane lifespan.

SWL should always be considered before any lifting operation begins.

Summary

SWL stands for Safe Working Load and refers to the maximum weight a crane or lifting device can safely handle. Operating within SWL limits is essential for maintaining safety, protecting equipment, and complying with UK lifting regulations.

All crane operators and businesses using lifting equipment should always understand and follow Safe Working Load limits.

What Does LOLER Stand For?

LOLER stands for Lifting Operations and Lifting Equipment Regulations 1998. It is part of UK workplace health and safety law.

Who Does LOLER Apply To?

LOLER applies to employers, site managers, crane operators, maintenance companies, construction firms, manufacturing facilities, and any business responsible for lifting equipment.

If a business owns, controls, or operates lifting equipment, it is legally responsible for compliance.

What Equipment Is Covered by LOLER?

LOLER applies to overhead cranes, gantry cranes, goliath and semi goliath cranes, jib cranes, lifting and spreading beams, hoists, shackles, hooks, forklift lifting attachments, and other lifting accessories.

In simple terms, if equipment is used to lift or lower a load, LOLER usually applies.

What Is Required for LOLER Compliance?

Equipment Must Be Safe to Use

Lifting operations must be properly planned and carried out safely using suitable equipment.

Equipment Must Be Regularly Inspected

Most lifting equipment must be inspected every 12 months. Equipment used for lifting people must usually be inspected every 6 months.

More frequent inspections may be required for heavily used equipment. For example if a crane is operation every day, all day.

Equipment Must Be Properly Maintained

Cranes and lifting equipment must be serviced regularly and repaired when faults or wear are identified.

Equipment Must Be Clearly Marked

Lifting equipment must display its Safe Working Load (SWL) and other relevant identification markings.

Inspection Records Must Be Kept

Businesses must keep inspection reports, maintenance records, and documentation showing compliance with LOLER regulations.

What Gets Checked During a LOLER Inspection?

A LOLER inspection checks the structural condition of the crane, lifting components, hooks, wire ropes, chains, brakes, electrical systems, controls, limit switches, and safety devices.

Inspectors also review maintenance history and compliance documentation.

What Causes a Crane to Fail a LOLER Inspection?

Common reasons include worn wire ropes, damaged hooks, brake problems, electrical faults, structural cracks, corrosion, overloaded components, and missing inspection records.

Even small defects can result in failure if safety is affected.

What Happens If You Fail a LOLER Inspection?

If a crane or lifting device fails inspection, it may be removed from service immediately until repairs are completed.

The equipment may require re-inspection before it can legally return to operation.

Serious safety issues can also result in enforcement action or insurance complications.

Who Is Responsible for LOLER Compliance?

Responsibility usually falls to the employer or business operating the lifting equipment.

In some cases, site managers or equipment owners may also share legal responsibility.

How Often Should LOLER Inspections Be Done?

Most lifting equipment requires inspection every 12 months.

Equipment used for lifting people normally requires inspection every 6 months.

More frequent inspections may be necessary depending on usage levels and operating conditions.

Why LOLER Compliance Matters

LOLER compliance helps reduce workplace accidents, improve safety, prevent equipment failure, and maintain legal compliance.

Regular inspections also help identify faults early before they become major safety risks or expensive repairs.

Summary

LOLER is the UK legal framework that ensures lifting equipment is safe, regularly inspected, and properly maintained.

Businesses using cranes or lifting equipment must comply with LOLER regulations to reduce risk, protect workers, and meet legal safety requirements.
