How Long Does an Overhead Crane Last?

As a general guide, a well-maintained overhead crane can often provide 20 to 30 years of service. However, there is no fixed expiry date for an overhead crane. Its actual lifespan depends on how frequently it is used, the loads it handles, its duty classification, the environment it operates in and how well it is maintained.

An older crane does not necessarily mean that it needs replacing. Many cranes can be repaired, refurbished or upgraded to extend their useful working life, provided the crane remains structurally sound and suitable for the work it is being asked to perform. However, in some cases a full replacement may be the better choice if your existing crane doesn’t have the latest technology or is slowing down your production.

What Determines How Long an Overhead Crane Will Last?

The lifespan of an overhead crane is affected by several factors, but two of the most important are how hard the crane is worked and how well it is maintained.

A crane that is only used occasionally to move relatively light loads will generally experience much less wear than an identical crane being used throughout a production shift to repeatedly lift loads close to its maximum capacity. The environment can also make a difference. Indoor vs outdoor cranes may face different conditions although cranes used outdoors are typically designed to deal with harsher circumstances. These conditions can accelerate wear and deterioration of mechanical, electrical and structural components.

The original design and specification of the crane are also important. A crane needs to be correctly specified for the work it is expected to carry out. This is where Crane Duty Classification becomes particularly important.

How Does Crane Duty Classification Affect Lifespan?

Crane duty classification describes how intensively a crane is designed to operate over its working life. It considers factors such as how frequently the crane operates and the loads it is expected to handle.

For example, a crane that lifts a load a few times a day has very different operating requirements from one that is used continuously on a busy production line. Both cranes could have the same Safe Working Load, but the crane used more intensively will require components designed to withstand a much greater number of operating cycles.

This is why choosing the correct duty classification when a crane is designed or purchased is so important. A crane that is correctly matched to its application should be capable of handling the expected workload without being unnecessarily over-specified.

If a crane is regularly operated beyond the conditions it was designed for, components can experience increased wear and fatigue. Over time, this can shorten the crane’s working life and increase the likelihood of breakdowns and expensive repairs.

Our Full Guide to UK Crane Duty Classification explains how FEM and ISO classifications work and why the duty rating of a crane is about much more than its lifting capacity.

Does Regular Crane Servicing Extend the Life of a Crane?

Yes, regular crane servicing is one of the most effective ways of helping to extend the working life of an overhead crane.

Like any mechanical equipment, crane components gradually wear during normal operation. Bearings, brakes, wheels, wire ropes, electrical components, gearboxes and other parts can all require attention over time. Regular servicing allows developing problems to be identified before they become more serious. A worn component can potentially be repaired or replaced before it causes further damage to other parts of the crane. For example, identifying a developing problem with a brake, gearbox or travel mechanism during a routine service may allow the issue to be dealt with as planned rather than resulting in an unexpected breakdown and significant production downtime. The frequency of servicing should reflect how the crane is used. A crane operating heavily every day may require more frequent servicing than one that is only used occasionally. At Harold Potter, some customers have their cranes serviced twice a year, while higher-use equipment may be serviced quarterly.

You can read more about how often an overhead crane should be serviced, what is included in a crane service and how servicing schedules can be tailored to the crane and its operating environment.

If you’re looking for reliable scheduled servicing which reduces downtime and extends the lifespan of your crane, you may want a crane service contract.

Do LOLER Inspections Extend the Life of an Overhead Crane?

A LOLER inspection is not the same as routine servicing, but it can play an important role in identifying deterioration and defects that could affect the crane.

Under LOLER, lifting equipment used at work must be thoroughly examined at appropriate intervals. In many cases this is every 6 or 12 months, although this is variable depending on the equipment and how it is used. A LOLER examination is intended to establish whether the lifting equipment remains safe to use. If defects or deterioration are identified, appropriate action can then be taken. Regular examination and servicing therefore work together. Servicing helps maintain the crane’s condition, while a thorough LOLER examination provides an independent assessment of its safety.

You can read our guide to LOLER inspections for more information about what is checked and how often inspections are required.

How Do You Know When an Overhead Crane Needs Replacing?

Age alone is not necessarily a reason to replace an overhead crane. A 25-year-old crane that has been well maintained and remains structurally sound may have plenty of useful life remaining, while a much newer crane that has been heavily used or poorly maintained may require significant repairs. The condition of the crane is therefore more important than simply looking at the number of years it has been in service. Signs that a crane may need significant refurbishment or replacement can include repeated breakdowns, excessive wear, structural damage or corrosion, outdated electrical equipment, difficulty sourcing replacement components and repair costs that are becoming uneconomical.

However, even when an older crane requires significant work, complete replacement is not always the only option. Depending on its condition, it may be possible to refurbish the crane, replace the hoist or electrical equipment, upgrade controls, repair mechanical components or source obsolete parts.

Our guide Should You Repair or Replace Your Crane? looks in more detail at the factors that should be considered before making that decision.

Can an Old Overhead Crane Be Refurbished?

Yes. Refurbishment can be a cost-effective way of extending the working life of an existing overhead crane. The exact work required will depend on the age and condition of the equipment. This could involve replacing worn mechanical components, upgrading electrical systems, repainting structural components or replacing obsolete controls and other parts. In some cases, a crane that has been in service for several decades can continue to provide reliable service following appropriate refurbishment. The important consideration is whether the existing crane structure and other major components remain suitable for the intended application. A competent assessment can help determine whether refurbishment makes sense or whether replacement would provide better long-term value.

How Long Does a Crane Hoist Last?

Overhead crane hoists typically have a lifespan of around 10 years. However, as with other components of a crane, more frequent use may lead to the hoist wearing out before the typical 10 year time frame. The expected working life depends on its duty classification, how frequently it operates, the loads it handles and the maintenance it receives. The hoist is one of the most heavily used parts of an overhead crane, so it can require attention or replacement before the main crane structure reaches the end of its useful life. This does not necessarily mean that the entire crane needs replacing. In some circumstances, replacing or refurbishing the hoist can allow the existing crane structure, runway and other components to continue operating for many more years.

How Long Will Your Overhead Crane Last?

There is no simple answer based purely on age. A crane’s working life is determined by how it was designed, how hard it has worked and how well it has been looked after.

Correct duty classification, regular servicing, thorough examinations and timely repairs can all help maximise the useful life of an overhead crane and reduce the likelihood of unexpected downtime.

If you have an older overhead crane you may be unsure whether it should be repaired, refurbished or replaced. Harold Potter can assess your existing equipment and discuss the most practical options for keeping it operating safely and reliably.

A Full Guide to UK Crane Duty Classification

Crane Duty Classification Explained: ISO/FEM, U, Q, M, S Ratings & %ED

When purchasing a new overhead crane, one of the most important technical specifications is its duty classification. While the crane’s Safe Working Load (SWL) tells you how much it can lift, the duty classification determines how often it can lift, how hard it can work, and how long it is expected to last.

Many people mistakenly assume that two 10-tonne cranes will perform identically. A 10-tonne crane used a few times each day is completely different from a 10-tonne crane operating continuously on a production line. Although both have the same lifting capacity, they require different components, different design considerations and significantly different budgets.

Understanding duty classification helps ensure the crane is correctly specified, avoids premature wear, reduces maintenance costs and complies with recognised engineering standards.

What is Duty Classification?

Duty classification is a method used to determine how demanding a crane’s working life will be. It considers factors such as how many lifting cycles the crane performs, how heavy the loads are, how often maximum loads are lifted, and the crane’s expected lifetime The operating environment

Rather than simply selecting a crane based on lifting capacity, manufacturers classify cranes according to how intensively they will be used.

Why is Duty Classification Important?

Selecting the correct duty classification affects almost every part of the crane. A higher duty classification crane may require larger gearboxes, more robust motors, higher specification brakes, better bearings, stronger wheels, more durable wire ropes, improved electrical components, and more frequent servicing. Although these components increase the purchase price, they are designed to withstand many millions more lifting cycles.

On the other hand, choosing a crane with too low a duty classification can lead to premature component wear, increased breakdowns, more expensive maintenance, reduced reliability, and shortened crane lifespan.

The Legal Framework: UK and European Law

In the UK and Europe, crane design is legally governed by strict standards. Your lifting equipment must comply with BS EN 13001 (for overall structural design) and ISO 4301-1 / FEM 1.001 (for lifting mechanisms). These will both be expanded on below.

Failing to install a crane rated for its actual working environment directly impacts your mandatory safety compliance. Cranes operating beyond their design limit run a high risk of failing their regular LOLER (Lifting Operations and Lifting Equipment Regulations) inspections and provide unnecessary risks to operators.

How Duty Classifications Are Calculated

The overarching duty group of a crane mechanism is called its M-Rating (M1 to M8). This rating is calculated by combining two distinct factors the U-Rating (Frequency) and the Q-Rating (Load Severity). In most cases for standard overhead cranes, M4-M5 is the typical M-rating.

What is a U-Rating? (Usage Frequency)

The U-Rating measures how often the crane operates. It categorises the total number of lifting cycles the crane is expected to perform across its entire design life. The U-ratings are as follows: U0 to U3 (Infrequent): Used occasionally for maintenance or standby tasks. U4 to U5 (Moderate): Standard use in warehouses or light assembly workshops. U6 to U7 (Heavy Use): Constant operation throughout daily factory shifts. U8 to U9 (Continuous): Round-the-clock, non-stop severe industrial work.

What is a Q-Rating? (Load Weight)

The Q-Rating measures how heavy the loads are relative to the crane’s maximum capacity (SWL). The Q-ratings are as follows: Q1 (light loads): The crane rarely lifts its maximum capacity; it mostly moves light loads. Q2 (moderate loads): Regularly lifts medium loads, occasionally hitting maximum capacity. Q3 (heavy loads): Frequently lifts loads close to the maximum safe working limit. Q4 (maximum loads): Constantly lifts loads at or very near its maximum SWL.

The M-Rating (U + Q = M)

By crossing your frequency (U) with your load severity (Q), you find your required M-Rating.

Note: While international standards technically define ultra-light M1 and M2 classes, Harold Potter and most leading industrial suppliers start standard ranges at M3.

Load Spectrum Class (Q) Infrequent Use (U0 to U3) Moderate Use (U4 to U5) Heavy Use (U6 to U7) Continuous Use (U8 to U9)
Q1 – Light Loads (Rarely lifts full capacity) M1 to M3 M4 M5 M6
Q2 – Moderate Loads (Sometimes lifts full capacity) M1 to M3 M5 M6 M7
Q3 – Heavy Loads (Frequently lifts full capacity) M1 to M4 M6 M7 M8
Q4 – Very Heavy (Consistently lifts maximum capacity) M2 to M5 M7 M8 M8

Table 1 – Identifying the M-Rating

FEM Classification vs ISO Classification

FEM stands for Fédération Européenne de la Manutention (the European Materials Handling Federation), and ISO stands for the International Organisation for Standardisation. Both organisations have created classification ratings for cranes dependent duty cycles, workload, and the lifespan of the crane. The main difference is age and origin: FEM is the traditional European standard heavily favoured by classic manufacturers like Demag or Konecranes, while ISO is the universally adopted global framework. The ratings can be corresponded to one another. For example, as seen in the table below, FEM 1Am is identical to ISO M4.

FEM Classification ISO Equivalent Rating Typical Duty Level
FEM 1Dm M1 Standby / Extremely Light
FEM 1Cm M2 Very Light / Maintenance
FEM 1Bm M3 Light Workshop Duty
FEM 1Am M4 Standard General Engineering
FEM 2m M5 Medium / Heavy Production
FEM 3m M6 Heavy Duty / Continuous Fabrication
FEM 4m M7 Severe Duty & Steel Yards
FEM 5m M8 Continuous Maximum Duty

Table 2 – FEM Classification & ISO Equivalent

What Does an M-Rating Actually Mean?

The M-Rating only refers to the mechanical components of the crane. Components such as hoists, brakes, wire ropes, motors, gearboxes, and wheels are all part of the M-Rating. A higher M-Rating means these components are designed to withstand significantly more lifting cycles through their lifespan.

It’s important to clarify that a higher M-Rating DOES NOT mean the crane can lift more and has a higher Safe Working Load. For example, a 5T M3 rated crane and a 5T M6 rated crane both can lift the same amount, but the M6 crane has components that are designed for more frequent use and a longer lifespan.

The Electrical Counterpart: What is ED%?

ED% (Cyclic Duration Factor) measures the exact percentage of time a crane’s motor can actively run under load within a standard 10-minute period before it must stop to rest and cool down. For example, a crane with an M5 rating typically features a 40% ED motor, meaning it can safely operate for 4 minutes but must rest for 6 minutes to prevent overheating.

ISO Rating FEM Rating Motor Duty Factor (% ED) Max Work Time (Per 10-Mins) Min Rest Time (Per 10-Mins)
M3 1Bm 25% ED 2.5 mins 7.5 mins
M4 1Am 30% ED 3.0 mins 7.0 mins
M5 2m 40% ED 4.0 mins 6.0 mins
M6 3m 50% ED 5.0 mins 5.0 mins
M7 / M8 4m / 5m 60% to 100% ED 6.0 to 10.0 mins 4.0 to 0 mins

Table 3 – The ISO, FEM, and Motor Duty Factor (%ED) table – starts at ISO rating M3*

What is an S-Rating? (Steel Structure Rating/Classification)

While the M-Rating describes the crane’s mechanical parts, the S-Rating applies to the steel structure of the crane.

An S-rating ranges from S0 to S9. It outlines exactly how much structural fatigue and stress the crane’s main bridge girders, end carriages, and steelwork can safely withstand over their operational lifespan. It follows the same pattern as the other ratings whereby S0 is for very light and non-frequent lifting, and S9 is for extremely heavy-duty loads with continuous lifting.

Does a Higher Duty Classification Cost More?

Yes. A higher duty classification costs more in upfront costs, but if you identify the correct duty classification for your business, it will save you money long-term.

As you progress through from standard cranes (M4) up to higher duty cranes (M6+), it’s very likely the crane will need stronger mechanical components and a stronger steel structure to be able to withstand the added frequency of lifting.

Choosing the Right Duty Classification

Selecting the perfect duty classification comes down to a balance: under-specifying creates severe safety hazards and costly breakdowns, while over-specifying means you are paying for an oversized steel structure and heavy machinery that your facility simply doesn’t need.

To determine exactly what classification your project requires, you should confirm these 3 questions below:

What is the Safe Working Load?

What is the absolute maximum weight the crane will ever need to lift?

How often will the crane be lifting? (Usage Frequency – U rating)

Over a standard shift, how many total lift cycles will the crane perform? For example, is the crane used a few times a week, or 30 times an hour on a production line?

What is the typical weight distribution? (Load Weight – Q rating)

When the crane is operating, are most of your lifts at the absolute maximum capacity, or are you usually lifting much lighter loads?

You can refer to Table 1, Table 2, and Table 3 above to align your business’ operations to its correct duty classification. If you’re unsure contact our team today and we will specify the correct crane for your business.

How Much Does a 5T Overhead Crane Cost?

One of the first questions businesses ask when considering a new overhead crane is, “How much will it cost?”

The honest answer is that there isn’t a fixed price. Every overhead crane is designed around the building it will operate in, and the lifting requirements of the business, meaning no two projects are the same.

However, we also understand that when you’re planning a project or preparing a budget, you need a realistic figure to work from. That’s why we’ve created this guide.

As a general guide, a standard 5 tonne overhead crane with a 13.5 metre span and 4.5 metre lifting height would typically cost around £55,000. Depending on your exact specification and site requirements, the final price could vary by approximately by +/-10%, but this provides a reliable starting point for budgeting.

Throughout this guide, we’ll explain what contributes to that cost and why some cranes are more expensive than others. Factors such as the crane’s span, the type of runway system it operates on, installation requirements and site conditions all influence the final price.

Span

Span has one of the biggest influences on the overall cost of an overhead crane. As the span increases, the crane bridge must be manufactured from larger and stronger steel sections to safely support both its own weight and the load it is lifting. This means more material is required, along with additional fabrication, machining and manufacturing time.

For example, a 5-tonne overhead crane with a 13.5 metre span, like our example, will generally cost less than an equivalent crane with a 20 metre span because considerably more steel is needed to achieve the greater width while maintaining the required strength and rigidity.

Longer spans can also increase transport and installation costs, particularly where larger components or specialist lifting equipment are required on site.

Lifting Height

The lifting height is the maximum distance the hook can safely travel vertically, from its lowest position to its highest.

In many cases, increasing the lifting height has a smaller impact on price than increasing the crane’s span, but it is still an important consideration. A greater lifting height typically requires a longer wire rope or chain, a different hoist configuration and, in some applications, additional engineering to ensure the crane operates safely and efficiently.

Choosing the correct lifting height is important. Specifying more lift than you actually need can increase the project cost unnecessarily, while insufficient lifting height may prevent the crane from carrying out its intended task effectively. Selecting a lifting height that matches your application helps ensure you achieve the best balance between performance and cost.

 

Gantry Steelwork

Gantry steelwork is a major factor in the overall cost of a crane. For example, if a crane requires an 18 metre long gantry with four upright legs on each side, spaced 6-metres apart, a significant amount of structural steel is needed. The additional material increases both the weight and the overall cost of the crane. It’s essential to provide stability for the crane so that it can safely bare the load of the crane and what is lifted.

On the other hand, a crane installed on an extension attached to an existing building is often more cost-effective than a free-standing gantry, as less supporting steelwork is required. However, if your premises are rented rather than owned, modifying the building may not be possible without the landlord’s approval, making a free-standing structure the more practical solution despite the higher cost.

Duty Classification

A crane’s duty classification describes how often it will be used and how demanding the lifting application is. This is an important factor when determining the overall cost of a new overhead crane.

For example, a 5 tonne crane used a few times each week for occasional maintenance work does not need to be built to the same specification as a 5 tonne crane operating continuously every day of the week. Although both cranes have the same lifting capacity, the components of both cranes may be very different. Cranes with a higher duty classification may require more expensive components such as larger motors, different hoists, and stronger steel to withstand the extra use.

See our full guide for Crane Duty Classification for more information.

Other Factors

While the crane’s span, lifting height, and steelwork are some of the biggest factors affecting price, there are several other considerations that can influence the overall project cost.

Transport is one of these. Larger cranes require longer steel sections and heavier components, which may need specialist transport or multiple deliveries to site. The further the installation location is from the manufacturing facility, the greater the transport costs are likely to be.

Site access can also have an impact. If the installation area is easy to access with good space for lifting equipment and deliveries, installation is generally more straightforward. However, sites with restricted access, low headroom, and confined working areas can make the installation more complex. In these situations, additional planning, specialist lifting equipment or phased installations may be required, increasing the overall project cost.

Labour costs vary depending on the complexity of the installation. A simple installation in an empty building can often be completed more quickly than a project where engineers must work around existing machinery, production schedules or restricted working hours. Weekend work, night shifts or planned shutdowns can also affect the overall labour cost.

Although these factors typically have a smaller impact on the overall price than the crane’s specification, they are still considered when preparing a quotation. Every installation is different, which is why a site visit is often carried out before a final price is provided. This ensures the quotation accurately reflects the work involved and avoids unexpected costs later in the project.

3.2T Crane vs 5T Crane

3.2T cranes and 5T cranes are widely recognised in the industry as the baseline for overhead cranes. Components of the crane such as the end carriages, panels, and hoist would be the same price for a 3.2T crane and a 5T crane. The main difference in price between the two again comes from the span and steelwork. Simply, the more steel required, the higher the cost. Although, the overall cost of a 3.2T crane wouldn’t be too dissimilar to a 5T crane.

Summary

As a guide, a standard 5 tonne overhead crane with a 13.5 metre span and 4.5 metre lifting height typically costs around £55,000. Depending on the exact specification and site requirements, the final price can vary by approximately 10% either way.

As we’ve covered throughout this guide, the biggest factors affecting the overall cost are the crane’s span, lifting height and the type of supporting structure it runs on. Additional considerations such as transport, site access and installation labour can also influence the final quotation.

Every crane is designed to suit its intended application, which is why no two projects are the same. While this guide provides a realistic benchmark for budgeting, the best way to receive an accurate price is to discuss your requirements with our team. We can advise on the most suitable crane for your application and provide a quotation tailored to your building, lifting requirements and operational needs.

Again, we re-iterate this is a guide price and price may vary.

Crane Load Test – FP McCann Byley

A crane load test was carried out on the A and B outdoor gantry extensions prior to handover for our friends at FP McCann, Byley. The completed extensions allow the client to move finished products directly into the storage area without the need for trailers.

Each of the four cranes was load tested using specific weights corresponding to its individual Safe Working Load (SWL). The cranes were: 1x25T, 1x16T, 1x15T, and 1x10T.

During testing, all deflections of the crane bridge beams and gantry steelwork were measured and confirmed to be within the regulated tolerances.

The gantry extensions intersect with the existing Goliath crane pathway. To ensure safe operation and prevent any possibility of collision with the current Goliath cranes, the new installation has been fitted with multiple electronic limit switches and distance sensors.

What is a Crane Load Test?

 

A crane load test is a process used to verify that a crane is structurally capable of safely carrying its rated Safe Working Load (SWL). Depending on the purpose of the test and the applicable standards, the crane may be tested using a certified proof load that exceeds its normal rated capacity. During the test, the crane lifts a certified test weight under carefully monitored conditions to ensure it performs as expected and that all critical components are operating correctly. Typical industry standards are 110% of the cranes’ SWL is tested for dynamic load testing and 125% for static load testing.

Load testing is an important part of installing new cranes, returning equipment to service after major repairs, and verifying that lifting equipment continues to meet the required safety standards. While a crane may appear to be working normally during everyday use, a load test provides additional confidence that it can safely operate at its full rated capacity.

Cranes are responsible for lifting valuable materials and heavy loads, it is essential that they are tested correctly before being relied upon in the workplace.

Why Is Crane Load Testing Necessary?

Crane load testing helps ensure that lifting equipment is safe, reliable and fit for purpose before it is put into operation. It verifies that the crane can safely lift its maximum rated load without compromising its structural integrity or the performance of its mechanical and electrical components.

During a load test, engineers can assess how the crane behaves under load, checking that the hoist lifts smoothly, the brakes hold securely and the crane travels correctly along its runway where applicable. Any unusual movement, excessive deflection or mechanical issues can be identified before they become a safety risk during normal operation.

Load testing also provides reassurance to crane owners, operators and site managers that the equipment has been thoroughly assessed and is ready for service. In many situations, it forms part of demonstrating compliance with relevant legislation and industry standards.

How Is a Crane Load Test Carried Out?

Before any weight is lifted, engineers carry out a thorough inspection of the crane to ensure it is in suitable condition for testing. This includes checking the hoist, wire rope or chain, end carriages, controls, brakes, electrical systems and any visible structural components.

Once these inspections have been completed, certified test weights are positioned beneath the crane. The crane then lifts the load in a controlled manner while engineers carefully monitor its performance throughout the test. Testing methods such as steel, water bags or specially designed concrete weights are common test weights. Whatever method is used, the weight must be accurately known to ensure the test is carried out safely and correctly.

Depending on the type of crane and the testing requirements, the crane may also travel along its runway, move the trolley across the bridge or perform several lifting cycles while under load. Throughout the process, engineers observe how the crane responds, ensuring movements remain smooth and that all safety devices function correctly.

After the load has been safely lowered, the crane undergoes a final inspection before the results are recorded and any required certification is completed.

How Long Does a Crane Load Test Take?

The length of time required for a crane load test depends on several factors, including the type of crane, its lifting capacity, site conditions and whether multiple cranes are being tested during the same visit.

For smaller lifting equipment such as jib cranes, testing may only take a couple of hours. Larger overhead travelling cranes or gantry cranes often require several hours, particularly where larger test weights need to be positioned safely before testing begins.

Preparation, setting up the test equipment and completing the necessary documentation can add time onto the job too.

 

How Often Should a Crane Be Load Tested?

Unlike routine servicing or LOLER examinations, crane load testing is not normally carried out on a fixed annual or six-month schedule. Instead, it is completed whenever circumstances require the crane’s lifting performance to be verified.

For many businesses, a crane may only undergo a load test when it is first installed or after significant repairs or modifications have been carried out. If no major changes have been made to the crane, ongoing servicing and statutory thorough examinations are usually sufficient to maintain safe operation.

If you are unsure whether your crane requires a load test, a qualified lifting equipment specialist can advise based on the work that has been carried out and the relevant regulations.

What Happens If a Crane Fails a Load Test?

If a crane does not perform as expected during a load test, it should not be returned to normal service until the cause has been identified and corrected. Engineers will investigate any issues discovered during testing, whether they relate to the hoist, brakes, electrical controls, structural components or another part of the crane.

Once any necessary repairs have been completed, the crane can be retested to confirm that it now meets the required performance and safety standards. This ensures that lifting operations only resume when the equipment can operate safely and reliably.

Crane Load Test Summary

Crane load testing plays an important role in confirming that lifting equipment can safely perform at its rated capacity before entering or returning to service. Whether following a new installation, major repair or refurbishment, a professionally carried out load test provides confidence that the crane is operating safely and as intended.

At Harold Potter, our experienced engineers carry out crane load testing across a wide range of overhead lifting equipment. If you have recently installed a new crane, completed significant repairs or would like advice on whether your equipment requires load testing, our team can help you arrange a safe, efficient and fully documented testing process.

Runway Beam Installation – Aburnets, Ilkeston

Harold Potter manufactured and installed a new 12-metre runway beam system to provide a reliable lifting solution tailored to the customer’s operational requirements.

As part of the project, we installed a new electrical power supply system for the runway beam, ensuring the crane could operate safely and efficiently across its full length. The existing hoist was removed and re-fitted onto the new runway beam system, allowing the customer to retain their existing lifting equipment while benefiting from an upgraded installation.

To complete the installation, we re-routed the existing electrical supply to feed the new runway beam, integrating the new system with the customer’s current infrastructure while minimising disruption to operations.

Once the installation was complete, the entire system underwent comprehensive testing to verify the safe operation of the runway beam, hoist and electrical components. Following successful testing, the installation was fully certified, providing the customer with confidence that the new lifting system met the required safety and operational standards.

How To Get An Accurate Crane Quote

 

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.

 

1T SWL Overhead Crane Installation

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.

What Influences The Cost Of A Crane?

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 3rd 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.
