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.
