Dafang Crane, a professional goliath crane manufacturer and supplier in China, designs this gantry crane to handle massive loads in industrial settings. Customers often use it in shipbuilding, construction, and manufacturing industries, particularly in outdoor environments such as shipyards, logistics transfer centers, and fabrication sites.

Here is a comprehensive introduction to its definition, types, technical specs, applications, and features.

What Is Goliath Crane?

A Goliath Crane, also known as a gantry crane, is a large, heavy-duty lifting machine. It features a horizontal beam supported by two vertical legs that run on ground rails. This special design enables it to move heavy loads both horizontally and vertically along the tracks.

Goliath Crane Structure Design

The goliath crane is a highly efficient crane equipment. Its main structure includes main girders, supporting legs, a lifting trolley, and safety devices. Main Components:

  • Main Girders: The horizontal beam spans the working area. Single girder one (for lighter loads, 1–50 tons) or double girder one (for heavier loads, up to 800 tons).
  • Supporting Legs: Rigid steel or concrete structures support the girder. For spans over 30m, one leg is rigid and the other is flexible.
  • Trolley: Moves along the girder and carries the hoist, which lifts and lowers loads.
  • Wind-resistance Devices: Anemometers and rail clamps to secure the crane during storms.

  3. Construction: For lifting and placing steel structures, large prefabricated components like steel beams and concrete panels, heavy machinery, and for building bridges.
  4. Ports and Terminals: Loading/unloading containers, bulk materials (e.g., coal, gravel) using grab buckets.
  5. Mining and Quarries: Handling ores, equipment, and large-scale excavation materials.
  6. Power Plants and Steel Mills: Moving heavy industrial equipment and raw materials.

Goliath Gantry Crane Pros and Cons

3 Key Advantages

Heavy Load Handling and High Precision: Lifting massive objects that other common cranes cannot manage. Offering ±4 mm load positioning accuracy.

Versatility: Adaptable to various industries and tasks, including remote operation (two cranes controlled by one operator for enhanced safety).

Space Efficiency: Ground-level rails allow unobstructed overhead space compared to overhead cranes.

3 Key Limitations

High Initial Cost: Expensive to purchase, install, and maintain due to their size and complexity.

Infrastructure Requirements: Requires dedicated ground rails and strong foundations.

Mobility Constraints: Fixed to rail tracks, limiting movement to specific areas.
