What Is a Goliath Crane?

Goliath Crane, also known as a Shipbuilding Goliath Crane or Shipyard Gantry Crane, is a large-scale gantry crane designed for ship construction and marine engineering projects. It is primarily used to lift hull blocks, ship sections, heavy equipment, and offshore structures in shipyards, dry docks, and shipbuilding areas.

The crane features a heavy-duty steel structure, a large-span design, and an advanced lifting system. With lifting capacities of 100–1600 tons, spans up to 185 m, and lifting heights to 90 m, it can handle large hull sections, block assembly, and equipment installation. The dual trolley system allows lifting, turning, and positioning of ship sections during construction.

It can be customized according to shipyard layout, vessel size and production requirements. Options include lifting capacity, span, trolley configuration, control system and safety equipment, making it suitable for large vessels, offshore projects and heavy-duty shipbuilding operations.

Why Are Goliath Cranes Used in Shipbuilding?

Goliath Crane is a lifting piece of equipment in modern shipyards, supporting large block handling, ship assembly, and heavy equipment installation.

  • Large Block Lifting: Handles prefabricated hull sections and heavy marine structures with lifting capacities from 100 to 1600 tons.
  • Hull Turning and Assembly: The dual trolley system enables air turning and precise positioning of large hull sections.
  • Higher Shipbuilding Efficiency: Reduces lifting operations and shortens dock assembly time through large-scale block handling.
  • Large Span Operation: Designed for wide shipyards with high stability in coastal and heavy-duty environments.
  • Advanced Engineering Design: Combines high-strength structures, synchronized control, and customized systems for large lifting projects.

Goliath cranes play a role in modern shipbuilding by supporting large block handling, precise assembly, and high-efficiency production in shipyards.

How Does a Goliath Crane Work?

A Goliath Crane completes shipbuilding lifting operations through coordinated movement of the crane structure, trolleys, and hoisting system. The working process includes positioning, lifting, air turning, alignment, and final placement of ship sections.

1. Crane and Trolley Positioning

The traveling mechanism moves the crane along rails to the lifting position. The upper and lower trolleys move on different tracks of the main girder and can operate independently or together according to the lifting process.

2. Lifting and Transfer

The hoisting system uses drums, wire ropes, and pulley blocks to lift and transport loads. The main hook lifting speed is typically 6–8.5 m/min, with inching speeds of 0.1–0.5 m/min for accurate positioning during assembly.

3. Air Turning and Hull Assembly

The upper and lower trolleys work together to lift and turn hull sections. By adjusting the movement of multiple hooks, the crane can complete 180° air turning and position sections accurately for hull joining.

4. Load Placement and Hook Release

The crane lowers the hull section to the installation position through variable speed control. After the section is fixed, the hooks are released to complete the lifting cycle.

Through the combined operation of traveling, hoisting, and trolley systems, the Goliath Crane provides precise handling for large hull sections and heavy components in shipbuilding projects.

Peças

A Goliath Crane consists of a heavy-duty steel structure, lifting system, trolley system, traveling mechanism, and control components. Each part works together to handle large hull blocks, marine equipment, and heavy loads during shipbuilding operations.

  • Main Girder: The double box girder supports the trolley system and carries the main lifting loads.
  • Rigid Leg: Connected to the main girder, the rigid leg provides structural support and maintains crane stability.
  • Flexible Leg: The hinged flexible leg absorbs structural movement caused by temperature changes and foundation deformation.
  • Upper Trolley: Equipped with two lifting hooks, the upper trolley is used for heavy lifting and hull section turning.
  • Lower Trolley: Works with the upper trolley for hull block lifting, positioning, and assembly.
  • Hoisting System: Includes motors, drums, wire ropes, and pulley blocks for lifting and lowering loads.
  • Traveling Mechanism: Drives the crane and trolleys along rails for movement across the shipyard.
  • Electrical Control System: Uses PLC and variable frequency control for speed adjustment and crane operation.
  • Safety Devices: Includes overload protection, rail clamps, wind protection, and anti-collision systems.

The combination of these components allows the Goliath Crane to perform heavy lifting, hull assembly, and precision positioning work in large-scale shipbuilding projects.
