Shipbuilding gantry crane

Shipbuilding gantry cranes are core lifting equipment in the shipbuilding industry. They feature a double-girder gantry structure design, with rated lifting capacities ranging from 100t to 3800t and typical spans reaching 40 to 185 meters . This equipment is equipped with a double-trolley four-hook system and a maximum lifting height of up to 60 meters, meeting the requirements for hull block lifting and modular construction of offshore platforms .

Advantages & Features

Structural Composition

Taking a typical ultra-large tonnage product as an example, its core components include:

1. Main Girder Structure: Designed with a single main girder or double main girders to bear enormous loads.
2. Hoist Trolley System: This is key to achieving complex lifting functions. For example, the 2000t gantry crane is equipped with three trolleys (double trolleys on top and a single trolley below), enabling single-hook lifting, multi-hook tandem lifting, and空中 turning through combination.
3. Crane Travel Mechanism: Drives the entire machine along the rails. For equipment with ultra-large spans (e.g., 200 meters), the crane mechanism uses multi-stage balance beams (e.g., four-stage) combined with dozens of wheel sets for drive, ensuring stable operation.
4. Metal Structural Components: Includes support structures such as rigid legs and flexible legs, with single components potentially weighing over a thousand tons.
5. Intelligent Control System: Integrates intelligent systems such as anti-sway automatic positioning and safety monitoring, enabling precise control and safety management.
