Parts of a gantry crane

Shipbuilding gantry crane is a kind of heavy lifting equipment mainly composed of a gantry structure, hoisting mechanism, trolley running mechanism, trolley traveling mechanism, and a control system. The following are the functional characteristics of each component.

Gantry structure: It consists of rigid outriggers, flexible outriggers, and main beams, forming a stable gantry frame with a maximum span of up to 185 meters, with good structural strength and wind resistance.
Lifting mechanism: Adopts Elektroseilzug or wire rope winch system, equipped with frequency conversion drive to realize high-precision (millimeter level) lifting and lowering control, the maximum lifting capacity can be up to 1500 tons.
Trolley running mechanism: The lifting trolley is mounted on the main beam, which can be moved transversely, and some models adopt a down double trolley design, which is convenient for hull segment turning and accurate positioning.
Trolley running mechanism: The whole machine can move longitudinally through the track running wheels, and adopts a separate drive + deskewing system to prevent runaway, adapting to the demand of long-distance operation in the dockyard.
Control system: Integrated PLC + frequency conversion drive, with automatic anti-shaking, synchronized lifting, electronic limit, and other functions, to enhance operational safety and energy efficiency.
Safety protection devices: Including torque limiter, anemometer, interlocking limit, etc., to ensure emergency braking under overloading, strong wind, and other working conditions.
Auxiliary structures: Such as S-shaped staircases, maintenance platforms, etc., to enhance the convenience of maintenance, and some high-end models are equipped with an elevator and an air-conditioned cab.

How does a Shipyard gantry crane work?

The working principle of the shipbuilding gantry crane (gantry crane) is to realize the lifting operation of heavy objects through the cooperative cooperation of three parts: hoisting mechanism, trolley running mechanism, and large trolley traveling mechanism.

The main workflow is as follows:

• The hoisting mechanism completes the vertical lifting and lowering of the heavy objects through the wire rope winch system.
• The lifting trolley mounted on the main girder moves transversely along the track to realize the horizontal displacement of the load.
• The gantry system covers the working area by moving longitudinally along the ground track through the bottom travelling wheels.
