Shipbuilding gantry crane

Shipbuilding gantry crane is a specialized lifting equipment that works on shipyards, slipways, or platforms in shipyards to perform segmented lifting and flipping operations of ship hulls. Its task is to transport all the parts required for manufacturing the hull (ribs, steel sections, steel plates, etc.) from the ground transport equipment to the manufacturing site. This type of transportation work must be able to complete the task quickly over a long transportation distance. Therefore, the decision on the number of cranes is based on the principle of being able to reach the foundation area of the entire dock, while each crane does not interfere with each other. Henan Tianlu can provide you with suitable shipbuilding gantry cranes according to your operating conditions.

Structural characteristics of shipbuilding gantry crane

Due to the large span of shipbuilding gantry cranes, the gantry usually adopts a type of one side rigid leg and one side flexible leg, that is, one side rigid leg is fixedly connected to the main beam, and the other side flexible leg is connected to the main beam through a flexible hinge. There are two types of main beams: single main beam and double main beam. According to the requirements of shipbuilding technology, shipbuilding gantry cranes should have multiple functions such as single lifting, double hook lifting, triple hook lifting, aerial turning of ship sections, and micro rotation in the air, especially meeting the requirements for turning and closing of ship sections. Shipbuilding gantry cranes usually have two small cars on top and bottom. The upper and lower cars travel on their respective tracks, and the lower car can pass through the upper and lower cars. The upper trolley is equipped with two lifting mechanisms with the same lifting capacity, and the lifting points span the outer side of the main beam. The two sets of lifting mechanisms can act separately or in combination to complete the double hook lifting and rotation of the ship section. The two hooks are equipped with lateral movement mechanisms, which can move horizontally separately to complete the micro movement and micro rotation of the workpiece, and can be accurately aligned when closed. The lower trolley is equipped with a main hook and a secondary hook. The main hook can be lifted separately or combined with the two hooks of the upper trolley to complete three hook lifting and aerial flipping. The auxiliary hook is usually used for lifting small items.

Product Features

This shipbuilding gantry crane has functions such as lifting, hoisting, and segmental aerial flipping. The characteristics of turning and closing the ship's hull are particularly prominent. By using two small cars for segmented flipping operations, the first step is to adjust the lifting and lowering to ensure that the entire segment is supported by the cars.

1. Large lifting capacity, large span, and high lifting height.

2. It has multiple functions such as single hook lifting, double hook lifting, triple hook lifting, segmented aerial turning of the ship body, and micro rotation in the air.

3. Set up two small cars. The upper and lower cars travel on their respective tracks, and the lower car can pass through the upper and lower cars.

4. Equipped with a lateral movement mechanism, it can move horizontally separately to complete micro movement and micro rotation of the workpiece, and can accurately align when closed.

5. Equipped with two sets of correction devices, an upper correction device and a lower correction device, to prevent the large vehicle from running in a skewed manner. Ensure the safe operation of the crane.
