The shipbuilding gantry crane has a large hoisting capacity, large span, multiple functions and high efficiency, especially for the wharf (or berth) for large hull, butt and turning sections. Shipbuilding gantry crane include single girder type ship building gantry crane and double girder shipbuilding gantry crane.
Shipbuilding gantry crane is mainly composed of steel door frame, the car, the car running, improve organization structure and electrical equipment, it has three kinds of structure forms, such as monorail trolley, trolley, and the upper and lower trolley.
1. It can achieve lift, air turnover, slight horizontal flip and other functions
2. Elevating mechanism and travel agency adopt frequency conversion speed adjustment
3. Safe and reliable windbreaks (such as rail tongs and anchor gear) can prevent storm attacks
4. Upper trolley and the lower trolley can be overlapping, and lower trolley has a main hook and auxiliary hook, it fixed in the middle of the two beams, the upper trolley has two main hook, respectively fixed on both sides of the main girder
The shipbuilding gantry crane has a large hoisting capacity, large span, multiple functions and high efficiency, especially for the wharf (or berth) for large hull, butt and turning sections.
To ensure the safety, the following safety devices are equipped in shipbuilding gantry crane:
1. Limit switch for traveling and lifting
2. Weight overload protection device
3. Emergency stop device, lifting height limit device
4. Warning indicator: flashing lights and warning sound.
5. Rain cover for outside hoist, driving units, electrical cubicle.
6. Voltage lower protection device, phase sequence protection device
