Product Description
ME shipbuilding gantry crane, a type of gantry crane of heavy lifting load, large span and high lifting altitude, is special for fragmented transport, end-to-end joint and turning operation of large ship hulls.
Main technical characteristics:
It have multiple functions of single hanging, hoisting, turnover in the air, slight horizontal turnover in the air and so on,
The gantry falls into two categories: single girder and double girder. To rationally utilize materials, the girder adopts optimum design of variable section;
·The upper crab has two main hooks, which are separately fixed at the outside of the girder.
·The lower crab has a main hook and a secondary hook, which are fixed at the center of the two girders,
·Both the upper crab and the lower crab can cross each other for operation
·All operating mechanisms employ frequency control;
·On the top of the girder at the side of rigid leg is equipped a jib crane to accomplish maintenance of upper and lower crabs To prevent storm attack, such safe and reliable anti-wind devices as rail clamp and ground anchor are furnished.
Function:
1. Simple and compact structure, stable performance.
2. The truss structure has light weight, strong wind resistance, and the price is relatively cheap compared with the box type.
3. Overload and low voltage protection device.
4. Suspension control and remote control.
5. Easy maintenance.6. To prevent the hook from hitting the top, set up protective covers and guardrails.
7. Circuit self-check protection device, running stroke limit protection phase current.
8. Outdoor cranes are equipped with lifting mechanism, electrical control box and rainproof device.
9. Anti-collision, sound and light alarm device. Equipped with guide rail clamp.
Safety device:
1. Weight overload protection device.
2. High-quality long-term bearing polyurethane material buffer.
3. Lifting limit switch and travel limit switch.
4. Emergency stop system.
5. Zero voltage protection.
6. Phase protection device.
