A Derrick Crane is docking equipment installed on vessels or dockside. Derrick crane consists of derrick and hoisting mechanism. There are 3 or 4 steel wires connecting the derrick and hoisting mechanism, which controls hoisting mast goes up and down. A separate steel wire sling runs under the hoisting mast with a hook as the hoisting mechanism.
Features of Weihua Derrick Crane:
1. There are 4 driving system for the hoisting mechanism, 2 driving system for luffing mechanism.
2. The whole derrick crane chassis adopt basin support on concrete foundation, which can effectively ease the horizontal and vertical deformation of the derrick crane.
3. Multi-layer winding line reel drum. Hoisting winding drum wrapped with 4 layers of wire rope, and luffing drum is wrapped with 5 layers of wire rope.
4. Complete frequency control, half load lifting speed is 2 times faster than the full load lifting speed.
5. Inverter, encoder and electronic control system to ensure the 4 hoisting motors keep synchronous working.
Weihua provide professional lifting equipment solutions, customized cranes, Crane Components, installation, after sale service. Weihua products export to 110 countries such as Russia, Thailand, Malaysia, Egypt, Saudi Arabia, Parkistan, the Philippines, Mexico, etc. We have confidence to provide you with the professional solutions and right products.
