Fixed dock cranes (or mast crane, or derrick) are commonly seen at dockside for lifting materials and goods between vessels and shore. This dock crane is composed of platform, hoisting mechanism and luffing mechanism, which is for handling 22,000m3 LPG tank.
Features:
1.Adopt 4 driving system for lifting mechanism, and 2 driving system for luffing mechanism.
2.The entire mast crane chassis adopt basin support on concrete platform, which can effectively ease the crane horizontal and vertical deformation.
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, lifting half load speed is 2 times of the full load speed.
5.Using inverter, encoder and a series of electronic control system to ensure the 4 lifting motors keep synchronous running.
