The lift system

In many power machinery and transport machinery such as motors, fans, pumps, gearboxes, automotive drive shafts, marine propeller shafts and oil rigs, the torque in drive shafts is an extremely important parameter for the entire power system. A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock and the canal inclined plane. A vertical ship lift is large electromechanical equipment for a cargo ship passing dam. It's composed of four parts which includes an upper lock head, lower lock head, ship reception chamber and the main lift system. The main lift system consists of lifting equipment, corresponding control equipment and testing equipment distributed in four lifting points. Each lifting device at different lifting point includes DC motor, reduction gearbox, hoist drum wrapped lifting rope and hydraulic brakes.
