The power of the winching-and-lifting ship lifter is transmitted to the two sets of reel groups on both sides of the gearbox through the coupling and the gear box. Each drum is wound with hoisting wire ropes and balancing wire ropes. One end of the hoisting wire rope is wound and fixed on the drum, and the other end is connected to the ship reception chamber through the equalizing cylinder device to realize the rise and fall of the chamber.

The driving part of the winching ship lifter is mainly composed of the main hoist gearbox, synchronous shaft, motor and so on.
