Winged hoist: a mechanical device that uses steel cables or steel cable pulley groups as lifting devices connected to gates, and drives the hoisting drum to wind and release steel cables through a gear transmission system to drive lifting and lowering. The double lifting point hoisting hoist is a synchronous operation that connects two single lifting point hoists together through a connecting shaft, and can be driven on one side or both sides. A winch hoist is usually a device used for one gate, installed on a gate pier above the top of the gate slot. The capacity of the winch hoist produced and put into operation in China has reached: opening force of 6000kN, opening and closing stroke of 30m, and opening force of 4000kN, opening and closing stroke of 120m.

The winch hoist is usually used for one gate and installed on the gate pier above the top of the gate slot. Nowadays, the capacity of the winch hoist hoist produced and put into operation in China has reached a lifting force of 6000kN, a lifting stroke of 30m, and a lifting force of 4000kN, a lifting stroke of 120m. Therefore, its classification is as follows:

1. The winch hoist is divided into fixed and mobile types, and the machinery that uses steel cables or steel cable pulley groups as lifting devices to connect with the gate and drives the lifting and lowering through a gear transmission system by winding and releasing the steel winch hoist cable is called a fixed winch. It has the characteristics of simple structure, easy manufacturing, and convenient maintenance and repair, and can be widely used for the opening and closing of various types of gates.

2. The hoist hoist can be divided into single lifting point and double lifting point. The double lifting point hoist hoist hoist is connected to the two single lifting point hoists through a connecting shaft for synchronous operation, and can be driven on one side or both sides
