A winch, also known as a hoist, is a light and small lifting equipment that uses a drum to wrap steel wire rope or chain to lift or pull heavy objects. It can vertically lift, horizontally or obliquely pull heavy objects. Nowadays, electric winches are the main type. It can be used alone or as a component in machinery such as lifting, road construction, and mine hoisting. It is widely used due to its simple operation, large amount of rope winding, and convenient relocation. It is used as a vertical transportation tool. The vertical transportation tools used during construction include winches and tower cranes. If the building height is not large, a winch can be used directly.

A light and small lifting equipment that uses a drum to wrap steel wire rope or chain to lift or pull heavy objects The winch can vertically lift, horizontally or obliquely pull heavy objects. Mainly used for material lifting or flat towing in construction, water conservancy engineering, forestry, mining, docks, etc.

working principle:

It is a lifting tool powered by an electric motor, which rotates the drum through a driving device. Electric motors can be controlled for speed through frequency converters. The drum winds the steel wire rope and passes it through the pulley system to lift or lower the load on the crane hook, completing the vertical transportation and loading and unloading of the load.
