The role of the hoist: the hoist can lift the weight vertically or horizontally or tilt. Mainly used in construction, water conservancy engineering, forestry, mining, wharf, etc. materials lifting or flat towing.

The winch is divided into two types: manual winch and electric winch. Now it is mainly electric winch. It can be used alone or as a component in machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large amount of rope winding, and convenient displacement.

The structure of the winch: the winch converts the electrical energy into mechanical energy through the motor 1, that is, the rotor output of the motor, after the V-belt 2, the hoist structure hoist structure shaft 3, the gears 4, 5 reduce the speed, and then drive the drum 6 to rotate. The reel winds the wire rope 7 and passes the pulley sets 8, 9 to lift or drop the load Q of the crane hook 10, transform the mechanical energy into mechanical work, and complete the vertical transportation of the load.

The winch includes construction winch and coaxial winch; the main products are: JM electronically controlled slow speed large tonnage winch, JM electric; controlled slow speed winch, JK electronically controlled high speed winch, JKL manual control fast slipping winch, 2JKL manual control double fast slipping Unwinding winch, electronically controlled manual dual purpose winch, JT speed regulating winch, KDJ mini winch, etc.
