Electric hoist is a lightweight and small lifting equipment installed on cranes or overhead cranes. It has the characteristics of small size, light weight, simple operation, and convenient use, and is often used in industrial and mining areas, storage terminals, and other places. Electric hoists need to be powered on and rely on electric drive to lift heavy objects. How is the wiring of electric hoists.

Firstly, using a multimeter side resistor, the three wires coming out of the electric hoist motor include one common wire and the other two incoming wires for the winding. If the main and auxiliary windings are not separated, the resistance of the two windings' incoming lines and the common terminal line is the same. If the main and auxiliary windings are separated, the resistance of the main winding and the common terminal is greater than the total resistance of the auxiliary winding and the common terminal.

To determine the main and auxiliary windings, check the number of wires in the electric hoist motor. Separate the main and auxiliary windings and require them to be in both forward and reverse directions. The number of wires coming out of the motor should be at least 4. If there are 3 wires, it can be determined that there is no distinction between the main and auxiliary windings.

The wiring of an electric hoist mainly involves the operation of the hoist body and handle. Generally, there are six buttons on the operating handle, namely red, green, and four directional keys. The hoist has a sub row of wiring terminals, which is used to connect the hoist body and handle. Wiring can be done according to the corresponding color of the wire.
