Electric hoist is a type of electric hoist that uses lifting chains for lifting and traction. It is a light and small special lifting equipment that can be used directly to lift heavy objects or as part of the lifting mechanism of other lifting equipment. The operation of an electric hoist is very simple, but it is also easy to encounter certain problems that may cause the equipment to not function properly.

　　When the power cord or control circuit of the electric hoist is disconnected, the device clearly cannot start. So we can check the power cord or control circuit of the device. If there is a break or poor contact, just repair or replace it.

　　There is also a fuse in the control circuit of the electric hoist. When the fuse is blown by abnormal current, the circuit will be disconnected. If the fuse is not completely blown, the switch will also jump and disconnect the circuit. At this time, the electric hoist cannot be used anymore. Simply find out the cause of the fuse being burned and replace it.

　　The electric hoist has a phase protection safety protection device. If the phase of the equipment power line is connected incorrectly, the phase protection function will be activated, forcing the device startup program to be locked. At this point, by swapping the power lines of the two wrong phases, the normal start of the electric hoist can be unlocked.
