Electric hoist is an electric hoist that uses lifting chains for lifting traction, which belongs to light and small special lifting equipment, which can be directly used to lift heavy objects, and can also be used as part of the lifting mechanism of other lifting equipment. The operation of the electric hoist is very simple, but it is also prone to encounter certain problems that cause the equipment to not be used normally.

　　When the power cord or control circuit of the electric hoist is disconnected, the device obviously cannot be started. Then we can check the power cord or control circuit of the equipment, and if there is a break or poor contact, just repair or replace it.

　　The control circuit of the electric hoist also has a fuse, when the fuse is burned by abnormal current, the circuit will be disconnected, if the fuse is not completely blown off, the switch will also jump open and disconnect the circuit, then the electric hoist can not be used, then only need to find out the reason why the fuse is burned and replace it.

　　The electric hoist has a phase protection safety protection device, if the phase of the equipment power cable is connected to the wrong one, the phase protection effect will be activated, and the device startup program will be forcefully locked. At this time, the power cables of the two wrong phases will be adjusted to unlock the normal starting hoist.
