Electric hoist is a kind of electric hoist that uses lifting chain as lifting traction. It belongs to light and small special lifting equipment. It 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 easy to encounter some problems that cause the equipment to not work properly.

        When the power line or control circuit of the electric hoist is disconnected, the equipment obviously cannot be started. Then we can check the power line or control circuit of the equipment. If there is a break or poor contact, we just need to repair or replace it.

        There are also fuses in the control circuit of the electric hoist. When the fuse is burnt 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 can not be used. At this time, it is only necessary to find out the cause of the fuse burning and replace it.

       The electric hoist has a safety protection device with phase protection. If the phase of the power line of the equipment is connected incorrectly, the phase protection function will be activated, and the equipment startup program will be locked compulsorily. At this time, the normal starting electric hoist can be unlocked by switching the power lines of the two wrong phases.
