After the equipment is started, if the electric shock does not work, and the cargo cannot be lifted, this situation is generally caused by the following reasons: voltage instability, if the voltage is 10% lower than the rated voltage, it will be like this. In other words, if the electrical appliance fails, such as a broken wire or poor contact, the electrical appliance will not work normally. The cargo is overweight. If the cargo exceeds the rated lifting capacity of the electric hoist, the electric hoist will not be able to lift the cargo.
