Sometimes, the voltage of the hoist motor is normal, but the electric hoist does not work, there may be other reasons, such as: the motor is burned, the brake wheels are rusted, and the motor does not rotate. In addition, it is strictly forbidden to use electric hoist for overloading. When the cargo is overloaded, the hoist can’t lift the cargo, the motor only sounds and does not run. In serious cases, it will burn the motor and even cause an accident. Then stop the machine immediately to reduce the cargo; Hoist works at rated power.
