。In the chain block, the chain block includes a power relay that applies three-phase AC power to an electric motor, a speed change relay that switches the driving speed of the motor between low speed and high speed, and a stop relay that detects overload operation of the motor. A chain block characterized in that a bistable switching contact is provided that is turned off by a stop relay to interrupt the hoisting operation of the motor, and a set relay that turns the switching contact back on is connected in parallel to a power supply relay for driving the motor down. load control device.
