置。The drum that lifts and suspends the load, this drum,
In a shaft hoisting machine that is mechanically coupled by a coaxial shaft to an electric motor that drives the drum, and a disc brake that is provided with a brake pad and that brakes the rotation of the drum, the rotational speed of the brake disk that is provided on the shaft is a rotation speed detector that detects the rotation speed, and a circuit that inputs the output of the rotation speed detector and a command signal that commands the rotation direction of the electric motor, determines the static torque direction due to the load, and changes the hanging drop prevention current. A control device for a shaft hoisting machine, characterized in that the brake pad is appropriately loosened before starting, and a slight rotation of the brake disc at that time is detected.
