Abstract

PURPOSE: To surely brake at stop of a motor by releasing a brake by means of a pressure oil which is sent via a control valve from a pump driven by a motor and inhibitting supply of a pressure oil sent from the motor for a brake cylinder by means of another control valve.
CONSTITUTION: A pump 15 independent from a pump 1 which drives a hydraulic motor 2 is provided and driven by the motor 2. Provided between the pump 15 and a brake cylinder 11, a directional control valve 16 is switched by a pressure oil which is fed via a pilot circuit 18 by the pump 15. Provided between said control valve 16 and a shuttle valve 7 in a closed circuit, another directional control valve 7 is moved with a control lever 8 which is connected to it by a link 20 to be switched.
