インチブレーキ。 A motion transmission mechanism connected to the brake band of the crane winch is equipped with a spring for tightening the brake band, and the cylinder and brake pedal are connected.
The brake can be tightened or released by operating either the cylinder or the brake pedal, and the cylinder and brake pedal are connected to each other via a switching valve and a solenoid valve that are switched in conjunction with the directional switching valve of the winch's hydraulic motor. At the same time, the switching valve was connected to the hydraulic power source via a bypass path so that the brake of the winch was released with pressure oil being supplied to the cylinder, and the solenoid valves were connected in series. A winch brake for a crane, which is connected to a power source via a manual changeover switch and a limit switch operated by the movement of a foot pedal, and is provided with a relay for maintaining power supply to the solenoid valve in parallel with the solenoid valve.
