レーキの非常装置。 A brake device that tightens a brake band to generate braking force by swinging a brake lever loaded with a spring, and releases the brake by expanding and contracting a double-acting cylinder connected to the brake lever with hydraulic pressure. The brake release side oil chamber is communicated with the hydraulic power source circuit via the brake release operation hydraulic valve, and the brake operation side oil chamber is
The hydraulic pressure source circuit or tank circuit is selectively communicated via another hydraulic switching valve, and only when the brake application side oil chamber communicates with the hydraulic pressure source circuit, the pressure oil in the brake release side oil chamber is connected to the hydraulic pressure switching valve. A spring-loaded brake emergency device with a hydraulic circuit configured to be open to the tank circuit.
