機械の空圧回路。 In wheel-type construction machinery, the inclination angle of the steering handle can be changed slightly between driving and work, and the wheel brakes for the front and rear wheels and the parking brake for the drive shaft are operated by air pressure. A limit switch is installed on the floor to detect the inclination angle of the operating handle, and this limit switch is connected to an electromagnetic switching valve that switches between the wheel brake used during work and the parking brake used when parking, and these electric circuits are connected to the engine switch. A pneumatic circuit for wheel-type construction machinery that is connected in series with a wheel-type construction machine.
