Abstract (en)
[origin: EP1300519A1] A hydraulic circuit includes a hydraulic pilot- operated control valve that controls an actuator for driving a front attachment. A pressure oil injection port that can be connected with a manual hydraulic pump is provided at a pilot line through which a pilot oil pressure is guided to the control valve. Pressure oil is supplied to the pilot line from the port with the manual hydraulic pump to switch the control valve, thus enabling emergency drive of the front attachment. The Structure can be achieved through a fairly simple modification, without having to provide a bypass line, a switching valve and the like.
