ABSTRACT:
An automatic hydraulic shut-off system for use with a hydraulic valve and a work apparatus which is retained under hydraulic pressure even when the hydraulic line is broken inadvertently. A lock valve is connected in the line and senses the loss of hydraulic pressure, and the valve is actuated in response to the pressure drop and retains the work apparatus in a pressurized condition to thereby avoid undesired movement in response to the loss of pressure.
