Abstract

PURPOSE: To shorten the time to start the machine operation again after the trouble is fixed, in case a hydraulic power machine does not stop due to trouble occurring in the control system, by stopping the machine by the water pressure produced in a steel pipe as an emergency measures.
CONSTITUTION: When the hydraulic power machine does not stop due to trouble occurring in the control system, a solenoid distributing valve 3 and a regulating valve 8 are actuated to introduce the pressure water of the water pressure steel pipe 5 into the oil-water cylinder 7, and then the oil is introduced into the servomotor 1 to close its operation. By this structure, the time to start the machine operation again can be shortened, as the operation can be started by closing the manually operated valve 9 only after the trouble is fixed.
