Abstract

PURPOSE: To secure operation with safety by installing a gearing mechanism, which is to reinstate a selector valve to the neutral position according to the output of a flowmeter provided between the selector valve and oil-hydraulic apparatus, and thereby permitting the moving part of the oil-hydraulic apparatus to move by an amount corresponding to that amount the control lever is operated.
CONSTITUTION: An oil pressure motor 15 as working oil flowmeter is equipped in the piping 5a between the selector valve 13 and oil pressure cylinder 5, and a gearing mechanism G is constituted with No.1, No.2 pinions 16, 19 and No.1, No.2 racks 17, 18. When the operating part 20b of the control lever 20 is shifted to the right in order to lift a boom 3, the pinion and rack 18 will work to change over the selector valve 13 to the left, and the pressure oil is fed to the cylinder 5 through the motor 15 to expand it. At this time, turn of the motor 15 and pinion 16 will move the rack 17 to the right and the rack 18 to the left, and thus the selector valve 13 is reinstated to the neutral position. The expansion of cylinder 5 is thus stopped.
