Title:
PRESSURE INCREASING DEVICE FOR VEHICLE FOR HIGH LIFT WORK
Document Type and Number:
Japanese Patent JP2018059521
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure increasing device for a high lift work vehicle equipped with a hydraulic type crimp tool capable of holding a compression object without deformation.SOLUTION: A booster apparatus 12 for a vehicle 1 for high lift work to feed working oil boosted by a booster cylinder 13 to a hydraulic type crimp tool 100 comprises: a supply oil passage 15 for connecting the pressure chamber 13a of the pressure cylinder 13 and the hydraulic type crimp tool 100; an electromagnetic changeover valve connected to the supply oil passage 15 and interchanged between a state, in which the working oil is fed to the supply oil passage 15, and a state, in which the working oil is not fed; and a distance measuring means for measuring the distance between the movable part 100a of the hydraulic type crimp tool 100 and the pressure object by the hydraulic type crimp tool 100. The electromagnetic changeover valve is changed over on the basis of the detection value of the distance measuring means.SELECTED DRAWING: Figure 1
