ーン車の油圧サスペンシヨン装置。 An upper pressure chamber and a lower pressure chamber are interposed between the chassis frame and the axle and are defined by a piston.
In the hydraulic suspension device for a crane vehicle, the hydraulic suspension device includes a hydraulic cylinder connected by an oil passage provided with a flow rate regulating valve having a throttling action when the piston is extended, and has outriggers at the front and rear parts of the chassis frame. A blocking means for substantially preventing the discharge of hydraulic oil from the upper pressure chamber and the lower pressure chamber is disposed in the oil path, and an operating switch is provided for activating the blocking means, and the blocking means is inactivated. After jacking up the vehicle height to a desired height using the outriggers, the actuating switch is operated to actuate the blocking means, trapping the hydraulic fluid in the upper pressure chamber and the lower pressure chamber to reduce the hydraulic pressure. A hydraulic suspension device for a crane vehicle, characterized in that a cylinder is held in a locked state and the outrigger is retracted in this state.
