Claims

[Scope of claim for utility model registration] An outer cylinder horizontally fixed on the chassis frame of a vehicle, a pair of left and right inner cylinders that are telescopically inserted into the left and right outer end openings of the outer cylinder, and a pair of left and right inner cylinders. A device for supplying oil to the jacks of an outrigger device consisting of hydraulically driven jacks fixed vertically to each outer end of an inner cylinder, the base ends of which are connected to the jacks on the left and right sides, respectively. It is connected to a piping joint provided inside the outer cylinder at the center portion in the left-right direction of the outer cylinder, extends from there in the corresponding jacking direction through the outer cylinder and the inner cylinder, and has its tip located within the inner cylinder. a flexible hose whose proximal end is connected to the distal end of the fixed piping, extends from there toward the proximal end of the inner cylinder, is inverted and folded back within the inner cylinder, and reaches the distal end of the inner cylinder. and an outrigger configured to support the pair of piping joints via a single support shaft that penetrates the left-right center cylinder wall of the outer cylinder and is perpendicular to the direction of expansion and contraction of the inner cylinder. Oil supply device for jacking equipment.
