Claims

[Scope of utility model registration request]

A jack with a ground plate 5 attached to the tip 3a of the inner tube 3 of a telescoping arm 1 having an outer tube 2 fixed to the carrier side and an inner tube 3 telescopically inserted into the outer tube 2. This is an outrigger device having a cylinder 4 attached thereto, with the cylinder rod 8 facing upward, the tip 8a of the rod 8 fixed to the inner cylinder 3, and the cylinder tube 7 suspended. However, it is installed in a non-rotatable state,
Further, the ground plate 5 has a link member 10 pivotally attached to the lower end 7a of the cylinder tube 7 so as to be swingable in the direction of expansion and contraction of the telescoping arm 1 and to be movable up and down within a certain range with respect to the cylinder tube 7. While connected to the lower end 10b of the cylinder tube 7, the link member 10 cannot tilt in the position where the link member 10 moves upward with respect to the cylinder tube 7. A stopper 11 is provided at a suitable position in the inner cylinder 3 to allow the link member 10 to tilt toward the carrier when the link member 10 is moved downward, and a stopper 11 is provided at a suitable position in the inner cylinder 3 so that the link member 10 can be tilted toward the carrier side when the link member 10 is moved downward. An outrigger device comprising a link abutment member 9 that abuts against an abutment member 12 on the member 10 side to forcibly tilt the link member 10 toward the carrier.
