Claims

[Scope of utility model registration request]

A telescoping arm 1 has an outer cylinder 2 fixed to the carrier side and an inner cylinder 3 telescopically inserted into the outer cylinder 2. A ground plate 5 is attached to the distal end 3a of the inner cylinder 3. This is an outrigger device equipped with a cylinder 4, which has a cylinder rod 8 facing upward, and a tip 8a of the rod 8 fixed to the inner cylinder 3 to suspend a cylinder tube 7. condition and the cylinder tube 7
The ground plate 5 is fixed so as not to rotate, while the ground plate 5 is made swingable in the direction of expansion and contraction of the telescoping arm 1 by means of a ball joint device 10 provided at the lower end of the cylinder tube 7. When the jack cylinder 4 is retracted, it comes into contact with the ground plate 5, forcing the ground plate 5 to rotate outward from the horizontal position about the ball joint device 10, and tightens the jack. An outrigger device characterized in that a ground plate abutting member 9 is provided that acts to hold the ground plate 5 in a posture along the outer surface of the cylinder tube 7 when the cylinder 4 is fully retracted.
