Claims

[Scope of utility model registration request]

It consists of an outer box 2 that is attached to a support base such as a chassis frame of a vehicle, and an inner box 3 that is telescopically inserted into the outer box 2. Tip part 3 of the inner box 3 of the telescopic girder 1 that can be expanded and contracted
A pair of overhanging arms 2.2 configured by equipping a with a ground plate 6
This is an outrigger device in which the ground plate 6 is mounted in a substantially horizontal plane with respect to the tip 3a of the inner box 3 about a fulcrum pin 8 provided on the tip 3a. The swing arm 7 is attached to the distal end 7b of a swing arm 7 which is connected so as to be swingable, and the swing arm 7 is swung by the telescopic displacement force of the telescopic hydraulic cylinder 4, so that the telescopic hydraulic cylinder 4
When in the extended state, the ground plate 6 is in the first swing position where it extends in the extending direction of the inner box 3, and when the telescopic hydraulic cylinder 4 is in the contracted state, the ground plate 6 is in the first swing position.
An outrigger device characterized in that it is configured to be positioned at a second swing position that is closer to the retraction direction of the inner box 3 than the swing position.
