Claims

[Scope of utility model registration request]

A support base 17 such as a vehicle chassis frame has an outer box 2 attached to the support base 17 side, and a float 5 that is slidably inserted into the outer box 2 and has a float 5 at its outer end 3a. A pair of overhanging arms Z, Z, which are adapted to expand and contract the installed inner box 3 appropriately by means of an expanding and contracting hydraulic cylinder 4 installed between the outer box 2 and the inner box 3, are oriented in opposite directions and are In the first rotation position, the float 5 is in a non-grounded state, and in the second rotation position, the float 5 is in a non-grounded state.
The X-shaped outrigger is attached so as to be rotatable in the vertical direction so as to be in contact with the ground, and the float 5 is attached to the tip end surface 3b of the inner box 3, and It is connected via an appropriate swing arm 6 so that it can be positioned in two positions: a first swing position located closer to the inside and a second swing position extending outward beyond the tip surface 3b, and furthermore, One end 4b of the telescopic hydraulic cylinder 4 is connected to a proper position of the swing arm 6, and when the hydraulic cylinder 4 is in the contracted state, the float 5 is positioned at the first swing position, and when the hydraulic cylinder 4 is in the extended state, the float 5 is positioned at the first swing position. An X-type outrigger characterized in that the float 5 is configured to be positioned at the second swing position.
