Claims

[Scope of utility model registration request]

A jack with a ground plate 4 is attached to the tip 2a of the inner cylinder 2 of the telescoping arm P, which has an outer cylinder 1 fixed to the carrier side and an inner cylinder 2 telescopically inserted into the outer cylinder 1. This is an outrigger device in which a cylinder 3 is attached, and the jack cylinder 3 is attached to the inner cylinder 2 by a pivot pin 5 so as to be swingable and tiltable, and between the jack cylinder 3 and the inner cylinder 2. , expansion and contraction of the jack cylinder 3'
It operates in conjunction with the movement, and when the jack cylinder 3 is in a contracted state, the jack cylinder 3 is in a stored position with the lower part of the jack cylinder 3 tilted toward the carrier with the pivot support and the pin 5 as a fulcrum. An outrigger device characterized in that an appropriate posture control mechanism is provided which acts to hold the jack cylinder 3 in an operating position when the jack cylinder 3 is in an extended state.
