Claims

[Scope of utility model registration request]

A slide beam with a float at the tip extends from the outrigger box in the vehicle width direction and is retractably fitted into the outrigger box.The outrigger box can be rotated up and down using one end as a fulcrum relative to the crane's lower running body frame. In an outrigger device for a wheeled crane, the cylinder tube of a jack cylinder that moves the outrigger box up and down is attached to the cylinder attachment part of the lower traveling body frame, and the rod end is attached to the outrigger box, respectively. The jack cylinder is
The upper end of the cylinder tube is pivotally connected to the cylinder mounting portion of the lower vehicle frame so as to be rotatable around a horizontal axis in the longitudinal direction, and a convex portion is provided on at least both front and rear sides of the lower outer peripheral surface of the cylinder tube. An outrigger device for a wheeled crane, characterized in that cylinder receiving parts are provided on both front and rear sides of the lower part of the mounting part, the cylinder receivers coming into contact with the convex parts on both sides and receiving horizontal loads in the longitudinal direction of the jack cylinder.
