ABSTRACT:
A pair of fixed parallel transport rails for the outrigger box of a mobile crane are installed at the bottom of the crane chassis frame. The outrigger box is held on the chassis frame by four removable tapered pins. One jack cylinder on the outrigger box is trunnion mounted so that it can be tilted to clear the bottom of the chassis frame during removal and installation of the outrigger box. The outrigger box is equpped with transport track engaging rollers. To remove the outrigger box from the crane chassis, the box is unweighted to allow ready removal of the tapered pins. The outrigger box is then lowered until its rollers are resting on the two transport rails. A collar which retains the trunnion mounted jack cylinder of the outrigger box upright is released, and that jack cylinder is lowered to a stabilized inclined position where it can pass under the chassis frame. The outrigger box is then moved in one longitudinal direction along the transport tracks until the rollers near the end of the outrigger box having the trunnion mounted jack cylinder engage end stops on the tracks. The outrigger box is then lifted from the tracks and set aside in a desired manner.
