Abstract
An improved mounting arrangement for the vertical cylinder of an extensible outrigger assembly includes laterally extending plates on the cylinder that are connected to the beam side walls by two transverse mounting pins, one of which also functions as a connection point for the horizontal cylinder that actuates the outrigger beam. In the preferred embodiment, the vertical cylinder has a self-storing float and a piston rod that is held against rotation to assure correct alignment of the float.
Claims7
A mounting arrangement for the vertical cylinder of an extensible outrigger assembly for truck cranes or the like wherein the outrigger is mounted on said crane and includes an extensible and retractable hollow beam having an outer end with opposite side wall means, said beam being connected to and actuated by an extensible and retractable horizontal cylinder rod that extends outwardly within the beam, a power source on said crane for actuating said cylinder rod, a vertical hydraulic cylinder mounted at the outer end of the beam, a power source on said crane for actuating the vertical cylinder, said vertical cylinder including a casing, an extensible and retractable rod and a piston connected thereto and wherein said rod and piston are movable in the casing, the improvement comprising a mounting means fixed to the casing of the vertical cylinder comprising a pair of parallel vertically disposed plates extending respectively alongside said beam side wall means, a first connector pin extending through the said plates and side wall means for securing the beam and vertical cylinder in assembled relationship, a fitting secured to the outer end of the horizontal cylinder rod, and a second connector pin spaced from said first connector pin extending through the said plates and side wall means and said fitting to secure the beam and vertical cylinder and horizontal cylinder rod in assembled relationship.
