Patent ID: 7328810

Claim:
A crane support comprising: (a) a mounting frame; (b) a pedestal having a crane supporting upper end, and having a front end, a rear end, and a longitudinal axis extending from the front end to the rear end, the pedestal being mechanically linked to the mounting frame; (c) crane mounting means fixedly attached to or formed wholly with the crane supporting upper end of the pedestal; and, (d) means for alternately pivoting and counter-pivoting the pedestal comprising an axle and comprising laterally extending outriggers, each laterally extending outrigger having a proximal end and a distal end, each laterally extending outrigger comprising a plurality of segments and first telescoping means connected operatively to the segments for alternately laterally extending and retracting the distal ends of the laterally extending outriggers, the means for alternately pivoting and counter-pivoting the pedestal being connected operatively to the pedestal, the means for alternately pivoting and counter-pivoting the pedestal controlling pivoting movements of the pedestal about the longitudinal axis while the pedestal remains mechanically linked to the mounting frame; the means for alternately pivoting and counter-pivoting the pedestal further comprising a first plurality of quill and slide shaft combinations attached to the distal ends of the laterally extending outriggers, and second telescoping means being operatively connected to the first plurality of quill and slide shaft combinations, the second telescoping means being adapted for alternately downwardly extending and upwardly retracting the first plurality of quill and slide shaft combinations.
