Abstract:
An apparatus for supporting and accurately positioning a massive article, such as a commercial aircraft landing gear, under a second separately supported second article, such as a commercial aircraft, to facilitate attachment of the articles is disclosed. The apparatus includes a main frame having a rectangular floor assembly defined by an array of spaced apart, uniformly distributed ball transfer elements and a border formed by raised end rails and side rails. A rectangular interior frame having a length and width less than that of the floor assembly and having a flat floor plate with raised end rails and side rails thereon is movably supported on the ball transfer elements. A first pair of aligned, oppositely coacting fluid cylinders, each being connected between a different interior frame end rail and a corresponding main frame end rail, operates for selective longitudinal movement of the interior frame between main frame end rails. A second pair of aligned, oppositely coacting fluid cylinders, each being connected between a different interior frame side rail and a corresponding main frame side rail, operates for selective transverse movement of the interior frame rails between main frame side rails. The cylinder connections to each of the main frame rails is movable along that rail with parallel movement of the interior frame.
