Abstract
Two- and four-columned stands for holding vehicles aloft during dismantling include A-frame style structures having no raised horizontal cross members. The stands have improved stability and safety for dismantlers and equipment operators in the work area and provide clear access to vehicle components. Preferred stands permit adjustment to the width of the stand at the top. Distance along the length of four-columned stands can be varied to accommodate vehicles of differing lengths, or height of the stand can be adjusted. Four-columned stands include a pair of two-columned stands, each of which is wider at its ground-level base than at the top, and two horizontal ground-level links that connect the two-columned stands at their bases. Preferably a top platform of each two-columned stand includes two horizontal sliding T-beam assemblies that contact portions of a mounted vehicle and also permit width adjustment. T-beam assemblies are mounted on top of diagonal column assemblies and the two resulting structures are firmly attached to opposite ends of a horizontal ground-level base plate. A height adjustment assembly, having a vertical adjustment tube and vertical extendable column, may be incorporated into diagonal column assemblies.
