A flanged link cross tube (1) for use in pivotal connections of beams (10) that locates weld roots (5) to the outer mating surface of beam (10) and flange (4). As the beams (10) rotate about a pivot connection, high torque loading occurs along the common plane (Z) between adjacent beams (10). Locating weld roots (5) on the outer mating surface of beams (10) and flanges (4) reduces loading on weld roots (5) and extends the useful life of a scissors lift (20).
[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.]1. A linkage assembly, comprising:a first tube;a second tube;a first cross tube extending through the first tube and having a first radially-extending annular flange at one end connected to a side of the first tube;a second cross tube extending through the second tube; anda pivot pin extending through the first cross tube and the second cross tube, the first radially-extending annular flange being located between the first and second tub...
