Abstract
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).
