Abstract

A cross-member for a trailer frame and a frame incorporating the same. The cross-member extends between longitudinally aligned rails designed to pivotally support a dumping body thereon. The cross-member includes a cylindrical tube having a wall defining a bore therethrough. A planar member is received within the bore and is axially aligned therewith. The tube includes one or more axially aligned openings proximate a central region thereof. The planar member is disposed intermediate the openings and is aligned axially with the openings. The cross-member is substantially rigid under tension and at least a portion thereof is flexible under torsion.
