Abstract
A beam for a bridge crane or conveyor system is extruded from an aluminum alloy in a configuration that disposes thickened regions at four corners of the beam. One pair of these is along opposite edges of a top flange, and another pair is at opposite lower corners of a bottom channel. The thickened regions are formed with alignment pin dowel grooves that can receive dowel pins for aligning butt joints between beams. The thickened regions also contribute to the strength-to-weight ratio of the beam.
