Abstract
A beam extruded of aluminum alloy for use in cranes and conveyors is formed with a channel having runs that straddle an open bottom and are strengthened by pin receivers formed in C-shapes with material integrally extruded under the runs. An upper region of the channel is formed with upright parallel fins that serve as a mounting element. T-shaped strengthening upper beam elements can be secured to the channel by sliding them between the parallel fins where they are held in place by fasteners. The upright fins also accommodate a variety of mounting arrangements.
