Abstract

An overhead bridge crane truss having a channel connected to a support beam by vertical connectors is improved in strength by adding wide braces at end regions of the truss, without significantly increasing truss weight or cost. The wide braces are rectangular box beams welded around their upper and lower peripheries respectively to the bottom of the support beam and the top of the channel.
