Abstract
Overhead crane apparatus is disclosed incorporating an extruded aluminum alloy rail structure for runway and bridge girder applications. The relatively light weight and low cost rail structure is shaped to provide a trolley passageway protected from the ingress of deleterious substances, and is further contoured to provide a shaped cavity for ready reception of novel clamp means facilitating the imposition of increased loads on existing crane apparatus. The rail structure during the extrusion process may also be formed with fluid passages in the side walls thereof.
