RIGID TROLLEY WIRE AND METHOD FOR LAYING SAME

摘要

A rigid trolley rail having a continuous unified structural body which is formed by continuously laying a plurality of short trolley rail bodies made of aluminum along the track of a travelling body and by mechanically connecting or welding confronting ends of adjacent trolley rail bodies to each other. Each of the plurality of aluminum trolley rail bodies consists of a base part attached to fixed support parts, a protruding middle part formed to protrude from the middle portion of the upper or lower face of the base part approximately into a T-shape; and a pair of protruding clamping strips positioned with the protruding middle part interposed between them. A long single sheet of stainless steel is bent to cover the protruding middle parts of the aligned rail bodies to form the continuous unified structural body and the ends of the two bent sides thereof are fixed in a gripping manner by bending the pair of protruding clamping strips inwardly to clamp the bent sides against the base part.
