In the case of a three-phase power supply, three insulating trolleys are used. Stretched. Normally, the insulating trolley is stretched so as to be along a predetermined line (not to be bent) by being supported by a hanger 53 as shown in FIG. 5 every 3 to 6 m, and the hanger 53 extends along the runway. It is attached by a bracket. For the bracket, an L-shaped steel (angle) or the like is used, a hole is formed for attaching a hanger, and the bracket is fixed to the runway by welding at a construction site.
