PURPOSE:To make possible to attach readily an insulating cover to an existing conductor bar, by forming a conductor bar of a trolley by covering the conductor with an insulating cover whose underside is open, and dividing the cover into two. CONSTITUTION:The bar (A) of a trolley includes the conductor 1 covered with the insulating cover 2 whose underside is open and which is divided longitudinally into halves (a, b) that are clamped by a clamping member 3 and are secured by a bolt and nut 4 thereby facilitating the attachment of the insulating cover 2 to the existing conductor 1. On the other hand, the body of a collector (B) is attached in a floated state on a base 8 comprising an insulator through a coil spring, small wheels 16 of suspending members 12 attached to opposite sides of the base 8 are supported on rails 17 provided on opposite outer surfaces of the insulating cover 2, and the collector (B) will be travelled with it suspended from the bar (A). |
