The objective of the present invention is to provide an insulated trolley comprising higher construction ability with a comparatively simple structure. The insulated trolley (30) comprises a tightening device (10), a first connection block (11), a second connection block (12) and a bypass wire. In the tightening device (10), a base part (1) maintains a first end part (21a) of a first insulated trolley wire (21), and an insulator part (2) maintains a second end part (22a) of a second insulated trolley wire (22), and an elastic force is given to the insulator part (2). The bypass wire electrically connects the first insulated trolley wire (21) maintaining a third end part (21b) in the first connection block (11) and the second insulated trolley wire (22) maintaining a fourth end part (22b) in the second connection block (12) electrically. The base part (1) and the first connection block (11) are fixed to a first plane (23aa) of a rail (23). The second connection block (12) is configured to be movable along a length direction of the rail (23). The bypass wire is arranged along a second plane of the rail (23). |
