PROBLEM TO BE SOLVED: To provide insulated trolley wire current collecting equipment in which a current collector piece can be received and seated surely and stably in the groove of a destination insulated trolley wire when the current collector moves among a plurality of insulated trolley wires. SOLUTION: The insulated trolley wire current collecting equipment supplies electricity to a moving load F by sliding a current collector 1 being fixed to the moving load F on an insulated trolley wire 2 being fixed to a building material Z. The current collector 1 comprises a current collector piece 11 sliding on the insulated trolley wire 2, a rotary seat 3 on the side of the current collector 1 receiving a shaft 30 provided in the current collector piece 11, a rotary seat 4 on the side of the load F receiving a shaft 40 provided in the load F, and an arm 5 having the opposite ends coupled rotatably with the rotary seat 3 on the current collector 1 side and the rotary seat 4 on the load F side, respectively. The insulated trolley wire current collecting equipment is further provided with a rotation suppressing portion 6 having a spring piece 60 abutting resiliently from the opposite sides of the arm 5 and preventing the arm 5 and the rotary seat 4 on the load F side from rotating about the shaft 40 provided in the load F.
