To provide a suspended cage having a two-wheel structure, which facilitates getting over a snow-resistant ring and a counter weight even when they are attached to an overhead transmission line, improves the workability by weight reduction, secures the visibility of a worker owing to wheel structure miniaturization, and further prevents the generation of noise even when the suspended cage advances forcibly along the overhead transmission line.
Two wheels rolling in a condition in which they are put on the overhead line are longitudinally arranged in the upper part of a frame. A seating part for the worker is suspended in the lower part of the frame. The suspended cage advances along the overhead line when the worker gets in the cage. The suspended cage includes an auxiliary lever forcibly rotating the wheel by using a principle of leverage. Moreover, the auxiliary lever includes a rotating gear coupled to the supporting shaft of the wheel, and a ratchet mechanism unit comprising an operating piece. The wheel can be forcibly rotated to a predetermined direction or can be freely rotated by operating the operating piece.
