GONDOLA FOR DOUBLE CONDUCTOR

PROBLEM TO BE SOLVED: To reduce tractive force, and to obtain smooth movement when riding over accessories, by supporting three or more running wheels arranged on a circumferential orbit, in such a way as to be movable far and near to the revolution axis of a revolving mechanism respectively, and to be restorable automatically in outward directions, and reducing vertical movement of the revolution axis by backward movement of the running wheels. SOLUTION: On the revolution orbit of a revolving mechanism 5, four running wheels 4 are arranged at 90 deg. intervals. The revolving mechanism 5 is approximately in an X shape, and four radial arms 8 stretching from a radial revolution axis 7 are provided circumferentially at 90 deg. intervals. The running wheels 4 are provided with supporting shafts 10 for supporting themselves, and the supporting shafts 10 of the running wheels 4 are inserted into the four arms 8 respectively, with compression-type springs between in such a way as to be slidable. Accordingly, the running wheels 4 become movable along the radial directions far and near to the revolution axis 7. Besides, they are energized with the springs along outward radial direction from the revolution axis 7 by the compressive repulsive forces of the springs 9, and are automatically restored onto the fixed revolution orbit.
