PURPOSE:To improve processing speed by installing an elavation-arm supporting board installed onto a supporting rack base which can freely travel along rails, in retreatable ways in the perpendicular direction to the rails, in the captioned apparatus in which hangers for suspending treated articles are transported between plating tanks, etc. CONSTITUTION:A traveling motor 4 which can be revolved in the normal and reverse directions is fixed onto a supporting rack 3 which can travel freely through wheels 8 on two rails 9, and the rotary force of the motor 4 is transmitted through gears 5 and 7 to a rotary shaft 6 equipped with wheels 8 at both edges. On the supporting rack base 3, a hydraulic cylinder 10 is arranged and fixed in the perpendicular direction to the direction of arrangement of the rails 9, and a supporting board 12 is fixed onto the edge part of the piston 11 of the cylinder 10. An elevation motor 13 is fixed onto the supporting board 12, and a chain 15 whose one edge is fixed onto a balance weight 17 accommodated into a guide cylinder 16 fixed onto the supporting board 12 is laid onto a chain wheel 14 installed at the edge of the output shaft of the motor 13, and an elevation arm 19 which can be elevated along a guide cylinder 16 is fixed onto the other edge of the chain 15. |
