PURPOSE: A lifting device for a lifting bed of a car carrier automobile is provided to secure lifetime through preventing the generation of eccentricity while a piston lowered and lower the height of a post and reduce vibration and secure the long lifting distance of a lifting member through the short lowering distance of a piston by using a plurality of rollers. CONSTITUTION: A lifting device for a lifting bed of a car carrier automobile comprises a fixing unit(40), a piston(20), a lifting member(50), a first roller(11), a second roller(12), a third roller(13), and a fourth roller(14). The fixing unit is installed in a post and fixes the end portion of a wire. Wires lift the piston and a lifting member. The piston is lifted by a hydraulic cylinder(30) and installed in the lower portion of the fixing unit. The lifting unit is inserted in a pin hole and an elongated hole and coupled with a pin(51). The pin lifts a lifting bed. The pin hole and the elongated hole are formed in a lifting bed. The first roller and the third roller are installed with space in the piston into horizontal direction. The second roller and the fourth roller are installed in the upper side of the first roller and the third roller. |
