The present invention is applicable to a wide range of general handling of conveyed products, not limited to the engine assembly.

[Effect of device]

As described in detail above, according to the lifting device removing device of the present invention, the movement of the chuck means for removing the lifting device of the conveyor from the lifting device of the one-point suspended conveyed object in the horizontal plane is the movement of the moving frame and the movement. Since the movement of the chuck means itself with respect to the frame requires only two sets of runners for engaging the two sets of rails, the guide mechanism has a very compact structure. The effect that can be obtained is obtained. Further, the chucking means is in a floating state after the gripping operation of the suspension fitting by the chucking pawl. Therefore, when, for example, a case where an engine or the like is hung and conveyed, when a conveyed object that is conveyed with an inclined conveying posture is transferred to a temporary receiving table that is movable in a horizontal plane In addition, after the suspending metal is gripped by the chucking means, the transported object is placed on the temporary receiving table while changing its stable posture.However, since the chucking means is in the floating state, the transported object is transported. There is an advantage that the posture of the object can be freely moved, and the transferred object can be smoothly transferred.
