PROBLEM TO BE SOLVED: To provide a cantilever type heavy object transfer device which can be supplied at a comparatively low cost with a simple structure, and can simply correct the positional deviation of a heavy object with the bending of a suspension arm to facilitate human operation.SOLUTION: A heavy object transfer device is equipped with a movable base frame 1; a base frame portion 4 which is raised at one end portion of the base frame 1 and supports a lifting driving portion 3; and a suspension arm 5 which is attached to a lifting member 6 installed on the lifting driving portion 3, extends in a longitudinal direction of the base frame 1, and suspends a heavy object to be transferred. The suspension arm 5 is journaled to the lifting member 6, and an end surface cam 10 and rotation driving means 14 are installed on the lifting member 6. A roller 12 which is a follower of the end surface cam 10 is attached to the suspension arm 5, thereby pivotally moving the suspension arm 5 with rotations of the end surface cam 10.SELECTED DRAWING: Figure 1 |
