PURPOSE:To lighten load burden of a weight material by providing movable saddles capable of moving up and down on both sides of a moving beam separately from the moving beam, and elevating the movable saddles to transfer the weight material to a fixed saddle of the moving beam. CONSTITUTION:A weight material 15 is transferred from a transport car 10 onto a movable saddle 14. A moving beam 1 is moved to the right by a cylinder 6, and movable saddles 14 are positioned on both sides of the moving beam 1. Subsequently, a cylinder 4 is driven to lift up the moving beam 1, so that the weight material 15 is made same level with the movable saddles 7, 14. Then, the movable saddles 14, 7 are lowered by a cylinder 13 to support the weight material 15 on a saddle 5 of the moving beam 1. Subsequently, the cylinder 6 is driven to push the moving beam 1 to the next movable saddle 7, and the weight material is supported by the raised movable saddle 7. The moving beam 1 is lowered to be returned to its initial position. By repetition of such operation, the load burden of a weight material can be lightened.
