PURPOSE:To assure correct supply of a shock absorber in a noise preventing equipment for materials to be transferred such as steel tubes or the like, by providing the traction means of a shock absorber having a truck with a surface to be abutted against the bottom surface of the shock absorber and by constructing it so that the traction means swivels to engage with the shock absorber as the state of abutment changes due to movement of the traction means. CONSTITUTION:A chain 1 rotates in the direction as indicated by the arrow to move a traction means 15 which comes in close contact with the chain 1 at the first position 15a. As the traction means is moved, the contact state of the means is changed and at the point 15b a hook 18 comes to nearly engage with a stopper 17 due to the bend of chain 1 there. Then, since an abutting section 16 is abutted against the bottom surface 14B of a shock absorber 14 at this moment, the hook 18 can not engage with it. When the traction means 15 is further moved, the hook 18 engages with the stopper 17 at the position 15c to lift up the shock absorber 14 therewith until it rotates reversely. After the reverse rotaton, the hook is released from the stopper 17 by its own weight, whereby the shock absorber 14 moves by itself to strike against a material to be conveyed and stops. By this constitution, correct supply of a shock absorber is assured without a need of any device for cutting out a shock absorber. |
