PURPOSE:To make the moving work safe, by loosening wires, controlling oil pressure, moving tilting arms up or down to face a pile or the like, and moving a base plate rightward or leftward to push the pile or the like by the arms to automatically convey the pile or the like to inclined side rods. CONSTITUTION:When a long article A is to be moved down, wires B are loosened first, and the first shafts 11 of guide rollers 10 are pushed by the piston rods of hydraulic cylinders 12 at both the ends of the long article depending on the direction of the moving-down thereof, so that the shafts 11 are moved in guide holes 24 and the guide rollers 10 are caused to roll on guide surfaces. At that time, tilting arms 8 are moved up so that rollers 7 at the upper ends of the arms face the peripheral portion of the long article A. After that, a base plate 6 is moved by a motor so that the long article is pushed and rolled by the rollers 7 at the tilting arms 8 and is once kept on inclined side rods 35 by the wires B. Every time the long article is kept on the rods 35, the wires B are loosened so that the following long article can be received. The following long article is then moved by a moving device. A single person is thus enabled to perform unloading work safely. |
