PURPOSE:To obtain a machine for stacking steel pipes and for forming those into a hexagonal shape by providing substantially vertical and movable stoppers in the front and rear of an elevating frame for carrying steel pipes or the like, by providing a front frame which is replaceable with the stoppers and adapted to be receive the forward sections of the steel pipes in an inclined condition, and by providing a rear frame which is vertically and longitudinally movable and adapted to receive the rear end parts of the steel pipes in the inclined condition. CONSTITUTION:When steel pipes 2 or the like are stacked one upon another in a rectangular shape having the vertical front and rear surfaces, the steel pipes 2 or the like adapted to be stacked on an elevating frame 3 are positioned at their forward end by stoppers 4 which are longitudinally movable. Thereafter, the steel pipes are stacked one upon another in a substantially vertical rectangular shape while they are prevented from being dropped forward. Further, when the steel pipes 2 or the like are formed into a hexagonal shape, front and rear frames 5, 6 position the front and rear ends of the steel pipes while they regulate the inclinations of the front and rear sections of the pipes so that the steel pipes 2 and the like are successively stacked on the elevating frame 3. Thus, it is possible to stack the steel pipes and as well to form the steel pipes into a hexagonal shape by use of one and the same machine.
