PURPOSE:To relieve labor, to shorten a working time, and to save labor, by a method wherein rollers, placed between guide plates on a road surface and a weight to be moved, are automatically disposed. CONSTITUTION:In a device which moves a weight by traction on rollers, a roller guiding mechanism 1 scoops up, in order, rollers 4 which have been rolled between guide plate 8 laid over a road surface and a weight A to be moved, at the rear lower part of the weight to be moved as a weight A to be moved is moved by traction, and continuously moves the rollers from the rear to the front through both sides. Further, a roller delivering mechanism 12, comprising a cam shaft 14 and an actuating pin 16, intermittently delivers the rollers on the guide plates 8 at the front lower part of the weight to be moved. This enables automatic arrangement of a number of the rollers, and allows to relieve labor, to decrease a working time, and to save labor as much. |
