<p>PURPOSE:To prevent cargo working articles in a cage from falling by always engaging the upper portion of the cage with a guide roller at the time of traveling while joining this case to a supporting board which is being engaged by the two points of a front roller and a following roller by means of a cross link. CONSTITUTION:By joining a chain to a driving bogie 3, as this chain is pulled to drive the driving bogie which is engaged with an outside rail 1, cages 7 also travel in an engaged condition with an inside transferring rail 2 accompanying the travel of the driving bogie. In this case, since a supporting board 4 forming a part of the driving bogie is engaged with the outside rail by means of a front roller 5 and a following roller 6, the length direction of the bogie is conformed to the length direction of the outside rail in a traveling position. Further, since the cage 7 is engaged with the inside rail 2 by means of one guide roller 8 while being rotatably installed on the driving bogie by means of a cross link 10, the cage 7 will not be swung centering around the guide roller 8. As a result, cargo working articles in the cage can be prevented from falling.</p> |
