ABSTRACT:
An upper endless rail has a downwardly opened guide channel, and a lower endless rail has an upwardly opened guide channel. A plurality of circulatory frames are mounted for movement along and between the upper and lower endless rails. Each circulatory frame has a plurality of casters mounted at a lower side portion thereof and positioned in the guide channel of the lower endless rail and further has a plurality of upper guide rollers mounted at an upper side portion thereof for contacting with and rolling on a side face or faces of and in the guide channel of the upper endless rail. Each caster includes a support roller for rolling on an inner bottom face of the guide channel of the lower endless rail and a lower guide roller for contacting with and rolling on an inner side face or faces of the guide channel. Each circulatory frame is moved with the load thereof supported by the support rollers of the casters from below while rocking motion of a lower portion of the circulatory frame is prevented by the lower guide rollers. The weight of the circulatory frames does not act upon the upper endless rail at all.
