ABSTRACT:
Telescoping rigid frame/scissor conveyors with suspension structures to accommodate less than totally flat surfaces, and for easy and ergonomic repositioning. Such conveyors are formed of a plurality of telescoping frame segments which may be positioned at any number of desired nested/unnested configurations. The frame segments bear a lazy tong or scissors conveyor structure which assures uniform roller spacing, and rollers positioned at one height along the conveyor rather than at different heights for each frame segment. The conveyors are adapted to bear greater weight than conventional lazy tongs conveyors, but contain suspension systems in order to conform to irregularities in factory and warehouse floors and slabs and for easy movement. The suspension systems may include motorized drive units, swivel mounted roller units, jacking roller units and more conventional rigid legs that contain springs or other suspension members to distribute the loads of and borne by the conveyors evenly and efficiently, and to allow the conveyors to positioned, expanded and retracted easily and efficiently.
