ABSTRACT:
A conveyor arrangement, as associated with a storage rack, employs a plurality of individual load-supporting trolleys or pads supported on sloped runway segments which are activated by a cyclically-actuated vertical lifting arrangement, with this arrangement being supported within a rail or frame structure having supporting flanges for the loads. When the lifting device is activated to lift the inclined runway segments and pads upwardly, the loads are lifted away from the supporting flanges, whereby the weight of the loads causes the pads to move downwardly by gravity along the sloped runway segments to forwardly advance the loads a small amount, until the loads again contact the support flanges. When the pads are lowered due to lowering of the lifting arrangement, the pads are biased back to a raised position along the upper end of the runway segments whereby they are again engaged under the load to permit repeat of the cycle.
