Abstract
Material storage frames or rack assemblies in warehouses are set up in long parallel spaced rows which form narrow aisles therebetween. Each rack assembly has vertical columns and horizontal rows of bins for the storage of material. A pair of Z-rails confront each other from opposite sides of each aisle having oppositely extending bottom flanges secured rigidly to the floor and upper flanges extending inwardly of the aisle which form guide tracks with the web of the Z and the floor. Vertical support posts of the rack located adjacent the aisle are spaced longitudinally of the aisle and rest upon the adjacent floor mounted Z-rail flange, whereas the lowermost row of stored material units, usually palletized, are adapted to be supported by the respective upper flange portion of each Z-rail between the pairs of vertical posts or each storage rack. Side mounted guide rollers, such as may be associated with a fending guide plate assembly for vehicles such as lift trucks, are adapted to engage the tracks formed by the confronting Z-rails so that the vehicle travels along the aisle in a restrained system.
