A rail system and transfer vehicle for a storage retrieval system. The rails are fabricated to include a vehicle support surface that supports a transfer vehicle, a load support surface that supports the skid, tote, vessel, or pallet to be stored, a spacing surface that defines the distance between the load support surface and the vehicle support surface. Attached to the load support surface is an alignment surface that extends upwardly at an angle between 40 and 80 from the horizontal. When a misaligned pallet is lowered, it first contacts the alignment surface and as it continues to be lowered, interaction between the alignment surface and the misaligned pallet causes the pallet to move into alignment with the rail system before coming to rest on the load support surface. The rail system can be used in conjunction with a high weight capacity transfer vehicle. Load lift is provided by a plurality of interconnected screw jacks. The screw jacks can be raised, lowered, and precisely controlled by an inverter duty AC gear motor connected to the jacks by a sprocket/chain system.

[ We claim:] [1.] A precision placement storage and retrieval system comprising:(a) a pair of parallel elongated rails defining a storage lane, each rail being the mirror image of the other, each rail having a wheel support surface, a spacing member, a load support surface having an exterior edge disposed away from said storage lane, and an alignment member, said support surfaces being substantially parallel to each other and fixedly connected to said spacing member so that said spacing member is disposed away from said storage lane and said load support surface is disposed above said wheel support surface, said alignment member being fixedly attached to said exterior edge of said load support surface and extending upwardly at 40-80 degrees from a plane defined by said load support surface;(b) a transfer vehicle having a bottom, a transport system comprising a plurality of wheels attached to axles, a drive wheel motor, and a lifting mechanism, said axles and said motor supported by said vehicle bottom, said axles being rotationally controlled by said drive wheel motors, said transfer vehicle being supported by and moveable in said storage lane by the interaction of said wheels and said wheel support surfaces of said rails; and(c) load supporting apparatus having a plurality of flat bottomed runners, said runners being sized to fit on said load support surfaces between said alignment members so that if said runners contact said alignment members, said runners slide down said alignment members until said runners rest on said load support surfaces.
