Abstract: The invention is directed to a conveyor assembly for use in conveying a load from a first device or member to a second device or member. The conveyor assembly has a frame with a pair of frame support members spaced from each other in an essentially parallel manner. A pair of belts are provided proximate the frame support members, with each belt having a wide portion and a narrow portion. The wide portions of the belts cooperate with surfaces of the frame support members when the belts are in a first position. The wide portions of the belt cooperate with a container such that as the belt is moved from the first position to the second position, the container is moved accordingly. The narrow portion allows a transport assembly to be moved into and out of the conveyor assembly, whereby the configuration of the belt allows the conveyor assembly to be used for containers which are more narrow than the transport assembly, thereby effectively providing the transport assembly with an effectively smaller width.

Abstract: 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.
