ABSTRACT:
A base for a storage and retrieval machine is disclosed in which the frame of the base comprises a pair of spaced apart frame members having a length generally parallel to the rail upon which the base travels and extending a portion of the length of the base. The frame members are positioned straddling the rail with the rail projecting upward into the space between the frame members. A mast is mounted on the base and supports a vertically movable carriage means for carrying objects to and from overhead locations. The pair of frame members may comprise a pair of L-shaped members each having a downwardly projecting upper wall spaced apart from the upper wall of the other L-shaped member and a lower wall projecting away from the lower wall of the other L-shaped member in a direction laterally of the length of the base. The base includes first and second trucks located at opposite ends of the pair of L-shaped members. A wheel is rotatably mounted on each truck and both wheels engage the rail for supporting the storage and retrieval machine as it travels along the rail. The trucks have a height sufficient to support the wheels, however, the L-shaped member pair are positioned at a lower height than the height of the first and second trucks to permit the low height profile of the base. An anti-tip bracket is affixed to a foundation adjacent the path of travel of the base, typically at the end of an aisle in which the rail is located. A lower wall of one of the L-shaped sections engages the anti-tip bracket to hold the storage and retrieval machine from tipping.
