Abstract
Abstract In a storage and retrieval arrangement, a rail mounted load carrier is adapted to move up and down aisles formed between spaced bin-type storage frames. The load carrier includes a pair of upstanding masts which rollably engage an overhead rail and a lift platform, carrying a pair of extendible forks, elevatable between the masts. A transfer car is provided to movably transfer the load carrier between the aisles by rolling along rails disposed upon the floor; the floor being at the same level as the floors in the aisles. The transfer car includes a bed having a plurality of load beams which support rollers and a plurality of rails which are adapted to be aligned with the rails of the aisles and receive the load carrier; the load beams and rollers being spaced from each other by a predetermined distance to provide direct support to the load carrier when the load carrier is being transferred. The transfer car is also adapted to simultaneously transfer a pick-up conveyor and delivery conveyor with the load carrier.
