Abstract
A stacker-retriever lift carriage is disposed to be raised, lowered and positioned, in selected positions with respect to a pair of spaced support masts, by a flexible wire cable connected between a lift drive and the lift carriage. The lift carriage carries a telescoping shuttle which includes a shuttle base, middle table and top table disposed one atop the other and for movement with respect to each either in a bi-directional manner. A pair of sheaves are rotatably mounted on the middle table at an acute angle to the surface of the middle table. A pair of cable connect the sheaves to the shuttle base and top table so that drive of the middle table, by table drive means, in a particular direction effects a movement of the top table in a corresponding direction but at twice the relative distance of the middle table. The middle table is fabricated from a pair of identically sized and formed table plates; has a pair of flaps bent therefrom to an acute angle with respect to a top surface of the table plate. The table plates are affixed together in back to back relationship and with their respective flaps aligned to form the mounting for the sheaves.
