ABSTRACT:
A double reach shuttle assembly for a storage and retrieval machine. Latch mechanisms are provided on the movable elements of the shuttle to control the sequence of extension of the movable elements thereby reducing the amount of space required beneath a load in a storage rack to accommodate the shuttle elements when the double reach shuttle is used in a single reach mode. As the shuttle extends, each movable element remains stationary until the element above it reaches a predetermined point relative thereto. The invention further provides additional latch mechanisms which insure that the load carrying element of the shuttle is the last to retract.
