The four-way shuttle elevator is a key equipment for layer changing operations in the shelves of the multi-pass system, and is widely used in the multi-pass system.

[0003] The current four-way shuttle vehicles can move horizontally or vertically, but the supporting elevator can only allow the four-way shuttle vehicle to enter from one side in order to ensure the stability of the lift.
