[0021] During the warehousing operation, the palletized goods 5 enter the lifting equipment 3 via the external conveyor 2. The lifting platform rises and lifts the goods to the corresponding shelf height. The lifting platform conveyor is aligned with the power station conveyor 1. The palletized goods are transported out of the lifting machine via the power station conveyor line 1 or the four-way vehicle 4, and then transported to the shelf position by the four-way vehicle 4.

[0022] During the outbound picking operation, the elevator 3 rises to the picking level upon instruction, aligns the lifting platform conveyor with the power station conveyor 1, and the four-way vehicle 4 removes the goods from the shelf and directly delivers the goods to the corresponding position on the elevator 3 platform via itself or via the power station conveyor 1. The elevator 3 platform then descends to the bottom level, and the goods are transported to the external conveyor 2 by the elevator 3 platform conveyor, completing the outbound operation.

[0023] When a four-way vehicle or cargo is being moved to a different shelf level, the four-way vehicle 4 moves to the entrance of the shelf-changing elevator 3. The four-way vehicle 4 then calibrates to determine the position of the loading platform of the elevator 3. After the calibration is successful, the four-way vehicle 4 enters the elevator 3. The platform of the elevator 3 rises / falls, lifting the four-way vehicle 4 to the corresponding shelf level. The platform track of the elevator 3 is aligned with the track of the power station 1. After the calibration is completed, the four-way vehicle 4 exits the elevator 3 to perform the remaining tasks.

[0024] Palletized cargo 5 is transported by four-way vehicle 4 to power station conveyor 1. After hoist 3 reaches the floor change height, power station conveyor 1 transports palletized cargo 5 into hoist 3. Hoist 3 rises / falls to the target floor. Hoist 3 aligns with power station conveyor 1 and transports palletized cargo 5 into power station conveyor 1. Subsequently, four-way vehicle 4 transports palletized cargo 5 to perform other remaining tasks.
