However, because the lifting height of the manual pallet lift is too low to reach the height of the conveyor line, in automated logistics conveyor lines, it is necessary to transport the goods transported by the manual pallet lifts to the conveyor line.

[0004] For this purpose, we provide a pallet elevator. The reciprocating pallet elevator is often connected to the conveyor to realize the transfer of pallets or goods between different heights, which can greatly improve efficiency and safety. Utility Model Content

The arrangement of other structures inside the lifting frame does not need to avoid the transmission shaft, which improves the compactness of the structure and is beneficial to the stability and standardization of the equipment.

[0041] As a specific implementation, the chain transmission assembly includes two drive sprockets 6, and the drive sprockets 6 are connected to the chain 7; the lower drive sprocket 6 is arranged to be connected with the drive motor 3, and the upper drive sprocket 6 is fixedly mounted on the top of the hoist frame 1 through the driven wheel mounting seat 11, and the lifting module is fixedly connected to the chain 7. Specifically in this embodiment, the drive motor 3 is connected with the reducer 4, and the hoist frame 1 is provided with a mounting seat 5 for fixing the reducer 4, and the lower drive sprocket 6 is connected with the power output shaft of the reducer 4.
