Description

Technical Field

[0001] This utility model belongs to the field of port terminal cargo transfer technology, specifically a port terminal cargo transfer and loading / unloading device. Background Technology

[0002] As vital hubs for international trade, ports and terminals undertake a large volume of cargo transshipment and loading / unloading tasks. With the continuous growth of global trade, the efficiency of cargo transshipment and loading / unloading at ports and terminals has become one of the key factors restricting port development. Cargo transshipment and loading / unloading facilities at ports and terminals are an important component of the port logistics system, directly affecting cargo loading / unloading efficiency, transshipment speed, and overall operating costs.

[0003] For example, Chinese Patent Publication No. CN218316749U discloses a port terminal cargo transfer device, including a box body with baffles inside. Three equally spaced grooves are formed at the bottom of the box's inner cavity. The bottom of the baffles is located inside the grooves, and fixing mechanisms are installed on both sides of the grooves on the surface of the box body. This port terminal cargo transfer device, through the use of baffles, locking blocks, fixing plates, springs, and vertical rods, can divide the internal space of the box body, thereby achieving the purpose of classifying and transferring goods. It also allows users to adjust the position of the baffles according to the size of the goods. However, the transfer vehicle itself has a certain height, making it inconvenient to load some heavier port goods, and the goods are not easily secured during loading, leading to potential detachment and economic losses.
