Description
Technical Field
[0001] The utility model relates to a loading and unloading device, in particular to a carriage loading and unloading device for long strip goods. Background Art
[0002] When loading cargo onto a train, a manual tractor or forklift is typically used to transport and lift the cargo into the rear of the train. The cargo is then manually stacked piece by piece from the rear of the train into the back of the train, requiring a back-and-forth process of transporting and stacking. When unloading, the process is repeated in reverse. This method of loading and unloading not only results in low container utilization but also inefficiencies.
[0003] For some long strips or long tubes, they usually need to be loaded one by one, which makes them easy to scatter when piled up. Alternatively, they can be bundled first and then loaded into the truck. Either way is time-consuming and labor-intensive, and the efficiency is too low. Summary of the Invention
