Description

Technical Field

[0001] The utility model relates to the technical field of manual trailers, in particular to an expandable manual trailer. Background Art

[0002] As a logistics and transportation tool, the definition and use of a manual tow truck vary depending on the scenario and needs. Generally speaking, a manual tow truck primarily refers to vehicles or equipment that require human power to push or pull. They typically lack their own propulsion system but are capable of carrying and transporting cargo or heavy objects. In the logistics field, manual tow trucks are often referred to as manual pallet trucks or manual hydraulic trucks. These vehicles consist of a frame, hydraulic system, and hydraulic handles, making them simple and flexible to operate without requiring an external power source. They are primarily used for loading, unloading, and transporting goods over short distances, such as within warehouses, factories, and construction sites. Furthermore, in the broader context of transportation and transport, manual tow trucks can also refer to various vehicles and equipment that are pushed or pulled by humans, such as agricultural trailers, car / construction vehicle trailers (such as RVs and camper trailers), and road tow trucks. While these vehicles or equipment come in a wide variety and have different functions, they all require human intervention to move them.

[0003] In the existing technology, it is inconvenient to expand the placement space on the trailer when moving the goods that need to be moved in logistics transportation. The placement space on the trailer is a fixed space. If you want to increase the placement space, you need to place a pallet on the trailer that is larger than the placement space on the upper end of the trailer body. After the pallet is placed, there is instability during the movement of the trailer. For this reason, we propose an expandable manual trailer. Utility Model Content
