Description

Loading and unloading haulage power trolley

technical field

The utility model relates to the technical field of logistics, in particular to a loading, unloading and hauling power-assisted trolley used in logistics.

Background technique

At present, my country's "online shopping" consumption is growing rapidly, and more and more families purchase goods through e-commerce platforms such as "Jingdong" or "Tmall". For online shopping of large-scale commodities, such as large furniture, kitchen and bathroom appliances, TV sets, washing machines, refrigerators, and air conditioners, sellers usually use vans for logistics and distribution. After the online shopping goods arrive at the destination, they are mainly loaded and unloaded by bare hands. In the process of hauling to the elevator entrance (stair entrance), they mainly use small trailers without power assistance and shock absorbing devices. Due to the limited number of moving personnel and the simple handling tools, not only is the labor intensity high and the loading and unloading efficiency is low, but also due to the bumpy road surface, the express personnel often cause bumps and injuries to goods or people during the process of carrying and moving with bare hands. The current truck unloading devices are mainly forklifts and trolleys. Forklifts are large and heavy, which is not conducive to operating in residential areas and cannot be carried on the truck. Therefore, they cannot meet the needs of large-scale express unloading and hauling. To sum up, at present, the commonly used unloading and hauling device in China is a flat trolley, which completely relies on manpower to unload and transfer, which is laborious to use and low in work efficiency.
