Description

Technical Field

[0001] The utility model relates to the technical field of pallet trucks, in particular to a multifunctional deformable pallet truck. Background Art

[0002] Under today's advanced logistics methods, the short-distance transportation of scattered goods in the last mile still needs to rely on manpower using small transportation tools. Companies that produce and sell a single category of goods will customize small transportation tools suitable for their own products to complete short-distance transshipment. Nowadays, the Internet logistics model is emerging, which integrates social transportation resources through a sharing model and provides logistics services to individuals, merchants and enterprises. In addition to providing vehicle transportation services, drivers may also need to provide door-to-door delivery services. This is why almost all online-order trucks have to bring their own flatbed trucks.

[0003] Due to the diversity of goods in online-order logistics, it is difficult for drivers to deal with goods of different shapes, weights and materials with just ordinary flatbed trucks. Inappropriate transportation methods can easily cause damage to goods and personal injury. It is not realistic to equip a vehicle with multiple different flatbed trucks. The existing flatbed trucks have a single structure and cannot meet the diverse transportation needs of online-order freight drivers. Multifunctional folding handcarts cannot meet heavy-load needs and are only suitable for the transportation of small items in daily life. Therefore, we proposed a multifunctional deformable flatbed truck to improve the above problems. Utility Model Content
