Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a sand and gravel transporting trolley. Background Art

[0002] A transport trolley is a handy tool used to move goods and gravel around factories, warehouses and construction sites. It is usually made of a sturdy metal frame and equipped with four wheels to move on smooth surfaces. The design of a transport trolley usually takes into account the weight and volume of the goods to ensure that it can withstand a certain range of loads.

[0003] At present, in order to transport sand and gravel to the appropriate location during construction, a transport cart is usually used to transport sand and gravel. The existing sand and gravel transport carts are not equipped with shock absorbers, and will face challenges in stability and safety after long-term use. Due to the weight and irregular shape of the sand and gravel themselves, the transport carts are easily affected by vibrations and bumps during transportation. The lack of a shock absorber design will cause the vehicle to be unable to effectively alleviate these shocks, which in turn affects the stability and safety of the transport cart, increases the risk of rollover, and has low safety. After long-term use, sand and gravel transport carts without shock absorbers are prone to various damages, such as frame deformation, increased wheel wear, and loose connectors. This will not only affect the handling efficiency, but may also cause safety hazards and increase maintenance and replacement costs. Utility Model Content
