[0002] A cart is a transport vehicle that is pushed and pulled by manpower. At a construction site, a large amount of building materials such as sand, gravel and bricks need to be transported by carts. However, as workers push and pull the carts to transport materials, the efficiency of the workers pushing and pulling the carts to transport materials will gradually decrease (due to factors such as the workers' physical strength and the site terrain). Therefore, a cart that is convenient for transporting materials is needed to improve the transportation efficiency of materials. Utility Model Content
