In the mode of transporting building materials, water transportation is often more economical than land transportation, and the transportation volume is big, so the constructor can use the transport ship to transport the materials to the construction site, and then use manpower to transport the materials ashore. Tasks such as grit transportation are born by the handcart basically, but when the handcart went on and off the ship, all walked on marine springboard, and the springboard often has the antislip strip for antiskid, and this makes the handcart appear beating when traveling on the springboard, makes user's difficult control balance and direction, and the condition of the water of falling still appears crossing in the workman that the quality of health is relatively poor. In this case the customer has multiple choices of two-wheeled carts, which are easier to control and balance than single-wheeled carts.

Moreover, it has been found in commercial communication that carts suitable for local workers should be lighter in weight and smaller in size, as carts designed for the east asian population tend to be heavier when fully loaded, and local people would like to be able to reduce weight and size.

Thus, if a single-wheeled cart is designed to accommodate shipping and transportation, and preferably be lightweight, simple in construction, easy to maintain, and easily retrofit, it would be possible to achieve the same broader market and customer preference as a two-wheeled cart.
