Double Wheels Heavy Duty Construction Wheelbarrow

The unicycle uses the lever principle to close the resistance point of the load to the fulcrum (i.e., the wheel) to make its operation efficient, and also shares the load on the unicycle and the operator. Because unicycle makes it easy to move heavy or large loads, it is indispensable in construction sites, agricultural land and gardens.

Although the two wheeled handcart is relatively stable on the flat ground, the unicycle has high operability in places prone to imbalance, such as small, planked or raised roads, and is easier to control when unloading.

The wheelbarrow is commonly known as "handcart", also known as a chariot, a deer cart, a handcart, a handcart, a dirt cart, a sheep's head cart, a sheep's horn cart, etc. In the Western Han Dynasty, it appeared on some field passes. The name of wheelbarrow officially appeared in the Northern Song Dynasty. [4] Before the popularization of modern means of transportation, it was a light vehicle for carrying goods and people. Especially in the north, it played almost the same role as the donkey.
