A wheelbarrow is a small, hand-propelled vehicle, usually with one wheel, designed to transport heavy loads. It consists of a rectangular or "U"-shaped bed mounted on a wheel and frame, and two handles at the rear for pushing or pulling. The bed of the wheelbarrow is typically made of wood or metal, and the wheel is usually made of rubber or metal. Wheelbarrows are used for a variety of tasks, such as transporting soil, gravel, mulch, or other materials. They are also commonly used in construction, gardening, and landscaping.
The earliest wheelbarrows were invented in China during the Han Dynasty (206 BCE - 220 CE). They were originally used for transporting goods, but quickly spread to other parts of the world and were adopted for use in a variety of applications. Today, wheelbarrows are an essential tool for anyone who needs to move heavy loads from one place to another.
