A hand trolley, also known as a hand truck or dolly, is a simple wheeled device used for transporting heavy or bulky items. It typically features a vertical frame with two wheels at the back and a flat platform or ledge at the front. Users can tilt the trolley backward to lift the load off the ground, making it easier to move items like boxes, furniture, or appliances. Hand trolleys are commonly used in various settings, including warehouses, retail stores, and homes. They come in different sizes and designs, some with additional features like foldable frames or adjustable handles, enhancing their versatility and ease of use.
