A dolly is a low mobile platform that rolls on casters, used for transporting heavy loads. They come in an assortment of shapes and sizes and can have 4 wheels, two wheels or one. They are also made of different materials dependent on the load they are destined to carry. Some dollies have a solid base to support the load and some offer no base at all. Once the heavy weight is placed on the dolly it will make manoeuvring the object much easier.
