A dolly is a platform with four wheels and two axles that can be used to transport heavy items from one location to the next. It features a flat platform and is larger than a hand truck, making it suitable for moving bulkier and heavier items such as boxes, furniture, pianos, luggage, or even small vehicles. Unlike hand trucks, items must be physically placed onto the platform of a dolly. Dollies are available in various designs and sizes, and they are easy to maneuver and ensure that the transported items remain balanced.
