General purpose hand trucks are upright wheeled carts that let one person move large or heavy loads, such as boxes, crates, bins, equipment, and raw materials. Also known as dollies, hand trollies, or stack trucks, hand trucks have a nose plate that supports a load and a vertical frame that prevents the load from falling off the trucks as they are moving. The nose plate slides under the load or the load is stacked onto the nose plate, and the trucks are tilted back and balanced on their wheels so they can be rolled from one place to another.
