The Linen Trolley has one, two, three, and four rounds. The wheelbarrow can be driven on narrow ramps, bridges, and paths, can be steered in place, and is very convenient for dumping goods. Commonly used two-wheeled Linen Trolleys include hand trucks for handling bulk items, rack carts, and bucket trucks for handling bulk materials.

There is one in the three-wheeled Linen Trolley and two swivel casters in the four-wheeled trolley (see swivel casters in the figure). This swivel caster can automatically adjust to the direction with the least running resistance along with the change of the moving direction of the vehicle during operation.
Classification
The Linen Trolleys for different purposes have different body structures. Most general-purpose four-wheeled carts have a cargo platform. Special trolleys have various structures, some of which are box-shaped, which are suitable for carrying light-weight and easy-to-load items.
