Metal dollies– are the most heavy-duty transport dolly but are still easy to handle and can be used for moving a range of containers, pallets, bins and drums. Corner dollies made of steel are available to fit under each corner of a load meaning these can be used for handling various sized and shaped items. Plywood dollies– an often support a larger load capacity or kg of weight than their plastic counterparts and often have a non-slip coating to prevent slipping.

A dolly consists of a flat platform and four casters with plastic or rubber wheels. The frame is often made with steel and the platform from wood, plastic, steel or aluminium. Most commonly the wheels are on swivel castors which swivel 360 degrees to enable the load to be moved in any direction. Plastic dollies– are often made of sturdy ABS plastic or polypropylene which is easy to clean and lightweight for easy manoeuvring. Some of these have interconnecting points so that multiple dollies can be linked together to create a larger platform.
