For maneuverability in tight spaces, these dollies have two platforms that swivel independently. Their casters are often called triple-swivel casters or zero-throw casters. Ball bearings between the platforms on these dollies allow you to turn and position the load without any caster movement. The top platform has slots for permanent mounting (fasteners not included).

Polyurethane wheels combine the abrasion resistance of plastic with the shock- and sound-absorbing qualities of rubber. They are nonmarking. Use them on smooth or rough floors and in areas with debris.

Neoprene wheels won't degrade when they come into contact with oil, acids, and solvents. They’re resilient and absorb shocks, but not as much as polyurethane rubber wheels. Use them on smooth or rough floors.

Maneuver machines and heavy loads into confined spaces. These dollies have rollers that swivel independently, allowing movement in any direction. Rubber pads in the center grip loads without damaging the load surface. Handles on the dolly make them easier to pick up.

Able to turn on a dime, these casters have two separate swivels in their mounting plate to give vehicles the tightest turning radius. Dual swivels also require less effort to start pushing when the wheels are misaligned. They are often used on automated guided vehicles to prevent a vehicle from jogging off a wire path while turning either 90° or 180°. Their wheels have a steel core for added strength and polyurethane tread with the abrasion resistance of plastic and the shock-absorbing qualities for rubber. Use them on smooth or rough floors. The ball bearings on the wheel and swivel are shielded for protection from dust and debris.
