Small-diameter rollers on these dollies rotate like a conveyor belt around a center plate to distribute weight evenly and provide a smooth ride while moving heavy equipment. They have steel rollers that are rugged but noisy, and can damage floors.

Rubber-padded dollies firmly grip loads without damaging the surface. Diamond-tread dollies have small teeth on the platform that grip the load.

Swivel platforms with lock provide the most controlled turns by locking every 45°.

Optional steering handles help guide dollies around turns.
