Gray Manufacturing's WD-150S wheel dolly handles super singles and dual wheel assemblies. It accommodates a wide variety of tire and wheel assemblies including truck, aircraft, ground support and farm equipment. Internal bearings provide a smooth rotation of the arms for aligning wheel assemblies to hubs with minimal effort, and the offset column allows for an open work space, improving productivity. The three swivel casters provide great portability when moving wheel assemblies around, and the fore and aft tilt make working on uneven surfaces easy.
