Product Overview
Originally designed for a customer who needs to move an oversized load, the Super Duty Dolly is a specially reinforced version of our 16" dolly that also features SIX high-capacity casters.
Like all of our casters for the Auto Dolly, the standard caster contains a mark-resistant polyolefin wheel that also features a crown profile. The crown profile wheel means less rolling resistance in contact with the ground. The wheel profile also helps to pinch small debris out of the path, rather than to cause the wheels to come to a screeching halt.
Like the entire line of the Auto Dolly, the Super Duty Dolly is made of super-strong 1/4" steel, not flimsy stamped steel. Unlike the Standard and Heavy Duty Dolly, the Super Duty Dolly is given an extra layer of strength and two more casters. This means that an individual Super Duty Dolly has a weight capacity of a whopping 4000 lbs. (8000 lbs. per pair, 16,000 lbs. per set of 4)
