For those who have purchased the Standard Auto Dolly and now find that they need the higher weight capacities and easier rolling of the Heavy Duty Auto Dolly, we now have available a Caster Upgrade Kit. These are the same three bearing, non-marring polyurethane casters found on the Heavy Duty Auto Dolly. Simply remove your original standard casters and bolt these on.
The big difference between the Standard and Heavy Duty Auto Dolly is in the caster type and size. The Heavy Duty Auto Dolly Casters are larger in diameter and outfitted with three beefy sets of bearings: One on the swivel and two on the axle. All of this adds up to three advantages over standard casters:
- It takes less force to get things moving and keep them moving.
- The larger diameter wheels also handle expansion joints better than the smaller ones.
- Greater weight capacities than standard Auto Dolly sets: 10,000 lbs vs 6,000 lbs.
The Heavy Duty casters share the Standard casters' same non-marring polyurethane wheel material that won't mark-up or peel your floor like steel wheels will.
