Hamilton Casters Series MDD

Maxi-Duty Dual Wheel Casters

Capacity Range: 5,000 - 15,600 lbs.

Series: MDD

This dual-wheel series version of the Maxi-Duty Caster addresses the problem of how to restrict overall height while at the same time provide adequate carrying capacity on resilient tread wheels. Dual Wheel Casters also improve stability and swivel more easily than wider-face single wheels because differential action reduces the “scrubbing” effect of soft treads against the floors.

The series still touts its “precision” feature indicating that both the secondary thrust bearing and the main load bearing are precision-made, and yet the new HPI™ Swivel Technology is now a standard feature in this dual wheel series providing smoother swiveling and longer life.
