Hamilton Maxi-Duty Casters

Series MD
Maxi-Duty Casters

Capacity Range: 3000 – 23,000 lbs.

Move over 10 tons on Hamilton’s top-of-the-line Maxi-Duty Casters, designed and built for the toughest applications including shipbuilding, manufactured housing, automotive and aerospace. Long life and dependable service are assured now more than ever with Hamilton's HPI™ Swivel Technology. The technology is a significant upgrade from conventional ball raceways or unit load bearings and provides an even stronger platform to support Hamilton’s three year product warranty. All forged steel wheels are machined with a slight crown to enhance rollability and swiveling.
