Hamilton UMD Ultra Maxi-Duty Casters

 

Series UMD
Ultra Maxi-Duty Casters

Capacity Range: 17,000 – 40,000 lbs.

The Ultra Maxi-Duty with a load rating up to 40,000 lbs. per caster represents the highest capacity production caster series on the market today. Hamilton engineers started with a clean slate and built this series from the ground up with one task in mind: build the most durable 40,000 lbs. capacity caster possible! The series is designed and built for extremely heavy duty applications such as shipbuilding, military, aerospace, and moving any other immense loads.

The UMD’s swivel design consists of two massive precision thrust ball bearings and a third highly specialized four point contact bearing that provides easy swiveling under extreme loads. The series is offered in both single wheel and dual-wheel versions and all models are backed by Hamilton’s three year product warranty.
