Extra Heavy AGV/Continuous Duty Casters
Capacity Range: 3200 – 15,400 lbs.
With a max capacity of 15,000 lbs. per caster, this series is built from the ground up to withstand the non-stop punishment of 24/7 operation for extra-large AGV’s and other material handling equipment.
Hamilton accomplishes this feat by leveraging proven HPI swivel technology, premium low heat polyurethanes, forged steel wheel cores, and extra large precision ball bearings.
HPI® swivel technology was created years ago in response to an AGV application. HPI® outperforms conventional CNC-machined ball raceways, kingpinless and unit load bearing swivel constructions.
Hamilton engineers then selected two of our 1” thick polyurethane treads—Ergo-Glide XT and DuraGlide—for their easy rolling, quiet operation and overall stellar performance.
For added durability and to accommodate larger precision ball bearings with extended bearing-life, the wheel cores of the 3”, 4” and 5” wide wheels in the series were upgraded from cast iron to forged steel. Our engineers then designed press-fit top hat spanner bushings to eliminate axial play and reduce noise.
The end result is an extra heavy duty caster series designed for years of continuous operation and trouble-free performance. Series offers both single wheel (MD, EPSD) and dual wheel (MDD) models; select dual wheel models to gain stability and higher capacities.
