New enhanced Maxi-Duty casters ride low, haul 20 ton
Hamilton’s new addition to its caster lineup handles up to 20 tons and keeps a low profile. The Enhanced Maxi-Duty (EMD2) Series features dual wheel forged steel wheels for heavy manufacturers who need to boost load capacities without increasing overall height. The forged steel wheels are precision CNC-machined with a slight crown for improved rollability and swiveling, then clear-coated for a beautiful pristine appearance. A hybrid of Hamilton’s Maxi-Duty and Ultra Maxi-Duty lines, the new EMD2 series packs a small mounting plate paired with a massive swivel construction. The common mounting plate size (8 ½ by” 8 ½”) makes it easy to swap out existing casters with EMD2. The mounting plate is 5/8” thick joined with a 1” thick swivel base. The legs are ¾” thick and welded continuously inside and outside the swivel base. The main load bearing is an immense 7” diameter thrust ball bearing while the secondary load bearing is a 1-1/4” precision tapered roller bearing to counteract radial thrust. The new series is offered in wheel diameters starting from dual 8” x 3” wheels rated @ 28,000 lbs. up to dual 12” x 4” wheels rated @ 40,000 lbs. Our customers didn’t waste any time enhancing their heavy operations with EMD2. Some of the first models ever built have already been deployed by the Department of Energy.
