Each weighs 8,000 pounds and towers 52 inches above factory floors.
Hamilton Caster is well known for making heavy duty industrial casters – and now, one of the biggest. Hamilton recently designed and built four 100,000-pound capacity casters for a federal contractor. Fully assembled, each caster towers 52 inches above the factory floor and weighs more than 8,000 pounds. Together, they represent Hamilton’s highest payload capacity ever: 200 tons.
“Everything about this job was colossal,” said Ralph Stampfli, Hamilton Caster’s truck team leader. “From the springs to the ball bearings. We even had to use a 30-ton crane, 6,000-pound forklift and 3/8th-inch chain just to move it out of our factory.”
Each Colossus caster was designed with a spring-loaded suspension system to absorb shock. The swivel construction consisted of 32” and 18” dia. raceways flame hardened to 55-60 HRC with a total of (96) 1-1/2” dia. bearing balls. Each caster also featured an eight position swivel lock for directional control, a huge 7” diameter oscillating axle to accommodate uneven surfaces, and a foot-operated braking system. The massive payload required 36” diameter by 20” wide extreme duty press-on tires with 4-1/2” dia. tapered roller bearings. Hamilton’s Cart and Trailer division designed and fabricated the integrated towing system weighing over 4500 lbs. for the two front casters.
“This is what Hamilton Caster does,” said Dustin Manz of Service Caster Corporation, the distributor that sold the casters. “They are the best out there as far as custom products go, and we needed that on this project. They really came through in a big way.”
“We’re very proud of Colossus,” said Mark Lippert, vice president of marketing. “It embodies everything Hamilton stands for: innovation, durability, precise engineering, and, of course, Made in America.”
