Unless you’ve been living under a 50-ton rock, you know about Colossus, Hamilton’s largest and strongest caster ever built. Our engineering team behind the 4.3-foot, 100,000 pound capacity giant recently caught up with Machine Design for a rare look inside the colossal caster.
“Colossus imposes its will from the outside. It’s practically the same height as a pickup truck,” said Ralph Stampfli, Hamilton’s truck team leader. “But inside, that’s where Colossus earns its paycheck.”
Check out the exploded view diagram below for the inside scoop.
- 98 1.5-inch diameter ball bearings ensure smooth rolling
- 18 and 32-inch raceways, flame hardened to boost wear resistance
- An eight-position swivel lock to give operators precise directional control over the 200-ton total payload
