Like a jungle cat, these custom casters are powerfully coiled and travel low to the ground


Monday, November 06, 2017

You’ve heard of keeping a low profile? Well consider this custom job one of our stealthier power trips. When a huge energy company in Canada needed to swap a heat exchange pump in one of their nuclear reactors, they turned to Hamilton engineers to custom design a special set of casters each rated to carry 16,000 lbs. The kicker was that the casters also had to meet incredibly low height restrictions.
 
To swap out the pump, the material handling engineers incorporated a special track system. One side of the casters rode on a track while the other side rode on inverted c-channel to make the exchange. And here’s where things get interesting. The c-channel limited the total width of the caster at the wheel height to 6 ½ inches, so we designed special recessed hardware to get the casters to clear the small channel. Kind of like putting a girdle on when you want to look your skinniest. To meet the low height restrictions and high load requirement, we used a high strength steel for the wheels and tapped our new Maxi-Duty Kingpinless casters with swivel construction.
 
Who says we can’t roar into tight spaces?
