Monster Truck Trophy or Extreme Heat Caster?

Wednesday, Jun 29, 2016

We like monster trucks - tough, durable, massive - just like Hamilton. So when our Ben Wilson suggested these casters resemble monster truck trophies, we had some fun with PhotoShop.

Hamilton is no stranger to custom engineered solutions so we didn’t flinch when a Pennsylvania distributor presented the following requirements: 1) 25,000 lbs. load capacity per caster, 2) 400° F oven, and 3) suitable for a blast booth environment. The customer also requested rigid casters to minimize the number of moving parts.

So we’ve got a heavy load, high heat, and a nasty environment. Let’s go.

The 25,000 lbs. rated EMD2 high heat casters assembled by Ben Wilson.

Hamilton engineers first selected Hamilton’s Enhanced Maxi-Duty Series (EMD2) platform providing a mounting plate measuring 8-1/2” x 8-1/2”. The EMD2 Series mounting plate is ½” thick and the legs are ¾” thick plate steel.

For the wheels, engineering selected 4140 HT high alloy steel blanks with a tensile strength of 153 KSI. Hamilton CNC-machined the blanks down to a finished size of 10" x 3".

Special composite self-lubricating bearings were then spec’d providing low thermal expansion and low coefficient of friction. The massive wheels and rigs were zinc plated to provide additional corrosion resistance for the extreme environment.

Due to the ever increasing request for high heat applications, Hamilton will be introducing a complete line of standard high heat casters and wheels with diameters ranging from 3” -12” and high heat loads up to 25,000 lbs. The series will feature a new high heat wheel lineup of nylon, silicone rubber, stainless, and forged steel.

Bring the heat! Hamilton can handle it. Contact Jim Lippert with your high heat challenge.
