Here are some pics of a Caterpillar 793F Mesabi Radiator in the assembly & pressure testing stages. One of our 4th generation youngsters is having her hand at reinstalling the individual Mesabi radiator tubes into the new rubber grommet seals. After all the individual MESABI radiator tubes are installed the complete radiator assembly is submerged [...]

We spent this first week of June 2026 in Elko, Nv. for the Elko Mining Expo. We exhibited for our first time to get our name out there in the heart of Nevada's mining industry. We started the expo off with the golf tournament on Tuesday at the Ruby View Golf Course which is always [...]

Here are some before & after pics of a stationary heat exchanger assembly. This heat exchanger is used for the crusher at one of the mines.

Here are some progress pics of the Caterpillar 994K Loader Hardnose we're doing a complete overhaul & rebuild to. The twenty five individual aluminum AMOCS radiator cores have been removed, cleaned, repaired & pressure tested before being reinstalled into the hardnose. Once all the radiator cores are installed the system is pressure tested to make [...]
