Founded in 1982, our core mission has remained the same – to be a cost savings alternative supplier to the global mining industry.

Dom-Ex is located in Hibbing, Minnesota, and has an experienced team ready to service your component or equipment needs for mining trucks, dozers, loaders or shovels. Our inventory consists of not only the popular items like engines, transmissions, finals, hydraulic cylinders, differentials and suspensions but also the harder to find items like cabs, decks, radiators, castings, attachments and tires. Our team focuses on the CAT and Komatsu brands, but we also carry inventory for O&K, Hitachi, LeTourneau, Euclid and Bucyrus. 

Over the last 35+ years, our team has created extensive networks and business relationships all over the world. These connections provide our team with insight about idled mining equipment available globally that can be relocated to your mine site. Our relocation services group is able to manage every detail of the equipment relocation process from disassembly and transport to reassembly at your mine site.
