This document discusses refurbishing mining equipment hydraulics using two patented processes: HeyTec 1000 and DURACHROM. HeyTec 1000 involves machining and coating cylinder interiors with aluminum bronze to restore parts classified as unrepairable. DURACHROM coats cylinder exteriors with high-grade steel for corrosion and wear protection. The document provides details on the two processes, results of testing and certification, cost savings versus new parts, and customer testimonials praising their long-lasting results.
