We have performed extensive work on the various gearboxes supporting material handling on mine sites. Whether the gearbox is for conveying, slurry handling or bulk material handling, we have the experience to improve reliability through our rebuild process.
Hard Rock Drills
United Gear’s mining beginnings included gearbox rebuilds on P&H and CAT hard rock drills. Whether propel, pump drive, rotary, or pulldown we have accumulated the experience to rebuild the key transmissions on P&H 120/320 and BE 49/CAT MD6640 series drills.
