You can continue to use the equipment you have been using for a long time.

Advantages of Overhaul

    Experienced service engineers who are familiar with Komatsu NTC equipment will overhaul the equipment.
  2. Planning work tailored to customer requirements
    We stock many of the major components needed for overhaul, so we can tailor the work to your plans.
  3. Same quality assurance as new
    We provide the same quality inspections and quality assurance as for new equipment, so that you can continue to use your equipment as you have used it for a long time.
