Heyl & Patterson offers a wide array of Services to support all of your needs after purchase of any piece of equipment for the remainder of its operational life. From visual, mechanical and structural inspections to complete field service and engineering studies, Heyl & Patterson has what you need to keep your operations running smoothly.


At Heyl & Patterson, we understand how costly a breakdown can be. That’s why we offer a complete array of inspection services designed to keep you running at peak performance. From visual, mechanical and structural inspections to electrical evaluations, our qualified inspections team can help keep your equipment and your operations running efficiently.

We take the time to review your previous inspections and document the current conditions of components for adjustment, maintenance, monitoring and/or replacement. Our comprehensive inspection program uses a four-part process for all inspection and includes:

  1. A review of your inspection history and maintenance program with a listing of recommended spares in your inventory, including problems and concerns you may have.
  2. An in-depth visual inspection of mechanical components and structural integrity, with emphasis on critical adjustments and key components. We can also perform an engineering study to determine what upgrade options are available.
  3. Observation of normal operating conditions to pinpoint any issues of concern and recommend required tune-ups.
  4. A handwritten report that outlines the inspection evaluations, with a more formal follow-up report that clearly and concisely explains what was inspected, with any problem and supporting recommendation to correct specific problems.

If necessary, a complete engineering study can be performed after the inspection, to compare current operating realities with the original design of the equipment.
