What We Do

True third-party valuators, our veteran Irontrax team has worked in the construction, mining, transportation and agricultural industries for decades. Appraising such machinery is our core business. Learn more about our machinery and equipment appraisal services and see our additional services below.

Residual Analysis

The best way to mitigate risk is to do a residual forecast. This determines the future value of an asset at a given time.

Floor Plans/Field Audits

Irontrax’s random spot-checks of rental company fleets help clients mitigate risk. Our veteran inspectors don’t just identify and confirm the assets our clients are loaning money against actually exist.

Lease End Inspections/Recovery

Irontrax is widely recognized for its thorough lease end compliance process. We verify that the machinery meets or exceeds documentation benchmarks, guaranteeing customers will collect all the damages they’re entitled to receive.


Irontrax is not affiliated with an auction house. As a trusted independent resource, we’re better able to focus our attention on risk mitigation when selling or remarketing recovered assets.



Machinery and Equipment Appraisals

Our Appraisers have their Accredited Senior Appraiser (ASA) Designation form the American Society of Appraisers.

Those transacting

Estate planning
Mergers and acquisitions

Irontrax professionals have first-hand technical perspectives on heavy equipment, from rebuilding engines to driving semis. Highly-experienced liquidators, we can catch what unqualified appraisers often miss: new vs. old machinery, missing elements, excess mileage, worn out undercarriages, etc.

Our firm is uniquely qualified to understand the risk management side too, thanks to first-hand asset management experience within the financial industry. We understand the machinery and the valuation methodology necessary to help customers most efficiently manage their heavy equipment portfolios, offering the best of both worlds.
