Cornerstone Engineering & Consulting Expands Aerial Lift & Agriculture Equipment Expert Witness Practice

Licensed mechanical engineer brings nearly 20 years of experience to product liability cases involving boom lifts, scissor lifts, spider lifts, and more.

SPOKANE, WA, October 9, 2026 -- Cornerstone Engineering & Consulting (CEC) today highlighted its expert witness practice, offering attorneys specialized litigation support in aerial lift and agriculture equipment cases. The firm is led by Dax B. Wells, PE, a mechanical engineer with nearly two decades of direct experience designing, testing, and investigating failures in aerial work platforms and agricultural machinery.

Dax Wells has spent his career inside the industries he now testifies about. He has held direct responsibility for engineering, product safety, structural analysis, prototype development, field evaluations, compliance testing, reliability assessments, quality systems, and root cause investigations on complex equipment and manufacturing systems. That background gives him a working knowledge of how these machines are actually designed, built, tested, and used in the field, not just how they look on paper.

His casework has centered on aerial work platform entrapment and tip-over incidents, including matters involving serious injuries and fatalities. In each case, Wells examines how equipment design, operator behavior, machine motion, safety devices, and jobsite conditions come together to produce an incident. That combination of engineering training, industry standards knowledge, and practical field experience allows him to give attorneys a clear, defensible picture of product liability, causation, and defect allegations.

"Attorneys don't need someone who has only read about this equipment," Wells said. "They need someone who has designed it, tested it, operated it, and taken it apart after something went wrong. That's the perspective I bring to every case."

Wells supports both plaintiff and defense counsel, and he is available for early case evaluation, a stage where his industry experience often helps attorneys assess the strength of a case before significant resources are committed. His services include equipment failure analysis, evidence review, case strategy consultation, expert report writing, and testimony.

Wells holds a bachelor's degree in mechanical engineering from Brigham Young University-Idaho and a master's degree in mechanical engineering from the Ira A. Fulton College of Engineering at Brigham Young University, with an emphasis in product design and manufacturing systems. He is a licensed Professional Engineer in Washington State and a trained operator on boom lifts, scissor lifts, and a wide range of construction and agricultural equipment. He is also listed as an inventor on multiple patents, including work related to mobile work platform safety devices.

Beyond litigation support, Cornerstone Engineering & Consulting also provides engineering consulting for manufacturers, covering quality systems, manufacturing optimization, and product design, drawing on Wells' background across boom lifts, scissor lifts, off-road forklifts, agricultural equipment, and other complex equipment categories.
