The project consisted of appraising over 200 assets of some of the largest surface mining equipment manufactured by P&H, Komatsu and Caterpillar. Equipment appraised included 400-ton off-highway haul trucks, crawler tractors, blast hole drills, and motor graders along with several large electric wire-rope shovels. With our extensive experience in valuing mining equipment and with our relationships in the industry, we were able to provide accurate and timely information to our clients, helping them make important financial decisions for the future of the company.
