The Cross Country 453TSDX is a 45-foot tridem side dump configured for tridrive tractors working heavy off-road and resource haul routes. Larger 6-inch lift cylinders and an A-frame pedestal support structure give it the muscle and stability to cycle dense material on uneven ground. The Hardox 450 wear-plate tub and 100,000 psi hi-tensile steel frame are built for continuous duty in the harshest conditions.
