Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest loading conditions. Full box-section rear frame resists torsional shock and twisting forces. Castings in the engine end frame are used in high stress areas to spread high loads. Cast axle pivot mounting areas better disperse stress loads for increased structural integrity. 90 percent of the machine structure is robotically welded to provide highly consistent welds and increased strength.
