Mobile. Agile. Versatile.
Cat Wheel Dozers are designed with durability built in, ensuring maximum availability through multiple life cycles. With optimized performance and simplified serviceability, our machines allow you to move more material efficiently and safely at a lower cost per ton. Engineered for your demanding work in large dozing applications, the 844K Wheel Dozer is the largest in the Cat Wheel Dozer line and is an ideal match for large mining operations, power generating utilities, the general contracting industry and wherever mobility, versatility and compaction is needed.
ROBUST STRUCTURESYour 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.FRAMESYour key to maximum uptime and productivity is our purpose built front and rear frames.Full box-section frames absorb torsional forces during dozing, maintaining alignment for hitch pins and drive line.Spread hitch design features double tapered roller bearings and hardened pins that resist both horizontal and vertical loads.Enhance strength in key pin areas through the use of one piece castings.PUSH BEAM AND PUSH ARM DOZER ARRANGEMENTTo ensure long life and reliability, solid one piece push beams are through-width, not merely attached to the side of the frame. In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.
