824 Wheel Dozer

824 Wheel Dozer

DESCRIPTION

Cat® wheel dozers combine the power of a track dozer with the mobility of a wheeled machine to deliver high production at low operating costs in a variety of applications — from surface mining cleanup to coal stock piling, road maintenance to reclamation.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 support your job site efficiently and safely while lowering owning and operating costs. The 824 continues our legacy of reliability, performance, safety, operator comfort, serviceability, and efficiency.

Unmatched Durability

        
  • Solid through-width push beams transfer and absorb stresses through a larger portion of the frame. 
  •     
  • The full box-section rear frame resists torsional shock and twisting forces.
  •     
  • Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.
  •     
  • Optimized axle mounting results in increased structural integrity.
  •     
  • Delayed Engine Shutdown, allows your machine to cool before shutting down the engine to prevent engine and aftertreatment damage.
  •     
  • Resilient, durable blades are designed with excellent dozing and rolling characteristics.
