Caterpillar says its new D10 dozer is designed for greater efficiency through improved technology, longer component life and easier serviceability, all leading to a lower cost of ownership. 

The 155,000-lb. Cat D10 dozer features a stator clutch torque converter and load-sensing hydraulics, making it up to 6% more efficient than the Cat D10T2, with maintenance and repair costs reduced by up to 8%.

Powered by the 602-hp Cat C27 engine, which offers aftertreatment solutions to meet U.S. EPA Tier 4 Final/EU Stage V, as well as Tier 2 equivalent emissions standards for meeting the needs of the global market, the D10 maximizes material moved per liter of fuel. The C27 switches power settings based on travel direction to offer up to 20% more power in reverse, reducing cycle times.

In addition to delivering productivity gains of up to 3%, the new D10 offers up to a 4% fuel consumption advantage over the D10T2 and up to 10% over the D10T.

The dozer’s new torque converter design with stator clutch automatically frees up the stator when torque multiplication is not required, improving drivetrain efficiency for reduced fuel consumption. During high-load and retarding conditions, the stator clutch locks without the need for operator input. Load-sensing hydraulics deliver more power to the ground for increased responsiveness and added fuel efficiency.

The new cab for the D10 not only creates a comfortable operating environment that lowers noise, vibration, stress and fatigue, it is an integrated electronic platform designed to maximize productivity. The operator’s new multicolor touchscreen display monitors machine performance and allows machine parameters to be quickly tailored to the application.

Standard with dual-tilt and Automated Blade Assist (ABA), the machine reduces operator workload by automating blade movement to preset load, carry and spread

positions. In addition, the dozer is customizable to site conditions with multiple optional technologies designed to increase productivity and efficiency, including:

  • AutoCarry, which provides automatic blade control during the carry segment
  • Cat Grade Control 3D that precisely positions the blade’s cutting edge for consistent grades
  • Automatic Ripper Control to minimize track slip by automatically monitoring and adjusting engine speed and ripper shank depth

Shipped from the factory capable of integrating Cat MineStar technologies, the D10 optimizes grading efficiency and offers remote operating capabilities to keep the operator safe and comfortable. MineStar Terrain with Automatic Blade Control integrates full automatics, blade load and overcut protection into the control system to increase productivity and decrease fuel burn. It minimizes overcut, overfill and rehandling to lower costs.

Major components for the D10, including the frame and powertrain, are built to be rebuilt using new, remanufactured or used parts and components to deliver a cost-effective second life of like-new performance at a fraction of the price, according to Cat. Life-enhancing upgrades made throughout the drivetrain help to improve component life.

Optional Heavy-Duty Extended Life (HDXL) with DuraLink Undercarriage reduces scallop wear, features an 8,000-hour bushing seal life and delivers 20-40% longer life than the heavy-duty undercarriage.

The D10 design offers easy service and maintenance with features like new replaceable push-arm trunnion bearing inserts, so the dozer spends less time in the shop and more time dozing. The reengineered engine compartment integrates a single-plane cooling system that is up to 30% more resistant to plugging and improves heat dissipation to extend component life.
