Caterpillar has launched the new Cat D9 dozer, which replaces the prior D9T model and offers customizable configurations. Built on a legacy of longevity and field reliability, the Cat D9 lowers overall costs per unit of material moved by up to 3%, according to Caterpillar. Efficiencies gained through a new torque converter with stator clutch reduce fuel consumption by as much as 5%, and the new dozer reduces maintenance and repair costs by as much as 4%.
The new dozer features the Cat C18 engine, with a range of exhaust aftertreatment solutions available, including configurations to meet U.S. EPA tier 4 final and EU stage V regulations and configurations equivalent to U.S. EPA tier 2 and tier 3.
The D9 also features differential steering for a tight turning radius and the ability to maintain ground speed while turning to keep productivity high. The suspended undercarriage delivers more track contact with the ground for less slippage and greater productivity.
The D9 can also be equipped with a wide range of blades and attachments, enabling it to work in applications that include production dozing, site maintenance, fleet support and ripping.
With a frame that absorbs and withstands high-impact shock loads, the D9 offers design improvements that reduce maintenance and repair costs. The newly integrated AutoLube system results in fewer grease points to limit daily maintenance procedures. Extended filter change intervals, simple component removal and continuous fluid level monitoring also aid in further lowering operating costs.
A new design with advanced ergonomics, the cab features intuitive controls that are easy to access and operate. The suspended undercarriage reduces shock load transfer by as much as 50% to the undercarriage, resulting in a smoother and more comfortable ride. The new operator station comes fully equipped with large, high-definition touchscreen displays and new electronic architecture that is scalable to meet the customer’s technology needs.
Sensors integrated into the new Cat D9 provide access to advanced operating technology for increased machine productivity. Standard Product Link Elite and Vital Information Management System (VIMS) are powerful machine management tools that provide customers with crucial dozer information like location, operating hours and machine condition as well as production information.
The D9 will be available in the fourth quarter of 2020.
