Caterpillar introduce new D9 dozer
New 50-tonne dozer designed to reduce owning and operating costs for applications worldwide
THE new 50-tonne Cat D9 dozer replaces the D9T model and offers customizable configurations to meet application needs around the world.
Built on a legacy of longevity and proven reliability in the field, the new Cat D9 is said to lower overall costs per unit of material moved by up to 3%, whilst efficiencies gained through a new torque converter with stator clutch reduce fuel consumption by as much as 5%.
The new dozer features the proven Cat C18 engine, which has a range of exhaust after-treatment solutions available, including configurations to meet US EPA Tier 4 Final/EU Stage V regulations and configurations equivalent to US 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. The suspended undercarriage delivers more track contact with the ground for less slippage and greater productivity.
The new dozer can be equipped with any of a wide range of blades and attachments, allowing it to work efficiently in a variety of applications, including production dozing, site maintenance, fleet support and ripping.
Featuring a frame that absorbs and withstands high-impact shock loads encountered in severe applications such as quarrying, the new D9 offers design improvements that are said to reduce maintenance and repair costs by up to 4%.
The newly integrated AutoLube system reduces daily maintenance procedures, whilst extended filter change intervals, simple component removal and continuous fluid level monitoring also aid in further lowering operating costs.
A new ground-level service center provides convenient access to the engine shutdown switch, access/egress lighting and optional powered ladder operation. With standard rear-view mirrors, the new D9 affords the operator clear lines of sight to front and rear working areas, while an optional four-camera system offers a 360° view around the machine and ripper to further enhance operating safety.
A new design with advanced ergonomics, the cab features intuitive controls that are easy to access and operate. A cloth air-suspension seat provides superior operator comfort, whilst the machine’s suspended undercarriage reduces shock load transfer by as much as 50%, 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) provide customers with crucial information such as location, operating hours and machine condition, as well as production information.
In addition, Automated Blade Assist makes use of preset blade pitch positions for load, carry and spread tasks to increase efficiency and reduce operator workload, whilst the Cat AutoCarry option automates blade lift to maintain desired blade load to improve load consistency, reduce track slippage and increase productivity.
Likewise, optional Automatic Ripper Control maintains ripper depth to limit track slip and allow the operator to focus on the job.
The new D9 will be available in the fourth quarter of 2020.
