Cat D9 dozer surfaces

A new torque converter, new steering, new cab design and new servicing features are among some improvements Caterpillar has made to the new D9 dozer.

It will replace the D9T model and lowers overall costs per unit of material moved by up to three per cent, according to Cat.

A new torque converter with stator clutch reduces fuel consumption by up to five per cent, and new servicing features reduce maintenance and repair costs by as much as four per cent, Cat added.

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/EU Stage V regulations and configurations equivalent to U.S. EPA Tier 2 and Tier 3.

It comes with differential steering for a tight turning radius and the ability to maintain ground speed while turning for better productivity. The suspended undercarriage delivers more track contact with the ground for less slippage.

The D9 can be equipped with a wide range of blades and attachments to carry out many applications including production dozing, site maintenance, fleet support and ripping.

The D9 features a frame that absorbs and withstands high-impact shock loads encountered in severe applications, Cat said.

A newly integrated AutoLube system has fewer grease points for fewer daily maintenance procedures. Filter change intervals has also been extended and continuous fluid level monitoring aids 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.

Standard rear view mirrors and an optional four-camera system offer a 360-degree view around the machine and ripper for enhanced operating safety.

The cab has been redesigned to offer advanced ergonomics and controls to operators. 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.

The suspended undercarriage reduces shock load transfer by as much as 50 per cent to the undercarriage, Cat claimed, resulting in a smoother and more comfortable ride.

The new Cat D9 is equipped with sensors that work with advanced technologies to offer increased machine productivity.

An Automated Blade Assist function makes use of preset blade pitch positions for load, carry and spread tasks to increase efficiency and reduce operator workload. The Cat AutoCarry option automates blade lift to maintain desired blade load for improved load consistency and less track slippage. Optional Automatic Ripper Control maintains ripper depth to limit track slip.

Standard Product Link Elite and Vital Information Management System (VIMS) are machine management tools available with the D9 that provide customers with crucial dozer operating information such as location, operating hours and machine condition.
