MOVE with MORE RESPONSIBILITY

MOVE with MORE RESPONSIBILITY
Meeting regulations is very important for your business. The D9T is powered by Cat C18 engine with ACERT Technology – which meet today's most stringent emissions standards and are poised to take on tomorrow's challenges as well. Power through tough materials with full rated net power of 436 horsepower at 1,800 rpm.

MOVE with MORE RELIABILITY

MOVE with MORE RELIABILITY
You can't afford to have operators not dozing. Helping you get more done with maximum availability, the D9T's durable design makes repair and maintenance easy. You can rebuild these dozers several times using the same frame with only minor repairs. It's not unusual for a Cat dozer to log more than 100,000 hours. The backbone of the dozer is a heavy, strong and durable frame with high-strength steel castings and continuously rolled top and bottom frame rails. The D9T frame provides durable support to the undercarriage, elevated final drives and other components.

Modular Design

Modular Design
Mechanical availability is one of your top concerns. The D9T reduces downtime by making our machines easy to repair and maintain. Major components are modular in design, so most can be removed and reinstalled without disturbing other systems – which allows the D9T back on the job faster.

MOVE with MORE VERSATILITY

MOVE with MORE VERSATILITY
Every day you are focused on productivity and cost per unit for increased profitability. With the D9T fully suspended undercarriage you will get more cycles per day. Every additional cycle you get because of the smooth ride means increased production and lower cost per unit of material moved. The elevated sprocket and suspended undercarriage work together, increasing traction and giving the operator a smoother ride. The elevated sprocket design transfers implement shock loads to the mainframe, so final drives, axles and steering components are isolated from harsh impacts. These benefits translate into higher production and longer component life.

MOVE with MORE EFFICIENCY

MOVE with MORE EFFICIENCY
Productive operations begin with a productive operator. Noise, stress and fatigue all have an effect on operator performance – so we've designed an environment that helps minimize them. Within the D9T the operator environment is more than a cab; it's an integrated electronic platform designed to maximize productivity. The new Information Display screen is larger, faster and more powerful with increased memory and intuitive menu structure.

MOVE with MORE INTELLIGENCE

MOVE with MORE INTELLIGENCE
You expect advanced solutions for improved uptime and performance. Several electronic features have been integrated into the D9T to help a less skilled operator become better and obtain the most out of the machine to help reduce operator fatigue and get more done at a lower cost per unit of material moved. The D9T has several electronic options including but not limited to:
  • Automated Blade Assist
  • Autocarry
  • Adaptive Load Select
  • Automatic Ripper Control
  • Cat Grade Control 3D
