Advantages and Features

POWER & PRODUCTIVITY

  • Cat three-speed planetary powershift transmission and well-known torque divider with free wheel stator put more power to the ground under light load and improve fuel consumption.
  • The Dual Tilt option allows the operator to optimize blade pitch angle, improving load control and making it possible to carry material instead of only pushing it.

OPERATOR COMFORT

  • The suspended undercarriage absorbs impact and reduces shock loads transferred to the undercarriage by up to 50% for a smoother, more comfortable ride.
  • The fully adjustable Cat Comfort Series Seat has thick seat and back cushions to reduce pressure on the back and thighs while allowing unrestricted arm and leg movement.
  • The D9 GC features hand levers with combined steering clutch and brake control for each track.

SAFETY

  • The operator station offers an exceptional viewing area, to give the operator a clear line of sight to front and rear work areas. The low rear window lets the operator see the ripper tip, and single-pane door windows allow clear sight to each side without leaning.
  • Daily power train oil check and sampling ports are easily accessed from the machine platform for convenience and added safety.
  • Ground-level access, retention pins on bottom guard and removed lift cylinder grease points provide a greater level of safety for service personnel.
  • The D9 GC can be equipped from the factory with optional flashing orange beacon and LED lighting for added safety.

VERSATILITY

  • The D9 GC is designed to be used in a variety of applications such as ripping overburden, production dozing, stockpiling, winching, site maintenance, fleet support and reclamation.
  • Application-specific configurations and attachments are available for arctic, desert, heavy construction and steel mill applications.
  • The fully suspended undercarriage provides more ground contact, leading to less slippage and more overall productivity in all applications.
  • The D9 GC’s major components, parts and systems will look familiar to those who have owned, operated and maintained the D9R.

SERVICEABILITY

  • The Cat 3408C engine offers longer fuel and air cleaner life, a new self-tensioner and a single UHE oil filter.
  • The high-efficiency aluminum radiator with hydraulic fan reduces impact damage from debris.
  • Sealed electrical connectors lock out dust and moisture for improved electrical system reliability and servicing.
  • The transmission oil sump is separate from both final drive reservoirs, controlling cross contamination.
  • Time-savers include spin-on fuel and engine oil filters, and fast-fuel and quick oil change attachments.

BLADES & ATTACHMENTS

  • The perfect match for the D9 GC, Cat blades are aggressive in tough materials and offer superior loadability.
  • Cat blades have the ability to resist torsional bending and distortion and offer increase wear resistance without sacrificing machine balance or performance.
  • Blade options include universal, semi-universal, reclamation, coal and cushion.
  • Rear attachments include single-shank ripper, multi-shank ripper, counterweight and winch.
  • The tip and shank protector are easily installed with a 180-degree turn of a ¾-inch ratchet. This simple installation means no hammering, quicker change-outs and less downtime.

BUILT TO GO THE DISTANCE

  • The heavy, strong and durable frame features high-strength steel castings and continuously rolled top and bottom frame rails. Frames provide durable support to the undercarriage, elevated final drives and other components.
  • The mainframe is built to absorb high-impact shock loads and twisting forces encountered during severe dozing and ripping applications.
  • Full box-section frame rails are designed to keep components rigidly aligned.
  • Powertrain and main components are built to be rebuilt — for a cost-effective second life of like-new performance at a fraction-of-new price.

SUPPORT BEYOND THE IRON

  • Like all Cat products, the D9 GC is supported by the global Cat dealer network — a one-of-a-kind, on-the-ground support network that delivers expert service, flexible solutions, after-sales support, fast and efficient parts fulfillment, world-class rebuild and remanufacturing capabilities, and more.
  • Optional Product Link™ transmits basic health, machine location and utilization data for remote machine monitoring via the online VisionLink user interface. Cellular and satellite versions are offered to provide connectivity in remote locations.
  • The Cat App helps sites manage their assets from a smartphone. Users can see fleet location and hours, get critical required maintenance alerts and even request service from their local Cat dealer.

SUSTAINABILITY

  • Features like extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.
  • By rebuilding machines and components, the Cat Rebuild and Cat Reman programs preserve raw materials, conserve energy and reduce emissions.
  • Increased commonality of systems and components, plus a reduction in unique part numbers, reduces waste and lowers owning and operating costs.
