Features

OPERATOR COMFORT AND CONTROL

  • Isolation-mounted, pressurized cab reduces noise and vibration.
  • Large, single pane windows offer excellent views all around the machine for productivity and safety.
  • The Comfort Series seat is offset by 15 degrees for better visibility.
  • Adjustable seat and armrests ensure comfort when working on steep grades or slopes.
  • Display is easy to read, even in direct sunlight.
  • Ergonomically designed controls for low-effort and ease of operation.
  • Decelerator pedal gives full control of engine speed when the rocker switch is in the high idle position.
  • A single-handle control performs steering and gear selection.
  • Tiller bar control allows the operator to work more precisely in close areas around structures, grade stakes and other machines.
  • Differential Steering provides the finest modulation in the industry.

PERFORMANCE AND PRODUCTIVITY

  • Precise controls optimize power and fuel efficiency.
  • Differential steering maintains power to both tracks while turning. When one track speeds up, the other slows down an equal amount. Maneuverability - especially with large blade loads - is improved, as well as cycle times.
  • Unique Cat torque divider sends 70 percent of engine torque through a converter and 30 percent through a direct drive shaft for greater driveline efficiency and higher torque multiplication.
  • Planetary power shift transmission includes three speeds forward and three speeds reverse, featuring thick, large diameter, high capacity, oil-cooled clutches. These clutches provide higher torque capacity and increase service life.
  • Modular transmission and differential slide into rear case for servicing ease, even when a ripper is installed.

BUILT FOR LONG TERM PRODUCTION

  • Rugged frame absorbs high impact shock loads and twisting forces.
  • Dozer pivot shaft runs through the mainframe and connects the roller frame for independent oscillation.
  • Pinned equalizer bar gives the roller frames the ability to oscillate up and down to better match ground contours for maximum traction and operator comfort.
  • Tag-link design mounts the blade closer to the machine for excellent maneuverability, machine balance and blade penetration.
  • Elevated sprocket design optimizes machine balance for best possible performance in each application. And, it keeps machine center of gravity low, offering excellent stability, balance and traction.
  • Ground and implement shock loads are transferred to the mainframe to protect final drives, axles and steering components from harsh impacts for longer life.
  • Modular power train components make it quick to remove and repair the transmission, final drives, steering differential or brakes.
  • Modular undercarriage components simplify service. Lifetime lubricated idlers and track/carrier rollers provide the ability to re-use internal components and rebuild or reshell components, reducing owning and operating costs, and raw materials and natural resources.

TOP-TIER SERVICE AND SUPPORT

  • Modular components, easy access to regular service points and features that enable quicker diagnostics all add up to less maintenance time and more time on the job.
  • Cat machines include sampling ports for the engine oil, power train hydraulics and coolant.
  • Major components on the D7R are built to be rebuilt, extending the useful life of the machine. Rebuilds save money and support sustainability saving raw materials and natural resources.
  • Manage costs with preventive maintenance programs like Custom Track Service, S·O·Sanalysis and guaranteed maintenance contracts. Stay productive with best-in-class parts availability.
  • When it's time for replacement, your Cat dealer can help you with Genuine Cat Remanufactured parts. Remanufactured power train and hydraulic components cost less, but come with the same warranty and reliability as new products.

PURPOSE BUILT SPECIALTY MODELS

  • Waste Handler/LandfillArrangement offers specialized guarding, striker bars and seals help protect the machine from impact and airborne/wrapping debris. Cooling is designed for high debris environments and easy cleanout. Specialized air handling features help deliver cleaner air to the machine. Landfill blades and center-hole track shoes help optimize your waste handler for the job.
  • Cold Weather package features reversible fan and heavy-duty battery/alternator for cold starting. Arctic cab has dual pane glass. Oils and final drive seals are designed tostand up to cold conditions.
  • Stockpile arrangement helps protect both the machine and the operator in high debris conditions. Features turbine precleaner, solid hood and a cooling system designed for reduced plugging and easier clean-out.
