Benefits and Features

DESIGN PHILOSOPHY: CAT LARGE DOZERS

  • Ensure productivity in all applications
  • Keep operators safe, comfortable and in control
  • Take advantage of technology
  • Make them easy to maintain and repair
  • Make them last

High productivity no matter the application:

Elevated sprocket and suspended undercarriage work together:

  • Increases traction, giving the operator a smooth ride in all conditions
  • Makes component removal easy for quick repair times
  • Elevated sprocket transfers implement shock loads to mainframe, isolating final drives, axles and steering components from harsh impact

Applications

  • RIPPING OVERBURDEN
  • PRODUCTION DOZING
  • RECLAMATION
  • WINCHING
  • FLEET SUPPORT
  • SITE MAINTENANCE
  • STOCKPILING

PERFORMANCE & EFFICIENCY ENHANCEMENTS

  • Torque converter with stator clutch—high efficiency, less fuel
  • Bogie suspension—less slippage, more production
  • Differential steering—large loads, fast and smooth maneuvering

LESS SLIPPAGE. MORE PRODUCTION

The D9 features Bogie Suspension, which allows the track to conform to ground condition, providing more ground contact, especially in hard, uneven terrain. Higher traction means less slippage, better balance and a smoother ride.

LARGE LOADS. SMOOTH MANEUVERING.

The D9 features differential steering, so large blade loads can be smoothly maneuvered throughout a turn. Differential provides a tight turning radius and maintains a high ground speed while turning to keep productivity high. The planetary powershift transmission controls permit smooth speed and direction changes with Advanced Productivity Electronic Control System (APECS).

Torque converter with stator clutch

1) Automatically frees up stator when torque multiplication is not required under low load, resulting in:
–Higher drivetrain efficiency
–Less fuel consumption

2) Locks automatically during higher loads and retarding

3) No noticeable changes felt by operator
