Best built for the toughest conditions.

Robust Structures

Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest loading conditions.

  • Full box-section rear frame resists torsional shock and twisting forces.
  • Castings in the engine end frame are used in high stress areas to spread high loads.
  • Cast axle pivot mounting areas better disperse stress loads for increased structural integrity.
  • 90 percent of the machine structure is robotically welded to provide highly consistent welds and increased strength.


Your key to maximum uptime and productivity is our purpose built front and rear frames.

  • Full box-section frames absorb torsional forces during dozing, maintaining alignment for hitch pins and drive line.
  • Spread hitch design features double tapered roller bearings and hardened pins that resist both horizontal and vertical loads.
  • Enhance strength in key pin areas through the use of one piece castings.

Push Beam and Push Arm Dozer Arrangement

To ensure long life and reliability, solid one piece push beams are through-width, not merely attached to the side of the frame. In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.

Power Train

Move material more efficiently with improved power and control.

Steering and Transmission Integrated Control System (STIC™)

Experience maximum responsiveness and control with STIC that combines directional selection, gear selection and steering into a single lever.

  • Simple side-to-side motion turns machine right or left, minimizing operator movements.
  • Easy to operate finger controlled gear selection.
  • Smoother, faster cycles and less operator fatigue through the use of low effort integrated controls.

Cat Planetary Powershift Transmission

Building your success begins with a best-in-class transmission designed specifically for mining applications.

  • Consistent, smooth shifting and efficiency through integrated electronic controls.
  • Long life and reliability through heat treat gear and metallurgy.
  • Three forward and three reverse speeds to match your application.

Cat C32 ACERT Engine

Durability and efficiency at the heart of your 854K comes from the Cat C32 engine with ACERT technology. Optimum performance is built in through the use of a 12?cylinder, four-stroke design.

  • On-demand performance through the use of turbochargers and aftercoolers.
  • High Torque Rise - 33% torque rise ensures high lugging forces during dozing.
  • Extended engine life through lower rpm ratings.
  • Quick engine response through the use of electronic engine controls.
  • U.S. EPA Tier 4 Final rating available for highly regulated regions.

Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS)

Lower your cost per ton utilizing advanced ICTC and RCS for modulated rimpull.

  • Reduce tire slippage and wear by modulating rimpull from 100 to 25 percent while depressing left pedal. After 25 percent rimpull is achieved the left pedal applies the brake.
  • Reduce the potential for wheel slippage without reducing hydraulic efficiency with RCS.
  • Improve fuel efficiency in certain applications with our lock-up clutch torque converter providing direct drive.
