Built to Perform

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 that utilize Advanced Productivity Electronic Control Strategy (APECS).
  • Long life and reliability through heat treat gear and metallurgy.
  • Four forward and four reverse speeds to match your application.

Cat C7.1 Engine

The Cat C7.1 engine is designed for maximum fuel efficiency and increased power density. Two engine options are available to meet the emission standards for Tier 4/Stage IV or Brazil MAR-1 and China Nonroad Stage III, equivalent to Tier 3/Stage IIIA.

The Tier 4 Final configuration:

  • Engine is equipped with a Selective Catalytic Reduction (SCR) system which injects DEF into the exhaust to reduce NOx emissions.
  • Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes in back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
  • While in operation, the aftertreatment will be seamless to the operator thanks to the passive regeneration system which is utilized.

Move More with Less Fuel

Improved Hydraulic Efficiency

  • New implement and steering variable displacement load sensing piston pumps.
  • Hydraulic flow now on demand, for improved fuel efficiency.

Cat C7.1 Engine

The Cat C7.1 engine is designed for maximum fuel efficiency and increased power density.

  • Features innovative Cat electronics, fuel injection process, air-management systems and aftertreatment solution (for Tier 4 Final) with Cat Selective Catalytic Reduction.
  • Innovative systems effectively lower the average working engine speed and reduce overall system heat loads for improved performance and fuel efficiency.
  • Deep system integration amongst engine and emissions system, power train, hydraulic and cooling system result in lower fuel consumptions on average compared to the previous model.

Cat Planetary Powershift Transmission

Featuring all new Advanced Productivity Electronic Control Strategy (APECS) transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.

Safety First

We are constantly introducing features on our machines in an effort to enhance safety for the operator.

Machine Access

Steering and Transmission Integrated Control System (STIC™)

Enter and exit the cab easily and safely with a new fold up STIC armrest.

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 help reduce operator fatigue through the use of low effort integrated controls.

Integrated Cat® Technologies

Integrated electronics provide flexible levels of information to both the site and the operator. This integration creates a smart machine and more informed operator, maximizing the productivity of both.

Information Display

We have worked hard to help our customers and operators perform at their best through our newly upgraded touch screen information display.
