Productivity

Load-sensing hydraulic steering system, which helps operators achieve precise positioning for easy loading in tight areas with 43 degrees of steering articulation.
Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS), which improve rimpull and reduce tire slippage and wear and improve fuel efficiency in certain applications.
Cat Planetary Powershift Transmission for consistent, smooth shifting and efficiency through integrated electronic controls, with three forward and three reverse speeds
Steering and Transmission Integrated Control System (STIC™), which combines directional selection, gear selection and steering into a single lever — for maximum responsiveness and control.
Cat C32B engine that delivers on-demand performance through the use of turbochargers and aftercoolers, with a 33% torque rise that ensures high lugging forces during digging and acceleration in high rimpull conditions.

Serviceability

Reduced time spent on regular maintenance procedures thanks to features such as ground-level or platform access to filters, grouped service points and swing-out doors on both sides of the engine compartment.
Standard VIMS™ 3G monitoring system with easy-to-view display that delivers critical health and payload information, keeping performance at optimum levels and allowing advanced troubleshooting and planning to lower maintenance costs.
Extended performance and reliability thanks to advanced filtration system.

Durability

Full box-section frames that absorb torsional forces during dozing, maintaining alignment for hitch pins and drive line.
Spread hitch design featuring double tapered roller bearings and hardened pins that resist both horizontal and vertical loads.
Enhanced strength in key pin areas through the use of one-piece castings, and solid one-piece push beams that are through-width, not merely attached to the side of the frame.
90 percent of the machine structure is robotically welded to provide highly consistent welds and increased strength.
Frame, powertrain, engine and components that all built to be rebuilt — using new, remanufactured or rebuilt parts and components — to deliver multiple lives of like-new performance at a fraction-of-new price.

Technology

Cat MineStar™ Terrain for loading, which provides real-time feedback on payloads and design plan progress to increases productivity and accuracy, reduce rework, enhance ore control and improve shift-to-shift operator performance.
MineStar Detect, with offers a range of capabilities designed to assist the operator with areas of limited visibility around fixed and mobile equipment.
MineStar Health, which delivers critical event-based machine condition and operating data and includes comprehensive equipment health and asset monitoring capabilities, with a wide range of diagnostic, analytic and reporting tools.
Upgraded touchscreen information display that provides intuitive operation and easy navigation and keeps operators informed about machine systems to decrease service time.

Sustainability

Designed to be more efficient and use less fuel, which reduces engine emissions and carbon footprint; Tier 4 Final engine reduces NOx and particulate matter.
Engine Idle Shutdown, which saves fuel by making it possible to avoid unnecessary idling.
Reduced waste with maintenance-free or extended-maintenance batteries, and better control of fluids through use of ecology drains.
Retrofits and upgrades for older machines — to incorporate efficiency improvements and emission reductions, and to keep them in production longer to conserve energy and minimize the need for raw materials
Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions.
