Every Tier 2/Stage II equivalent Cat engine is equipped with a combination of proven electronic, fuel, air and aftertreatment components.
Proven electronic, fuel, air and aftertreament components for peak performance and longevity.
Emissions control and improved fuel economy.
Advanced MEUI-C injector platforms deliver increased injection pressures and more precise fuel rates. These durable injectors enhance responsiveness while controlling soot.
Innovative air management optimizes airflow, power, efficiency and reliability.
The Cat CX31 six-speed forward, single speed reverse transmission features Advanced Productivity Electronic Control Strategy (APECS) and Electronic Clutch Pressure Control (ECPC) which deliver smooth gear changes with improved acceleration and higher productivity.
Large capacity torque converter, configured for off-highway applications, allows the higher engine power to be transmitted more efficiently to the lower power train.
The engine compression brake improves retarding response and increases retarding power.

Advanced Automatic Traction Control (AATC) engages inter and cross-axle differential locks on-the-go giving the operator optimum traction as conditions change.
Clutches release automatically to avoid conflict during tight turns.
AATC reduces tire and driveline wear, eliminating lost efficiency that can occur with improper manual operation.
The new ejector body eject/retract switch initiates automated control of machine systems to stop machine travel and eject the loaded material at proper rpm.
Hill Assist automatically engages the service brakes if the operator removes his foot from the brake pedal while on a grade reducing potential "roll-back ."
The waiting brake system automatically applies the service brakes when the neutral gear is selected, allowing easy control of machine functions at the load or dump area.

Cat Product Link wirelessly connect you to your equipment, giving you valuable insight into how your machine or fleet is performing. The system tracks location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink user interface so you can make timely, fact-based decisions to maximize efficiency, improve productivity, and lower costs.
Cat Production Measurement brings payload weighing to the cab to help optimize job site efficiency and productivity. Operators can view real-time load weights on the integrated display and know precisely when target is achieved, while cab-mounted external payload lights on all four corners signal the loader operator when to stop, reducing the risk of machine overloading. Operators can track daily productivity from the cab, with quick access to truck payload weights, loads and cycle counts, and daily totals; or remotely via LINK technologies.
Cat Detect with Stability Assist warns the operator if machine is approaching a pre-set angle during operation; when driving and tipping. If using the assisted hoist, the machine will stop hoisting the body and give an audible and visual warning. The system monitors angles of tractor, trailer and grade independently. This increases operator awareness of machine stability during operation. All tractor and/or trailer rollover events are logged and reported via VisionLink.
