Advanced MEUI™-C Injector
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
All Cat engines feature innovative air-management systems that optimize airflow and enhance power, efficiency and reliability.
Cat NOx Reduction System (NRS)
The NRS captures and cools a small quantity of exhaust gas, then routes it back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
The aftertreatment solution utilized for Tier 4 Final/Stage IV products is the next evolutionary step for Cat engines with ACERT Technology. To meet the additional 80% reduction in NOx emissions required by Tier 4 Final/Stage IV emission standards, Caterpillar engineers only needed to add one new system to the already proven aftertreatment solution in use, Selective Catalytic Reduction (SCR).
Diesel Exhaust Fluid (DEF)
Cat engines equipped with a Selective Catalytic Reduction (SCR) system inject Diesel Exhaust Fluid (DEF) into the exhaust to reduce NOx emissions. DEF is a precisely mixed solution of 32.5% high purity chemical grade urea and 67.5% de-ionized water.
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.
- Speed hold/limiting function allows the machine speed to be limited in 1 km/h or 1 mph steps to conform to site speed restrictions.
- Gearshifts have been significantly improved to maintain direct drive lock-up, and eliminate dropping into converter drive. Reducing the use of torque converter drive helps maintain ground speed and gradeability.
- Variable shift points used based on the operating conditions, which also aid in maintaining ground speed during gear changes on grades.
- Critical gearshifts maintain direct drive lock-up, and eliminate dropping into converter drive. This maintains ground speed during shifts on grades.
- The transmission automatically modifies shift points to best suit operating conditions and performance.
- Retarding levels are automatically reduced on lesser grades in lower gears.
Large capacity torque converter, configured for off‑highway applications, allows the higher engine power to be transmitted more efficiently to the lower power train.
Engine Compression Brake
Improves retarding response and increases retarding power.
Automatic Traction Control (ATC)
Application of the inter and cross-axle differential locks is ‘on-the-go’ and fully automatic. The operator does not have to think about when and where to engage either the inter or cross-axle differential lock. Sensors monitor the machine and wheel speeds, enabling instant response in low traction conditions. Operation is seamless and smooth, eliminating wheel slip for maximum traction and productivity.
Clutches are also automatically disengaged when not required, eliminating any impact on machine maneuverability, such as making a tight turn at the top of a grade.
The ATC system helps reduce tire and driveline abuse, eliminating lost efficiency caused by improper manual operation of the differential clutches, and reducing the cost of premature tire replacement.
When set to automatic, regeneration will occur without any interaction from the operator. The three modes of regeneration shown below allow the articulated truck to adapt to specific site conditions in the most efficient manner.
Automatic: The machine carries out “on-the-go” regeneration when the engine control module determines conditions are acceptable. The operator requires no action and the articulated truck is not required to stop working.
Automatic: Low idle regeneration is initiated when the machine is in a reduced operating mode for a predetermined period of time, and a number of conditions are met. The system is designed so that the operator can interrupt regeneration at any time.
Manual: A manual regeneration is initiated by pressing the regeneration switch for five seconds. The machine must be brought to a non-operating mode in order to perform a manual regeneration.
All three axles have oscillating a-frames with lateral tie rods, controlling sideways movement of the axle and providing stability. In conjunction with suspension system, it allows the operator to travel at speed over rough terrain and softens impact loads on structures and components.
Large bore, low-pressure cylinders are purpose designed for off-road applications and offer a soft, smooth ride for the operator. The front suspension oscillates ±6° to assist in providing a smooth ride. Suspension mounting points are integrated into the axle housing, increasing reliability.
Comprising of a walking beam and Caterpillar designed long life rear suspension mounts; the rear suspension system provides a reliable and stable ride for excellent travel over rough terrain and aids load retention.
All Axle Enclosed Wet Brakes
Introduced for the first time on this model, the oil-immersed system is a multi-disc, multi-plate design. Enclosing the brakes prevents the ingress of contaminants. This protects the system, extends life, and reduces replacement costs while improving machine uptime.
The three-point front suspension with its oscillating axle and low‑pressure ride struts, combined with the center-mounted cab, offer unrivaled levels of ride comfort for the operator in all driving conditions. The operator remains comfortable and productive throughout the day.
Spacious Two-Person Cab
The large two-person cab, offers a comfortable working space for both the operator and a passenger. The passenger seat is fully padded with a backrest and a wide, retractable seat belt for a secure and comfortable ride. It is also positioned adjacent to the operator, giving both the operator and passenger a clear view of the instrument panel, controls and the road. The storage space behind the operator seat has been increased, and access improved the design and layout is common across all C Series Articulated Trucks.
Air Suspension Seat
The air suspension seat provides improved operator comfort with a cushioned upper high back, adjustable damping with three settings, ride zone indicator and adjustable lumbar settings. It is fully adjustable to provide the optimal driving position.
The air conditioning system keeps the in-cab temperature however the operator likes it, whatever environment they are operating in.
Optional Four-Point Seat Belt
Offering greater restraint and potentially better safety for operators, the four-point operator seat belt is now available as an option. The seat belt is part of an entire new seating arrangement, not solely an addition to the existing seat.
The cab is designed to make all aspects of machine operation as simple as possible. The controls and gauges are easy to read and straightforward to operate, allowing the operator to focus on safe machine operation while maintaining productivity.
The integrated wrap-around dash puts all controls within easy reach of the operator. Featuring LED illuminated rocker switches for the dash dimmer, rear wash wiper, hazard warning, work lamp, secondary steer, A/C and cigar lighter. Delivers an automotive feel with the industrial strength you would expect from Caterpillar.
Color Multi Purpose Display (CMPD)
The dash mounted display unit shows the operator various levels of performance and condition pages as well as machine warning categories. These include performance data, configuration settings, operator and machine totals, service information, various machine status parameters, machine payload information (when fitted), and the video feed from the rearview camera.
Bluetooth™ Stereo Connectivity
Make and receive calls in cab via the optional, Bluetooth equipped, radio entertainment system.
The front frame design features a large box section and wide, stiff frame beams to handle torque loads. The divergent frame design decreases stress in the hitch area and optimizes suspension geometry. The frame design makes maximum use of robotic welding for increased durability.
Twin-box construction minimizes stress concentrations and provides low weight with long service life.
The three-point oscillating axle front suspension provides unparalleled ride quality. It also protects the truck from adverse road conditions by absorbing shock loads that would reach the frame.
The articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain.
Field proven two-piece construction features a durable cast steel head bolted to a hard wearing forged steel tube.
Dump Body Design
All C Series machines have a large target area to provide consistently high load-carrying capacity. Its diverging flow design gives clean material discharge, which maximizes production and avoids the waste of carry-back.
Output Transfer Gear
Distributes drive to the tractor and trailer and includes a wet clutch differential lock for optimum traction in poor underfoot conditions.
Dual-circuit, all wheel braking system. The full power hydraulic system actuates enclosed, oil immersed, multi disc, multi plate brakes with independent front and rear circuits and accumulators.
