OVERVIEW

FEATURES AT A GLANCE

Engine

Every Tier 2/Stage II equivalent Cat engine with ACERT Technology is equipped with a combination of proven electronic, fuel, air and aftertreatment components. The right technologies fine-tuned for the right applications result in:

High machine performance across a variety of applications.
Enhanced reliability through commonality and simplicity of design.
Maximized uptime and reduced cost with world‑class support from the Cat dealer network.
Durable designs with long life to overhaul.
Delivering better fuel economy with minimized maintenance costs while providing the same great power and response.

Advanced MEUI-C injector platforms deliver increased injection pressures and more precise fuel rates. These durable injectors enhance responsiveness while controlling soot. All Cat engines feature innovative air-management systems that optimize airflow and enhance power, efficiency and reliability.

Transmission

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. Improves retarding response and increases retarding power.

Automatic Features

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.

Suspension and Braking

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. 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.

Operator Environment

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. 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. 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. 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.

Ease of Operation

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. 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. Make and receive calls in cab via the optional, Bluetooth equipped, radio entertainment system.

Durability and Reliability

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. 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. 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. Located on the center axle in an elevated position, it is spring applied and hydraulically released.

Cat CONNECT Technology
