Engine
Every Tier 4 Final/Stage IV 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.
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.
Automatic Features
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 tractio...
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.
Operator Environment
Ride Comfort 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.
Ease of Operation
Control Layout 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.
Durability and Reliability
Front Frame 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.
Cat CONNECT Technology
Cat CONNECT makes smart use of technology and services to improve your job site efficiency. Using the data from technology-equipped machines, you'll get more information and insight into your equipment and operations than ever before.
Serviceability
Long Service Intervals Changes to oil change intervals, volumes and the type of oil required will help lower maintenance costs and machine downtime.
Complete Customer Support
Selection Make comparisons of the machines you are considering before you buy. Your Cat dealer can help.
Sustainability
All Cat Articulated Trucks are designed to maximize efficiency and productivity while conserving natural resources.
Safety
Product Safety Caterpillar has been, and continues to be proactive in developing machines that meet or exceed safety standards. Safety is an integral part of all machines and system designs.
