730C2 Three Axle Articulated Truck

730C2 Articulated Truck

Overview

The Cat 730C2, with a 17 m3 (23 yd3) 28 tonnes (31 tons) capacity, offers demonstrated reliability and durability, high performance and productivity, superior operator comfort and lower operating costs. Updating the successful 730C to include all axle enclosed wet brakes makes the 730C2 a more attractive proposition for our customers. Class leading levels of performance and operator comfort make for a productive machine all day long.

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.
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.
  • Maximized uptime and reduced cost with world-class support from the Cat dealer network.
  • Minimized impact of emission systems: designed to be transparent to the operator without requiring interaction.
  • 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 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.
Aftertreatment Technologies 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.
