2022 Caterpillar Three Axle AT 730

2022 Caterpillar Three Axle AT 730

The Cat® 730 features a world-class cab design, re-engineered using global operator feedback to advance comfort and ease of operation. Enhancements include new controls, transmission-protection features, hoist-assist system, advanced automatic traction control system, stability-assist machine rollover warning system, and a fuel saving ECO mode.

Features may include:

• Every Tier 4 Final/Stage IV and EU Stage V Cat engine is equipped with a combination of proven electronic, fuel, air and aftertreatment components.

• 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.

• 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.

• The Cat NOx Reduction System (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.

• 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 percent high purity chemical grade urea and 67.5 percent 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.

• The engine compression brake improves retarding response and increases retarding power.

• Advanced automatic traction control (AATC) is a proactive 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 diff lock. Sensors monitor the machine and wheel speeds, enabling instant response in high rolling resistance conditions. Operation is seamless and smooth, eliminating wheel slip for maximum traction and therefore productivity.
