2022 Caterpillar Three Axle AT 740 GC

2022 Caterpillar Three Axle AT 740 GC

The Cat® 740 GC 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.

• Advanced Automatic Traction Control (AATC) proactively applies inter- and cross-axle differential locks ‘on-the-go.’ Operators are freed from this function to concentrate on driving/loading/dumping. 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 productivity.

• Clutches are automatically disengaged when ground conditions allow, maximizing efficiency when steering or when on uneven ground.

• AATC reduces tire and driveline abuse, eliminating lost machine efficiencies caused by improper manual operation of the differential clutches and reducing the tire wear.

• Automatic Retarder Control (ARC) automates the retarder for the operator. Like AATC, a number of machine operating aspects are monitored. If required, the engine compression brake is engaged automatically to control machine speed when descending a grade. The system can help towards eliminating engine overspeed, improving safe machine operation and reducing cycle times, yet still having the flexibility of manual control if needed.

• New Assisted Hoisting Control automates the dumping function. Flick the new body raise/lower switch and the machine will apply the service brakes, switch the transmission to neutral and raise the body at the required engine rpm. Lowering the dump body is done the same way, flick the switch and the machine will lower the body and place it in float.

• Hill Assist reduces potential ‘roll-back’ on grades. If an operator stops the machine on a grade, when taking his foot off the service brake pedal, the machine will automatically hold the service brakes to prevent machine rolling backwards.

• The Waiting brake applies the service brakes when neutral gear is selected, allowing quick and easy control of the machine at the load or dump area.
