Transmission – Class Leading Transmission Technology

Automatic Features – Ease of Use, Improved Performance

Automatic Features – Ease of Use, Improved Performance

Advanced Automatic Traction Control (AATC)
Advanced Automatic Traction Control (AATC) - 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. Clutches are automatically disengaged when ground conditions allow, maximizing efficiency when steering or when on uneven ground. AATC reduces tire and driveline abuse, eliminating machine inefficiencies caused by improper manual operation of the differential clutches and reducing the cost of premature tire replacement.
Automatic Retarder Control (ARC) - Fully automatic retarder control removes the need for any operator interaction. As with AATC, a number of machine operating aspects are monitored. The system can help towards eliminating engine overspeed yet gives the flexibility of manual speed adjustment, if necessary.
Assisted Dumping System - Tipping of the dump body can be done automatically with the new Assisted Hoisting Control. Full manual control is also possible.
Hill Assist - Hill Assist reduces potential ‘roll-back’ on grades. If an operator stops the machine on a grade, when taking the operator’s foot off the service brake pedal, the machine will automatically hold the service brakes to prevent machine from rolling backwards.
Waiting Brake - 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.

Ease of Operation – Designed for Operators, by Operators

Ease of Operation – Designed for Operators, by Operators

Control Layout
Control Layout - The new cab is designed to make all aspects of machine operation as simple as possible for every operator. The controls and gauges are easy to read and straightforward to use, allowing the operator to focus on safe machine operation while maintaining productivity.
Combined Hoist/Transmission Lever - Unique to Cat articulated trucks, the combined hoist/transmission lever provides easy, intuitive control of gears and hoist functions.
The new assisted hoist system gives improved control to the operator, allowing for faster cycle times and less control movements.
Offering both automatic and manual options, the system gives operators flexibility to choose their preferred method of control. When using the automatic system to tip a load, when flicking the switch to the ‘raise’ position, the machine neutralizes the transmission, applies the service brakes and hoists the body to maximum angle at the required engine rpm. When flicking the switch to the ‘lower’ position, the machine will automatically lower the body and place it in float. Both raise and lower functions feature automatic speed reduction and cushioning of the body at the limits of its movement, reducing forces that could otherwise cause shock loads.
Automatic use can reduce operator interactions by up to 50 percent, compared to the previous model, depending on the site tipping procedure. Also incorporated into the lever are waiting brake, transmission hold, machine speed limiter and parking brake selection. This gives operating a more automotive feel. No separate park brake switch is now needed; you just push the lever into park.
Dashboard - The newly styled and updated dash puts all controls within easy reach of the operator. It features LED illuminated rocker switches for easy use in all operating conditions. The fit and finish delivers an automotive feel with the industrial strength you would expect from Caterpillar.
Touchscreen Display - The updated touchscreen dash mounted display allows the operator to monitor and adjust various levels of machine performance and conditions, as well as machine warning categories. These include configuration settings, operator and machine totals, service information, various machine status parameters, machine payload information (when fitted), stability assist, and the video feed from the camera.
Bluetooth® Stereo Connectivity - Make and receive hands free calls via the optional Bluetooth equipped stereo with clearer quality due to the quieter cab and upgraded speakers.

Operator Environment – Improved Productivity with a Comfortable and Confident Operator

Operator Environment – Improved Productivity with a Comfortable and Confident Operator

Spacious Two-Person Cab
Spacious Two-Person Cab - The large open cab offers a comfortable working space for both the operator and an additional person (e.g. training purposes). The second seat is fully padded with a backrest and a wide, retractable seat belt for a secure and comfortable ride. Positioned adjacent to the operator, the forward facing seat gives the trainer a clear view of the instrument panel, controls and the road ahead.
Increased and Improved Storage - A new large side storage box is heated or cooled by the heating, ventilation, and air conditioning (HVAC) system depending on operator preference. New additional storage is now also available under the second seat. Twin cup holders and multiple storage spaces have also been introduced to help give operators an uncluttered workspace.
Air Suspension Seat - The new air suspension seat gives an increased range of adjustments over previous offerings including fore/aft isolation, which dramatically reduces horizontal vibrations and jolts. This provides a greater number of operators with the ability to tailor their seating position for a more comfortable working day.
Cab Atmosphere - The automatic climate control system gives you the option to maintain the temperature desired by the operator. In-cab noise of 72 dB contributes to a more comfortable working environment for the operator, all day, every day.

Suspension and Braking – Performance with Comfort

Suspension and Braking – Performance with Comfort

All three axles have oscillating A-frames with lateral tie rods, controlling sideways movement of the axle and providing stability. The suspension system allows the operator to travel at speed over rough terrain and softens impact loads on structures and components.
Suspension and Braking – Performance with Comfort
Front Suspension - 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.
Rear Suspension - Comprised of a walking beam and Caterpillar designed long life, maintenance free rear suspension mounts; the rear suspension system provides a reliable and stable ride for excellent travel over rough terrain and aids load retention.
All Axle Enclosed Wet Brakes - 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.
A-Frame Construction - The front suspension uses an oscillating A-frame with a lateral tie rod to control axle sideways movement and stability.

Durability and Reliability – Proven Structures and Components

Durability and Reliability – Proven Structures and Components

Front Frame
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.
Rear Frame - Twin-box construction minimizes stress concentrations and provides low weight with long service life.
Suspension - 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.
Articulating/Oscillating Hitch - The articulating hitch provides the truck with steering articulation, and the oscillation maximizes all-wheel ground contact in rough terrain.
Hitch Construction - Field proven two-piece construction features a durable cast steel head bolted to a hard wearing forged steel tube.
Dump Body Design - 740 GC has 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.
Output Transfer Gear (OTG) - Distributes drive to the tractor and trailer and includes a wet clutch inter-axle differential lock for optimum traction in poor underfoot conditions.
Service Brakes - Dual-circuit, all wheel braking system. The full power hydraulic system actuates enclosed, oil immersed, multi-disc, force cooled brakes with independent front and rear circuits and accumulators.
Parking Brake - Located on the center axle in an elevated position, it is spring applied and hydraulically released.

Automatic Features – Ease of Use, Improved Performance

Automatic Features – Ease of Use, Improved Performance

Advanced Automatic Traction Control (AATC)
Advanced Automatic Traction Control (AATC) - 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. Clutches are automatically disengaged when ground conditions allow, maximizing efficiency when steering or when on uneven ground. AATC reduces tire and driveline abuse, eliminating machine inefficiencies caused by improper manual operation of the differential clutches and reducing the cost of premature tire replacement.
Automatic Retarder Control (ARC) - Fully automatic retarder control removes the need for any operator interaction. As with AATC, a number of machine operating aspects are monitored. The system can help towards eliminating engine overspeed yet gives the flexibility of manual speed adjustment, if necessary.
Assisted Dumping System - Tipping of the dump body can be done automatically with the new Assisted Hoisting Control. Full manual control is also possible.
Hill Assist - Hill Assist reduces potential ‘roll-back’ on grades. If an operator stops the machine on a grade, when taking the operator’s foot off the service brake pedal, the machine will automatically hold the service brakes to prevent machine from rolling backwards.
Waiting Brake - 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.

Ease of Operation – Designed for Operators, by Operators

Ease of Operation – Designed for Operators, by Operators

Control Layout
Control Layout - The new cab is designed to make all aspects of machine operation as simple as possible for every operator. The controls and gauges are easy to read and straightforward to use, allowing the operator to focus on safe machine operation while maintaining productivity.
Combined Hoist/Transmission Lever - Unique to Cat articulated trucks, the combined hoist/transmission lever provides easy, intuitive control of gears and hoist functions.
The new assisted hoist system gives improved control to the operator, allowing for faster cycle times and less control movements.
Offering both automatic and manual options, the system gives operators flexibility to choose their preferred method of control. When using the automatic system to tip a load, when flicking the switch to the ‘raise’ position, the machine neutralizes the transmission, applies the service brakes and hoists the body to maximum angle at the required engine rpm. When flicking the switch to the ‘lower’ position, the machine will automatically lower the body and place it in float. Both raise and lower functions feature automatic speed reduction and cushioning of the body at the limits of its movement, reducing forces that could otherwise cause shock loads.
Automatic use can reduce operator interactions by up to 50 percent, compared to the previous model, depending on the site tipping procedure. Also incorporated into the lever are waiting brake, transmission hold, machine speed limiter and parking brake selection. This gives operating a more automotive feel. No separate park brake switch is now needed; you just push the lever into park.
Dashboard - The newly styled and updated dash puts all controls within easy reach of the operator. It features LED illuminated rocker switches for easy use in all operating conditions. The fit and finish delivers an automotive feel with the industrial strength you would expect from Caterpillar.
Touchscreen Display - The updated touchscreen dash mounted display allows the operator to monitor and adjust various levels of machine performance and conditions, as well as machine warning categories. These include configuration settings, operator and machine totals, service information, various machine status parameters, machine payload information (when fitted), stability assist, and the video feed from the camera.
Bluetooth® Stereo Connectivity - Make and receive hands free calls via the optional Bluetooth equipped stereo with clearer quality due to the quieter cab and upgraded speakers.

Operator Environment – Improved Productivity with a Comfortable and Confident Operator

Operator Environment – Improved Productivity with a Comfortable and Confident Operator

Spacious Two-Person Cab
Spacious Two-Person Cab - The large open cab offers a comfortable working space for both the operator and an additional person (e.g. training purposes). The second seat is fully padded with a backrest and a wide, retractable seat belt for a secure and comfortable ride. Positioned adjacent to the operator, the forward facing seat gives the trainer a clear view of the instrument panel, controls and the road ahead.
Increased and Improved Storage - A new large side storage box is heated or cooled by the heating, ventilation, and air conditioning (HVAC) system depending on operator preference. New additional storage is now also available under the second seat. Twin cup holders and multiple storage spaces have also been introduced to help give operators an uncluttered workspace.
Air Suspension Seat - The new air suspension seat gives an increased range of adjustments over previous offerings including fore/aft isolation, which dramatically reduces horizontal vibrations and jolts. This provides a greater number of operators with the ability to tailor their seating position for a more comfortable working day.
Cab Atmosphere - The automatic climate control system gives you the option to maintain the temperature desired by the operator. In-cab noise of 72 dB contributes to a more comfortable working environment for the operator, all day, every day.

Suspension and Braking – Performance with Comfort

Suspension and Braking – Performance with Comfort

All three axles have oscillating A-frames with lateral tie rods, controlling sideways movement of the axle and providing stability. The suspension system allows the operator to travel at speed over rough terrain and softens impact loads on structures and components.
Suspension and Braking – Performance with Comfort
Front Suspension - 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.
Rear Suspension - Comprised of a walking beam and Caterpillar designed long life, maintenance free rear suspension mounts; the rear suspension system provides a reliable and stable ride for excellent travel over rough terrain and aids load retention.
All Axle Enclosed Wet Brakes - 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.
A-Frame Construction - The front suspension uses an oscillating A-frame with a lateral tie rod to control axle sideways movement and stability.

Durability and Reliability – Proven Structures and Components

Durability and Reliability – Proven Structures and Components

Front Frame
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.
Rear Frame - Twin-box construction minimizes stress concentrations and provides low weight with long service life.
Suspension - 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.
Articulating/Oscillating Hitch - The articulating hitch provides the truck with steering articulation, and the oscillation maximizes all-wheel ground contact in rough terrain.
Hitch Construction - Field proven two-piece construction features a durable cast steel head bolted to a hard wearing forged steel tube.
Dump Body Design - 740 GC has 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.
Output Transfer Gear (OTG) - Distributes drive to the tractor and trailer and includes a wet clutch inter-axle differential lock for optimum traction in poor underfoot conditions.
Service Brakes - Dual-circuit, all wheel braking system. The full power hydraulic system actuates enclosed, oil immersed, multi-disc, force cooled brakes with independent front and rear circuits and accumulators.
Parking Brake - Located on the center axle in an elevated position, it is spring applied and hydraulically released.
