Benefits & Features

Ease of Operation

Designed for operators, by operators

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 Eject/Transmission Lever

Unique to Cat Articulated Trucks, the combined eject/transmission lever provides easy, intuitive control of gears and eject functions. The new assisted eject 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 eject a load statically, the machine neutralizes the transmission, applies the service brakes and ejects the blade at the required engine rpm. On-the-go ejection can be controlled by the operator to spread material as required. Automatic use can reduce operator interactions by up to 50 percent depending on the site ejecting procedure.

Waiting brake, transmission hold and machine speed limiter functions are easily accessed using the buttons on the lever. The park brake has also been incorporated giving operation a more automotive feel. No separate switch is now needed; you just push the lever into park.


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.

Touch Screen Display

The updated touch screen dash mounted display allows the operator to monitor and adjust various levels of machine performance and condition, 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 rearview 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

Spacious Two-Person Cab

The large open cab with increased headroom, 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 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 HVAC system depending on operator preference. 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. The seat can be selected with variable climate control as an option.

Cab Atmosphere

The improved climate control system gives you the option to maintain the temperature desired by the operator. The addition of Infra Red Reflective (IRR) glass and integrated window blinds helps guard against the effects of bright sunlight.

A reduction to in-cab noise (–7 dB from previous model) contributes to a more comfortable working environment for the operator, all day, every day.


Optimized performance, proven reliability

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:

  • All new Eco mode, which can provide an average reduction in fuel consumption of 5 percent over normal operation.
  • High machine performance across all 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 operate 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

Cat Tier 4 Final/Stage IV 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, meeting the additional 80 percent reduction in NOx emissions required by Tier 4 Final/Stage IV emission standards.

Diesel Exhaust Fluid (DEF)

Cat engines equipped with a Selective Catalytic Reduction (SCR) system inject 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.

Engine Compression Brake

The engine compression brake improves retarding response and increases retarding power for controlled descent of grades.


Class leading transmission technology

The Cat High Density Power Shift (HDPS) nine-speed forward two-speed reverse transmission, designed specifically for Articulated Trucks, features Advanced Productivity Electronic Control Strategy (APECS) and Electronic Clutch Pressure Control (ECPC) that 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 are configured to maintain direct drive lock-up, and reduce dropping into converter drive. Decreasing the use of torque converter drive aids in maintaining ground speed and gradeability.

Variable gearshift points are used based on the operating conditions, which also aid in maintaining ground speed during gear changes on grades.

Torque Converter

Large diameter torque converter, configured for off highway applications, allows the higher engine power to be transmitted more efficiently to the lower power train.

Automatic Features

Ease of use, improved performance

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 lost machine efficiencies caused by improper manual operation of the differential clutches, and reducing the cost of premature tire replacement.

Automatic Retarder Control (ARC)

In automatic mode, use of the retarder is much easier for the operator. As with AATC a number of machine operating aspects are monitored, and if required the engine compression brake is engaged automatically. The system can help towards eliminating engine overspeed, improving safe machine operation and reducing cycle times, yet still with the flexibility of manual control if needed.

Assisted Ejecting System

Ejecting material from the dump body can be done automatically with the new Assisted Ejecting Control. Flick the new load eject switch and the machine will apply the service brakes, switch the transmission to neutral and push the material out at the required engine RPM. Retracting the blade is done the same way, flick the switch and the machine will fully retract the blade. Two flicks, one out, one in.

Suspension and Braking

Performance with comfort

Front Suspension

The three-point front suspension design provides the mechanism required to travel at speed over rough terrain and softens impact loads on structures and components. Large bore, low-pressure cylinders are purposely designed for Articulated Truck applications and offer a soft, smooth ride for the operator.

A-Frame Construction

The front suspension uses an oscillating A-frame with a lateral tie rod to control axle sideways movement and stability.

Rear Suspension

The rear suspension features a walking beam with Caterpillar designed rear suspension mounts, which have long life and provide a reliable, and stable ride for excellent load retention.

Axle Enclosed Wet Brakes

All axle enclosed wet brakes provide high retarding and braking performance with improved holding on grades.

Hill Assist

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 on for a number of seconds to prevent the 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.


Pushing the operating envelope

The 740 EJ shares the versatility of the 745, operating in the same conditions, but offering unique capabilities that stretch the operation envelope.

The introduction of the new combined eject/transmission lever gives you the option to auto eject, as well as full manual control.


The truck can eject and spread the material while moving, reducing additional spreading and dozing equipment. “On-the-go” ejecting results in faster cycle times and reduced power train loads.


Ejecting the load without raising the body increases stability, allowing load dispersal on inclines, side slopes and in very soft underfoot conditions especially on landfill sites.

Overhead Clearance

The truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations.


The body design eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.


Reinforced body is made from thick high-yield, heat-treated Brinell hardened steel (Brinell 400 on the base and sides) that provides exceptional durability. Ejector top rails are made from high-strength alloy steel. For optimum durability and wear life, the ejector body is designed to work in applications where the material consists of rocks smaller than 152 mm (6 in) in diameter.


The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.


A four-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and smooth load ejection.

Durability and Reliability

Proven structures and components

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.

Articulating/Oscillating Hitch

The articulating hitch provides the truck with steering articulation, and the oscillation ensures 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

The 740 EJ has a large target area to provide consistently high load-carrying capacity. Eject blade and body design aids in clean material discharge, maximizing production and avoiding carry-back.

Output Transfer Gear (OTG)

The output transfer gear distributes drive to the tractor and trailer and includes a wet clutch differential lock for optimum traction in poor underfoot conditions.

Service Brakes

The full power hydraulic system actuates enclosed, oil immersed, multi disc, multi plate brakes with independent front and rear circuits and accumulators. This dual-circuit, all wheel braking system provides the braking performance required to support maximum productivity.

Parking Brake

The parking brake is located on the center axle in an elevated position, it is spring applied and hydraulically released.

Operators can track daily productivity from the cab, with quick access to truck payload weights, loads and cycle counts, and daily totals; or remotely via LINK technologies.

Cat Detect with Stability Assist

Cat Detect with Stability Assist warns the operator if machine is approaching an unsafe angle during operation; when driving and ejecting. If using the assisted hoist, the machine will stop ejecting the blade and give an audible and visual warning. The system monitors angles of tractor, trailer and grade independently. This increases operator awareness of machine stability during operation. All tractor and/or trailer rollover events are logged and reported via VisionLink.


Maximize uptime and reduce costs

Long Service Intervals

Changes to oil change intervals, volumes and the type of oil required will help lower maintenance costs and machine downtime.

Lubrication Points

Lubrication points are grouped in the hitch area for ease of servicing. Universal joints are lubed for life, eliminating any maintenance. An Autolube system is also optional, and now includes alerts via Product Link for low grease levels.
