The Cat® C15 ACERT™ engine continues the evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability.
Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.
The ADEM A4 electronic control module manages fuel delivery to get the best performance per liter or gallon of fuel used. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak efficiency.
Single wastegate turbocharging provides higher boost over a wide range, outstanding low end performance with improved peak torque and engine response.
A highly evolved fuel system with a proven record of reliability in the field. It combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. It excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C15 to have complete control over injection timing, duration and pressure.
ATAAC keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in air flow are generated by a turbocharger, unique cross-flow head and a single overhead camshaft.
The Cat® seven-speed forward, two speed reverse Electronic Clutch Pressure Controlled (ECPC) transmission features enhanced shift control logic with anti-hunt shift strategy for speed continuity, and to ensure constant shift times.
ECPC control is matched to the min-max governor control for precise smooth shifting.
The transmission arrangement provides a second reverse gear for improved performance when operating in longer rear hauling applications.
The 740B EJ features ECPC Shift Torque Management (STM), with improved Shift Control Logic (SCL) and Part Throttle Shifting (PTS). These features allow smoother shifting and greater acceleration on grades while torque is maintained through the shift changes. SCL also provides automatic shift selection that is more specific to the desired machine operation, and downshifts when needed for maximum acceleration when increased throttle is applied. PTS allows shifting at lower speeds during part throttle operation, resulting in improved part throttle fuel economy, quieter machine operation, and better maneuvering in reduced speed operating conditions.
The three-point front suspension oscillates ±6° to provide a smooth ride, allowing the operator to travel at speed over rough terrain and softening impact loads on structures and components. Large bore, low pressure cylinders are purpose designed for tough applications and offer a soft, smooth ride.
Features a walking beam geometry with Caterpillar designed rear suspension mounts which provide a reliable and stable ride for excellent load retention.
Fully Automatic Traction Control (ATC). Inter-Axle-Differential lock (IAD) and Cross-Axle-Differential lock (XAD) feature oil immersed clutches that require no operator input. Operation is seamless and smooth, and it eliminates wheel slip for maximum traction. Sensors monitor the machine and wheel speeds, enabling instant response in low traction conditions. Fully automatic, independent IAD and XAD clutches are engaged on-the-go to optimize machine performance and control in all conditions. Clutches are automatically disengaged when ground conditions dictate, maximizing efficiency when steering or on uneven ground. ATC eliminates wheel spin in soft under foot extreme ground conditions where little traction is available. It also reduces tire and driveline abuse eliminating lost efficiency caused by improper manual operation of the differential clutches.
The Cat engine compression brake control lever is positioned on the right-hand side of the steer column. Four modes of operation with three steps of retardation, provide an optimum match between operating conditions and retarding power.
The three-point front suspension with its oscillating axle and low-pressure ride struts, combined with the center-mounted cab, offers unrivaled levels of ride comfort for the operator in all driving conditions. The operator remains comfortable and productive throughout the day.
The 740B EJ features a large two-person cab, offering comfortable working space for both the operator and trainer or trainee. The 735B, 740B and 740B EJ articulated trucks use the same spacious cab design.
The air suspension seat enhances operator comfort with a cushioned upper high back, adjustable damping with three settings, ride zone indicator and adjustable lumbar settings. It is fully adjustable to provide the optimal driving position.
Full-size passenger seat features a fully padded seat with a backrest and a wide, retractable seat belt for a secure and comfortable ride. The passenger seat is positioned next to the operator seat, giving both the operator and passenger a clear view of the instrument panel, controls and the road.
A comfortable driving position is provided by a telescopic and tilt adjustable steering column.
The controls and layout of the cab are designed to make it as easy to operate as your car. Quick, easy to read and simple to operate, the controls and gauges on the 740B EJ allow the operator to concentrate on production.

It provides an automotive feel with the industrial strength you would expect from Caterpillar.
A multi screen display unit showing various levels of machine warning categories, performance and condition pages, including: Performance, Settings, Totals, Service, Machine Status, Operator, and Rearview Camera.
The monitoring system provides four warning categories. The first warning category requires only operator awareness. The second warning category requires a change to machine operation or performance of maintenance to the system. The third warning category requires an immediate change of the machine operation. The fourth category requires the operator to immediately stop the machine. The fourth category also requires the operator to immediately shut down the engine.
The low sloping hood and placement of the cooling package behind the cab give the operator excellent all-around visibility. The large glass area and central operator position also provide excellent visibility.
Finger tip controls allow easy operation and low effort. The ejector and transmission levers are positioned for easy comfortable operation, along with the control for top gear limit, transmission hold and neutral lock.
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.
Twin-box construction minimizes stress concentrations and provides low weight with long service life.
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.
The articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain.
Two-piece construction features a durable cast steel head bolted to a hard-wearing forged steel tube.
Fast body raise and lower times mean less time spent in the dump area.
The 740B EJ has a large target area to provide consistently high load-carrying capacity. Its diverging flow design gives clean load ejection, which maximizes production and avoids the waste of material carry-back.
