Engine with ACERT™ Technology

Innovative technologies optimize performance.

ACERT Technology

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.

Cat Clean Emissions Module (CEM)

CEM is an exhaust aftertreatment package consisting of a diesel particulate filter, and control systems. The CEM reduces particulate emissions using passive and active regeneration during normal engine operation.

Cat NOx Reduction System (NRS)

The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

Fuel Delivery

Mechanically actuated Electronic Unit Injection (MEUI-C) 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.

Diesel Particulate Filter Regeneration


Proven Reliability.

Electronic Transmission

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.

Min-max Governor Control

ECPC control is matched to the min-max governor control for precise smooth shifting.

Two Reverse Gears

The transmission arrangement provides a second reverse gear for improved performance when operating in longer rear hauling applications.

Smooth Transmission Gear Shifting

The 740B 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.

Suspension and Automatic Traction Control (ATC)

Performance and Productivity.

Front Suspension

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.

Rear Suspension

Features a walking beam geometry with Caterpillar designed rear suspension mounts which provide a reliable and stable ride for excellent load retention.

Automatic Traction Control

Fully Automatic Traction Control (ATC). Inter-Axle-Differential lock (IAD) and Cross-Axle-Differential locks (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.

Retardation Control

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.

Operator Comfort

High productivity from a comfortable, confident operator.

Color Multi-Purpose Display (CMPD) unit incorporating the messenger and rearview display. Provides an automotive feel with the industrial strength you would expect from Caterpillar.

Color Multi Purpose Display (CMPD)

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.

Warning Categories

The monitoring system provides four warning categories. The first warning category requires only operator awareness. The second warning category requires a change in machine operation or 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.

Viewing Area

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.

Transmission and Hoist Levers

The hoist lever provides easy, comfortable operation. The transmission lever offers excellent comfort, and control for top gear limit, transmission hold and neutral lock.

Durability and Reliability

High machine availability maximizes productivity and lowers costs.

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.


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 ensures all-wheel ground contact in rough terrain.

Hitch Construction

Two-piece construction features a durable cast steel head bolted to a hard-wearing forged steel tube.
