Engine with ACERT„¢ Technology

The core concept behind ACERT„¢ technology is advanced combustion. ACERT engine technology carefully controls the combustion process to reduce pollutant levels while maintaining performance and efficiency.

ACERT Technology

Advanced Diesel Engine Management (ADEM) A4 Engine Controller

Fuel Delivery

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.

Noise Reduction Technologies

Noise reduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing case cover, sculpted crankcase and gear train refinements.

Transmission

The Cat® C15 ACERT engine, matched with the seven-speed forward and two-speed reverse electronic controlled transmission, provides a wide operating range for smooth shifting.

Electronic Transmission

Controlled Throttle Shifting (CTS)

Transmission clutch life is a function of the number of shifts and the level of stress during each shift. CTS significantly reduces power train stress and clutch wear by controlling engine speed, torque converter lock-up and transmission clutch engagements. CTS helps extend transmission life.

Engine Overspeed Inhibitor

Electronic Transmission Control (ETC) protects against engine overspeeding by shifting the transmission up one gear at specified rpm settings. If the transmission is in its highest gear, torque converter lockup disengages.

Directional Shift Management

Regulates engine speed during directional shifts to prevent damage caused by high-speed directional changes.

Programmable Top Gear Selection

Electronic Transmission Control lets you electronically limit top gear selection without the use of additional service tooling or mechanical limiting of the shift cane.

Two Reverse Gears

Suspension and Traction Control

Three-point front suspension provides a smooth ride, allowing the operator to travel at speed over rough terrain. Cross-axle differential locking system provides full driveline locking for maximum performance in adverse conditions.

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.

A-Frame Construction

The front suspension uses an oscillating A-frame with a lateral tie rod to control axle sideways movement. The independent low-pressure, oil-nitrogen suspension cylinders provide an excellent ride in rough conditions. Low pressure ensures consistent damping and increased seal life.

Mounting Points

Suspension mounting points are integrated into the axle housing, increasing reliability.

Enclosed, Oil-Cooled Brakes

Multi-plate, oil-immersed brakes are fitted to both front and center axles. These brakes provide outstanding stopping capability, while maintaining maximum durability and low wear characteristics.

Rear Suspension

The rear suspension features a walking beam geometry that extends component life and provides a stable ride for excellent load retention. The walking beams are connected to the axles by the Caterpillar elastomer suspension mounting, specifically designed for the articulated truck.

Traction Control

The 740s traction control system is comprised of a wet clutched inter-axle differential and wet clutched cross-axle differentials. To increase reliability, the 740 uses larger and fewer clutches. All differentials offer true on-the-go engagement and disengagement to keep the truck moving in all conditions and to avoid costly wheelspin. When used together, the differentials provide 100 percent lockup of all six wheels.

Inter-Axle Differential Lock

Locks all three axles in unison and modifies torque distribution for excellent traction in poor underfoot conditions and on grades. It is operated by a switch located at the footrest.

Cross-Axle Differential Locks

Provides full driveline locking “ all three axles and all six wheels “ for maximum performance in the most adverse conditions. Acts in unison with the inter-axle differential lock when the footswitch is actuated and the dash-mounted switch is selected.

Operator Comfort

Large center-mounted cab, oscillating front axle, air suspension seat, full-size trainer seat and large storage space provide exceptional operator comfort.

Ride Comfort

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.

Spacious Two-Person Cab

The 740 features a large two-person cab, offering comfortable working space for both the operator and trainer or trainee. All 700 Family articulated trucks use the same spacious cab design.

Air Suspension Seat

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.

Trainer Seat

Steering Column

Telescopic and tilt features provide a comfortable driving position. Column has two ergonomically designed control levers: engine compression brake control on the right and intermittent wiper-washer, turn signal, dimmer control and flash-to-pass function on the left.

Ease of Operation

Ergonomically designed wrap-around dash, tilt and telescopic steering wheel, easy-to-reach controls and outstanding all-around viewing promote fast, confident machine operation.

Ergonomic Layout

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 740 allow the operator to concentrate on production.

Dash

The Generation II wrap-around dash puts all controls within easy reach of the operator. Featuring LED illuminated rocker switches, large LCD display and a rear wash wipe rocker switch. It provides an automotive feel with the industrial strength you would expect from Caterpillar.

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 enhance visibility, resulting in more operator confidence and fast cycle times. The design of the door panel, body panels, dash, hood and rear window guard provide excellent visibility to the ground.

Wipers

The wet arm wiper system cleans more glass area and is bottom-mounted to keep it out of the operator's line of sight. Windows are tinted to reduce glare.

Differential Lock Controls

The inter-axle differential lock is engaged/disengaged by using a raised switch incorporated into the drivers foot rest, for ease of operation. For 100% lock up, all three cross-axle differential locks act in unison with the inter-axle differential lock when the foot switch is activated and a dash mounted switch is selected. Disengaging the foot switch opens all differential locks immediately.

Transmission and Hoist Levers

The hoist lever is positioned for easy, comfortable operation. The transmission lever offers excellent comfort, along with the control for top gear limit, transmission hold and neutral lock.

Suspended Pedals

Easy to operate and reach with plenty of leg and foot room. They also make for easier cleaning of the cab floor by keeping the pedals out of the dirt.

Cat 2S Monitoring System

Provides an improved method of monitoring critical machine functions and alerts the operator to an immediate or impending problem. The system includes four levels of warning:

Durability and Reliability

The 740 has built-in durability and reliability. Cat purpose-built articulated truck drivetrain components, front frame and hitch ensure maximum performance in the toughest applications.

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 is also designed to make 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 the most adverse road conditions by absorbing many of the shock loads that would otherwise reach the frame.

Articulating/Oscillating Hitch

The articulating hitch provides the truck with steering articulation, and the oscillation ensures the truck maintains all-wheel ground contact in rough terrain.

Hitch Construction

Fast Hoist Cycle Times

The 740 body raises in 12 seconds and lowers in 7 seconds. It features a 71° hoist angle with power up and down for clean load ejection and fast dump cycles. Double-acting, single stage hoist cylinders and a powerful dedicated hydraulic system deliver class-leading performance.
