Engine with ACERT™ Technology
Innovative technologies optimize performance.
The Cat C15 ACERT engine introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability.
Advanced Diesel Engine Management (ADEM) A4 Engine Controller
The ADEM A4 electronic control module manages fuel delivery and provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs.
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.
The Caterpillar seven-speed electronically controlled transmission features anti-hunt shift strategy for speed continuity, and Individual Clutch Modulation (ICM) to ensure constant shift times.
Controlled Throttle Shifting (CTS)
Significantly reduces power train stress and clutch wear by controlling engine speed, torque converter lock-up and transmission clutch engagements.
Two Reverse Gears
The transmission arrangement provides a second reverse gear for improved performance when operating in longer rear hauling applications.
Suspension and Traction Control
Performance and Productivity.
The three-point front suspension oscillate ±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.
Enclosed, Oil-Cooled Brakes
Multi-plate, oil-immersed, oil-cooled brakes are fitted to both front and center axles. These brakes provide outstanding stopping capability, while maintaining maximum durability and low wear characteristics.
Features a walking beam geometry with Caterpillar designed rear suspension mounts which provide a reliable and stable ride for excellent load retention.
The traction control system is comprised of a wet clutched inter-axle differential and wet clutched cross-axle differentials. All differentials can be engaged and disengaged "on-the-go" for maximum versatility. When used together, the differentials provide 100 percent driveline locking.
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.
High productivity for a comfortable, confident operator.
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 Ejector 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.
Full-size trainer seat features a fully padded seat with a backrest and a wide seatbelt for a secure and comfortable ride. The trainer seat is positioned next to the operator seat, giving both the operator and trainer a clear view of the instrument panel, controls and the road.
A comfortable driving position is provided by a telescopic and tilt steering column.
Ease of Operation
Designed for ease of use - allows the operator to focus on production.
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 allow the operator to concentrate on production.
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.
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.
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 "on-the go" 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 Ejector Levers
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.
Blade Retraction Sequence
The ejector blade returns to the loading position as soon as the blade retract sequence is initiated. The transmission is held in the gear selected for the ejecting cycle until this sequence is completed and the ejector control lever is returned to the float position.
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.
Durability and Reliability
High machine availability maximizes productivity and lowers costs.
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 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.
Oil-cooled, multiple disc brakes are continuously cooled for exceptional non-fading braking. They are designed and built for reliable, adjustment-free operation.
Located on the center axle in an elevated position and designed to deliver higher heat capacity and abuse resistance.
Disperse loads on-the-go for faster cycles and lower spreading costs.
The ejector body offers clean load ejection on-the-go and the capability to work in areas with restricted overhead clearance and soft underfoot conditions.
The 740 Ejector shares the versatility of the Standard 740 Articulated Truck, operating in the same conditions, but offering unique capabilities that stretch the operation envelope.
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.
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.
