Engine with ACERT™ Technology
Innovative technologies optimize performance.
ACERT TechnologyThe Cat® C11 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 ControllerThe ADEM™ A4 electronic control module manages fuel delivery and provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs.
Fuel DeliveryMultiple 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 TechnologiesNoise 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.
Electronic TransmissionThe Caterpillar six-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.
Engine Overspeed InhibitorElectronic Transmission Control (ETC) protects against engine overspeeding.
Suspension and Traction Control
Performance and Productivity.
Front SuspensionThe 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.
A-Frame ConstructionThe front suspension uses an oscillating A-frame with a lateral tie rod to control axle sideways movement.
Rear SuspensionFeatures a walking beam geometry with Caterpillar designed rear suspension mounts which provide a reliable and stable ride for excellent load retention.
Traction ControlThe 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 LockLocks 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 LocksProvides 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.
Mounting PointsSuspension mounting points are integrated into the axle housing, increasing reliability.
High productivity from a comfortable, confident operator.
Ride ComfortThe 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 CabThe 730 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 SeatThe 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 SeatFull-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.
Steering ColumnA comfortable driving position is provided by a telescopic and tilt adjustable steering column.
Ease of Operation
Designed for ease of use – allows the operator to focus on production.
Ergonomic LayoutThe 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 730 Ejector allow the operator to concentrate on production.
DashThe 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 AreaThe 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.
WipersThe 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 ControlsThe inter-axle differential lock can be 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 Eject LeversThe eject lever provides easy, comfortable operation. The transmission lever offers excellent comfort, and control for top gear limit, transmission hold and neutral lock.
Suspended PedalsEasy 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.
Front FrameThe 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 FrameTwin-box construction minimizes stress concentrations and provides low weight with long service life.
SuspensionThe 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 HitchThe articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain.
Hitch ConstructionTwo-piece construction features a durable cast steel head bolted to a hard-wearing forged steel tube.
Service BrakesDual-circuit, all wheel braking system. Full power hydraulic system actuates self cleaning caliper disc brakes with independent front and rear circuits and accumulators.
Parking BrakeLocated on the center axle in an elevated position out of the dirt and designed to deliver higher heat capacity and abuse resistance.
Disperse loads on-the-go for faster cycles and lower spreading costs.
EjectorThe ejector body offers clean load ejection and the capability to work in areas with restricted overhead clearance and soft underfoot conditions.
VersatilityThe 730 Ejector shares the versatility of the Standard 730 Articulated Truck, operating in the same conditions, but offering unique capabilities that stretch the operation envelope.
SpreadingThe 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.
StabilityEjecting 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 ClearanceThe truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations.
Carry-BackThe body design eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.
BodyReinforced body is made from thick high-yield, heat-treated Brinell hardened steel (Brinell 450 on the base and Brinell 400 on the 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.
BladeThe ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.
CylinderA three-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and smooth load ejection.
