Optimized Performance, Proven Reliability
Engine TechnologyThe Cat C13 ACERT engine continues the evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability.
Fuel DeliveryMechanically 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.
Engine Compression BrakeThe Cat C13 ACERT engine compression brake improves retarding response and increases retarding power.
Retarder PowerIncreased power capability gives operators greater control on short, steep grades and minimizes the need to apply the service brakes, resulting in extended service brake life. It retains four modes of operation, with three stages of retardation, so operators can match the level of retarding to the grade resistance.
Class Leading Transmission Technology
The Cat CX31 six-speed forward one-speed reverse Electronic Clutch Pressure Controlled (ECPC) transmission featuring Advanced Productivity Electronic Control Strategy (APECS) delivers smooth shifting with strong acceleration and high productivity. The Cat C13 ACERT engine coupled with the CX31 transmission deliver increased forward and reverses rimpull. Featuring:
- A speed hold/limiting function allows the machine speed to be limited in one km/h or one mph steps to conform to site speed restrictions.
- Critical gearshifts maintain direct drive lock-up, and eliminate dropping into converter drive. This maintains ground speed during shifts on grades.
- The transmission automatically modifies shift points to best suit operating conditions.
- Retarding levels are automatically reduced on lesser grades in lower gears.
Torque ConverterA large diameter torque converter, configured for off highway applications, allows the engine power to be transmitted more efficiently to the lower power train.
Automatic Traction Control (ATC)
The Most Advanced Traction Control System
Automatic Traction Control (ATC)Fully Automatic Traction Control (ATC), with 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, eliminating 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. Clutches are engaged proportionally, from 0% to 100%, as ground conditions dictate. ATC eliminates wheel spin in soft underfoot ground conditions or on slippery grades. It also reduces tire and driveline abuse caused by improper manual operation of the differential clutches. The ATC allows ‘true’ 6×6 drive with proportionally open differentials for best power efficiency.
Suspension and Brakes
Performance and Comfort
Front SuspensionThe three-point front suspension oscillates ±6° to provide a smooth ride, allowing the operator to travel at speed over rough terrain. It softens impact loads on structures and components using an oscillating A-frame with a lateral tie rod to control axle sideways movement. Large bore, low-pressure cylinders are purpose designed for tough applications and offer a soft, smooth ride.
Rear SuspensionThe rear suspension features walking beam geometry with Caterpillar designed, long life, rear suspension mounts, which provide a reliable and stable ride for excellent load retention.
Mounting PointsSuspension mounting points are integrated into the axle housing, increasing reliability.
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 BrakeFitted to the center axle in an elevated position, spring applied and hydraulically released.
Improved Productivity from a Confident Operator
Ride ComfortThe three-point front suspension with its oscillating axle and low-pressure ride struts, combined with the center-mounted cab, offer 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 730C features a large two-person cab, offering comfortable working space for both the operator and passenger with large storage compartments. The 725C, 730C EJ, 735B, 740B and 740B EJ 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.
Passenger SeatFull-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.
Steering ColumnA comfortable driving position is provided by a telescopic and tilt adjustable steering column.
Ease of Operation
Designed around the Operator
Ergonomic LayoutThe controls and layout of the cab are designed to make operation as easy as your car. Quick, easy to read and simple to operate, the controls and gauges on the 730C allow the operator to concentrate on production.
DashThe integrated wrap-around dash puts all controls within easy reach of the operator. Featuring LED illuminated rocker switches for the dash dimmer, rear wash wiper, hazard warning, head lamp, work lamp, heated mirrors (optional), secondary steer, heated seat (optional), machine security system (optional), A/C and cigar lighter. The Color Multi-Purpose Display (CMPD) unit incorporates the messenger and rear camera display. The cab provides an automotive feel with the industrial strength you would expect from Caterpillar.
Color Multi-Purpose Display (CMPD)The cab features 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 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 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.
Transmission and Hoist LeversThe transmission lever offers excellent comfort and control for transmission selection, hold and neutral lock. The hoist lever provides easy, comfortable operation.
Proven Durability and Reliability
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 FrameThe four plate box constructed rear frame minimizes stress concentrations and provides low weight with long service life.
Dump BodyExtensive use of 450 Brinell hardened steel provides excellent impact and wear resistance. Body top rail design reduces material spillage at the loading area. Diverging flow construction gives clean load ejection which maximizes production and avoids the waste of material carry back.
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 ConstructionThe two-piece construction of the hitch features a durable cast steel head bolted to a hard wearing forged steel tube.
