Optimized Performance, Proven Reliability


Engine Technology
The Cat C9.3 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)
The Cat CEM is an exhaust aftertreatment package consisting of a Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) catalyst, using a Urea Water Solution (UWS), known as Diesel Exhaust Fluid (DEF), and control systems. The CEM reduces both particulate and NOx emission using passive and active regeneration, dosing, burner and dosing/burner combinations during normal engine operation. All components are isolation mounted on a rigid supporting cradle for long service life in the most severe applications.

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
The Cat C9.3 ACERT engine utilizes the common rail, high-pressure, electronic metering system to the injectors.

Diesel Particulate Filter Regeneration
Regeneration is the removal of soot from the Diesel Particulate Filter (DPF). The Aftertreatment Regeneration Device (ARD) utilizes the Cat Regeneration System (CRS) to efficiently and automatically regenerate the DPF. The DPF traps both particulates and ash; the ash is removed at regular service intervals.

Modes of Regeneration
When set to automatic, regeneration will occur without any interaction from the operator. The three modes of regeneration shown below allow the articulated truck to adapt to specific site conditions in the most efficient manner. Automatic: “On-the-go” regeneration is initiated when the engine control module determines conditions are acceptable. The articulated truck is not required to stop working. Automatic: Low Idle regeneration is initiated when the machine is in a reduced operating mode for a predetermined period of time, and a number of conditions are met. The system is designed so that the operator can interrupt regeneration at any time. Manual: A manual regeneration is initiated by pressing the regeneration switch for five seconds. The machine must be brought to a non-operating mode in order to perform a manual regeneration.

Class Leading Transmission Technology


Electronic Transmission
The Cat TH31 six-speed forward one-speed reverse Electronic Clutch Pressure Controlled (ECPC) transmission featuring Advanced Productivity Electronics Control Strategy (APECS) delivers smooth shifting with strong acceleration and high productivity. • Features: - 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.

Integral transmission retarder with a high power density design. Due to its compact size, the unit quickly fills with oil, providing more retarding power and fast response times. Retarding levels are automatically reduced on lesser grades in lower gears.

Traction Control
The Most Advanced Traction Control System

Traction Control

Traction Control
The traction control system is comprised of wet clutched inter-axle and cross-axle differentials, which can be engaged and disengaged “on-the-go.”

Inter-Axle Differential Lock
Locks tractor and trailer drive systems together and modifies torque distribution for excellent traction in poor underfoot conditions and on grades. Operated by a switch located at the footrest.

Cross-Axle Differential Locks
Locks axle differentials, acting in unison with the inter-axle differential lock when the foot switch is actuated and the dash-mounted switch is selected.

Suspension and Brakes
Performance and Comfort

Suspension and Brakes

Front Suspension
The 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 Suspension
The rear suspension features a walking beam geometry with Caterpillar designed, long life, rear suspension mounts, which provide a reliable and stable ride for excellent load retention.

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

Service Brakes
Dual-circuit, all wheel braking system. Full power hydraulic system actuates self-cleaning caliper disc brakes with independent front and rear circuits and accumulators.

Parking Brake
Fitted to the center axle in an elevated position, spring applied and hydraulically released.

Operator Comfort
Improved Productivity from a Confident Operator

Operator Comfort

Ride Comfort
The 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 Cab
The 725C features a large two-person cab, offering comfortable working space for both the operator and passenger with large storage compartments. The 730C, 730C EJ, 735B, 740B and 740B EJ 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.

Passenger Seat
Full-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 Column
A comfortable driving position is provided by a telescopic and tilt adjustable steering column.

Ease of Operation
Designed around the Operator

Ease of Operation

Ergonomic Layout
The 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 725C allow the operator to concentrate on production.

The 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), diff-lock, 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 rearview 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.

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 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 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
The four plate box constructed rear frame minimizes stress concentrations and provides low weight with long service life.

Dump Body
Extensive 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.

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
The two-piece construction of the hitch features a durable cast steel head bolted to a hard wearing forged steel tube.
