True “on-the-go” Automatic Traction Control (ATC).
Strong, durable Cat C13 ACERT engine platform with U.S. EPA Tier 4 Final/EU Stage IV exhaust emission solution.
Advanced Productivity Electronics Control Strategy (APECS) delivers a smooth shifting transmission, improving acceleration with higher productivity.
- Engine Model Cat® C13 ACERT™
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
Mechanically 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.
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.
Engine Compression Brake
The Cat C13 ACERT engine compression brake improves retarding response and increases retarding power.

- Transmission
Electronic Transmission
The Cat CX31 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.
The Cat C13 ACERT engine coupled with the CX31 transmission deliver increased forward and reverses rimpull. Featuring:
1. 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.
2. Critical gearshifts maintain direct drive lock-up, and eliminate dropping into converter drive. This maintains ground speed during shifts on grades.
3. The transmission automatically modifies shift points to best suit operating conditions.
4. Retarding levels are automatically reduced on lesser grades in lower gears.
Torque Converter
A large diameter torque converter, configured for off highway applications, allows the engine power to be transmitted more efficiently to the lower power train.
- 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
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
Dash
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.
- Ejector Body
Versatility
The 730C EJ shares the versatility of the Standard 730C Articulated Truck, operating in the same conditions but offering unique capabilities that stretch the operation envelope.
Spreading
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.
Stability
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.
Overhead Clearance
The truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations.
Carry-Back
The body design eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.
Blade
The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.
Cylinder
A three-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and smooth load ejection.
