Cat C7 Engine with ACERT TechnologyACERT Technology incorporates a series of innovations working at the point of combustionto optimize engine performance while providing high reliability and easy servicing.

Cat C7 Engine with ACERT Technology.The C7 engine provides a full-rated grosspower (SAE J1995) of 149 kW (202 hp) at 2200 rpm with a torque of 783 Nm.Meets European EU Stage IIIA engineemission regulations. The combination of large displacement andhigh torque allow the AP755 to performunder the toughest conditions.

HEUI™ fuel injection. The hydraulicallyactuated electronic unit injectors (HEUI)fuel system is unique and combines thetechnical advancement of an electroniccontrol system with the simplicity of HEUIfuel injection. The HEUI fuel system excelsin its ability to control injection pressureover the entire engine operating speedrange. These features allow the C7 engine to have complete control over injectiontiming, duration and pressure.

Multiple injection fuel delivery. Multipleinjection fuel delivery involves a highdegree of precision. Precisely shaping thecombustion cycle lowers combustionchamber temperatures, which generatesfewer emissions, optimizes fuel combustionand translates into more work output foryour fuel cost.

Turbocharged and Air-To-AirAftercooling (ATAAC). Theturbocharged air-to-air aftercoolingsystem provides high horsepower withincreased response time while keepingexhaust temperatures low for longhours of continuous operation. Air-to-air aftercooling keeps air intaketemperatures down, maximizing fuelefficiency and minimizing emissions.

High cylinder pressures. High cylinderpressures combined with tightlycontrolled tolerances promoteextremely efficient fuel burn, less blow-by and lower emissions.

C7 cylinder block. The C7 engine’scylinder block offers increased tensilestrength. It features improved sealingwith gaskets to ensure fewer leaks. This new design supports the engine’shigher compression ratios and increasesits power density. The incorporation ofstraight-thread “O” ring connectionpoints reduce the loss of engine oil andfluids.

Sound reduction features. The C7engine sound reduction features includecomposite valve covers with a fullyisolated base, a steel oil pan and a castiron front cover. The HEUI™ fuelsystems rate-shaping technology alsoprovides control of sound and vibrationlevels.

Service, maintenance and repair.Easier service, maintenance and repairis accomplished by monitoring keyfunctions and logging criticalindicators. Advanced electronicdiagnostic capabilities are possibleusing CAT Electronic Technician.

ADEM™ A4 electronic control module.The ADEM A4 electronic controlmodule manages fuel delivery, valvetiming and airflow to get the mostperformance per liter of fuel used. The control module provides flexiblefuel mapping, allowing the engine torespond quickly to varying applicationneeds. The control module alsomonitors engine and machineconditions while keeping the engine at peak efficiency.

Cooling system. The high capacitycooling system provides efficientoperation in high ambienttemperatures. The system promotesoperator comfort by drawing ambientair through the engine compartmentand exhausting it on the right side ofthe machine, away from the operator.

UndercarriageThe steel track undercarriage provides optimum weight distribution, tractive effort assuringgreat performance.

Two rubber shoe crawlers. The track-type asphalt paverprovides a reliable, smooth ride. The optimum tension of thetracks is assured by a grease piston with a shock absorbingsystem.

Bonded track pads. The track pads contain a special rubbercompound in order to provide long life and optimum traction.Pads are attached with four bolts for easy replacement.

Two-speed planetary drive. Two fixed displacement motorsdrive two-speed planetary track drive gearboxes in order toprovide infinitely variable speed selection.

Propel SystemEfficient hydrostatic propel system eliminates chains and other mechanical linkagesbetween the engine and final drive components.

Closed-loop hydrostatic propel system. Provides accuratecontrol of propulsion and low-maintenance operation.

Hydrostatic pumps. Two variable displacement, hydrostaticpumps are driven by the diesel engine and drive two fixeddisplacement motors. Pumps are infinitely variable andelectronically controlled for starting and stopping ramps.

Speed control. Infinite speed selection within two propelranges: one in working mode and one in travel mode, to selectthe best speed range according to operating modes.

Propulsion control. An electro-proportional servo-controlprovides machine starting and stopping (for asphalt supply,etc.) with no pre-set working speed variation.

Mechanical benefits. Because the system is completelyhydrostatic, there are no mechanical linkages such as gearcases, transmissions or chains between the engine power take-off and the drive system. This results in a significantreduction in mechanical parts and less chance for mechanicalfailure.

Operator’s StationThe dual operator stations provide complete control and optimum visibility from either sideof the operating platform.

Dual operator stations. The ergonomic dual operator stationsincorporate two adjustable suspension seats fitted onmechanically sliding semi-platforms.

Enhanced visibility. Both operator seats and console panel aremounted on pivoting pedestals enabling the operator to rotateeither to the left or right. The stations can extend beyond themachine frame for optimum visibility when joint matching orwhile paving other applications where precise control isrequired. With the engine mounted forward and low in frame,the operator is positioned away from engine heat and exhaust.

Control console. The sliding operator’s console panel is fullyequipped with comprehensive controls allowing the operator to conveniently monitor all machine functions. A multifunctional LCD-display fitted to the console panelprovides detailed information regarding the operating para-meters of machine and engine. A lockable vandal coverprotects console controls.

Canopy option. Two optional canopies are available: foldingcanopy or hydraulic raising canopy. Both canopies provide full width with two side extending wings for optimum comfort and protection. Canopies can be lowered (manually or hydraulically) for easy transportation.

Material Handling SystemPrecise mix delivery and productivity through an advanced material handling system.

Hoppers. The independent movement of thetwo hoppers is provided by means of twohydraulic cylinders assuring efficientmaterial flow. Wear-resisting steel providesconveyors and hopper bottom plate for longwear life.

Feeding conveyors. Two feeding conveyorsare independently controlled andproportionally driven by two ultrasonicsensors. Conveyor rotation can also beinverted from either operator’s console panelor from rear screed control boxes. Conveyors have drive chains to maximize the live conveyor area and reduce center linesegregation. This design also provides greaterease of servicing the conveyor drive system. In order to control mix delivery, theoperator sets a speed rate for each conveyorthat will maintain the desired mix level inthe left and right auger chambers.

Optimum productivity. The materialhandling system allows the operator tomaintain an uninterrupted flow ofmaterial from the hoppers to thescreed. The system is responsible formaintaining the proper head ofmaterial - the volume of asphalt infront of and across the length of thescreed.

Auger assembly. Two independentlycontrolled augers spread the materialconveyed to both sides. Auger rotationspeed can be varied automatically toensure a homogeneous distribution ofmaterial before the screed. Two ultrasonic wave detectors controlproportional augers movement and can be adjusted from the screed control boxes.Conveyors and augers design eliminatevoids under chain case to minimizesegregation.Augers have outboard mounted motorsfor easy serviceability.

Adjustable height auger assembly.Augers are reversible andhydraulically adjustable in heightproviding benefits to mat quality and better distribution of material in front of the screed. The ability to raise the auger assemblysimplifies loading and unloading froma transport vehicle. Also, whenworking with larger stone mixes,segregation can often be eliminated or minimized by raising the augers toallow mix to flow unrestricted underauger assembly.
