C13 Engine with ACERT™ TechnologyBuilt for power, reliability, economy and low emissions.

Performance. The 345D L, equippedwith the C13 with ACERT™Technology provides 18% more powercompared to the 345C L. The buildingblocks of ACERT Technology are fueldelivery, air management, andelectronic control – providing betterfuel economy and reduced wear.

Fuel Consumption. The ADEM™ A4electronic control module manages fueldelivery to get the best performance perliter or gallon of fuel used. The enginemanagement system provides flexiblefuel mapping, allowing the engine torespond quickly to varying applicationneeds. It tracks engine and machineconditions while keeping the engineoperating at peak efficiency.

Low Sound and Vibration Levels.The engine mounts are rubber-isolatingmounts matched with the enginepackage to provide optimum sound andvibration reduction. Further noise

reduction has been achieved throughdesign changes to the isolated top cover,oil pan, multiple injection strategy,insulated timing cover and sculptedcrankcase.

Emissions. The 345D equipped with theCaterpillar C13 engine can meet EUStage IIIA or EU Stage II emissionsrequirements.

Fuel System. The Cat® C13 featureselectronic controls that govern themechanically actuated unit fuelinjection (MEUI) system. MEUIprovides the high-pressure required tohelp reduce particulate emissions anddeliver better fuel economy throughfiner fuel atomization and morecomplete combustion.

Cooling System. The 345D L layoutcompletely separates the cooling systemfrom the engine compartment. Thecooling fan is hydraulically driven withvariable speed control based on the

ambient temperature, coolanttemperature, and hydraulic oiltemperature. This unique feature assistsin the management of engine power andimproves noise efficiency whileproviding optimized cooling.

Air Cleaner. The radial seal air filterfeatures a double-layered filter core formore efficient filtration and is located in a compartment behind the cab. A warning is displayed on the monitorwhen dust accumulates above a presetlevel.

Turbocharger. The Cat C13 engine usesa wastegate turbocharger for improvedperformance.• The wastegate valve controls

excessive engine boost pressure byallowing exhaust to bypass theexhaust-side turbine.

• The wastegate also reduces turbinewear in high RPM, low loadconditions and optimizes air and fueldelivery for peak engine performance.

• The turbocharger increases thedensity of the air, enabling the engineto produce more power with feweffects from altitude.

Power Management Modes.The Power Modes are selected from themonitor menu. They allow selectingoptimal machine performances for eachtype of application.• High Power Mode is recommended

for applications where highproductivity is essential or for harddigging applications.

• Power Management Mode is forapplications requiring similarperformance as 345C L, but withbetter fuel efficiency.

• Economy Mode is for applicationswhere fuel economy is a priority overproductivity.

The Power Management Mode andEconomy Mode performances areachieved through finely tuned hydraulichorsepower and engine RPMmanagement.

SmartBoom™Reduces stress and vibrations transmitted to the machine.

Rock Scraping. Scraping rock andfinishing work is easy and fast.SmartBoom™ simplifies the task byallowing the operator to fullyconcentrate on stick and bucketmanipulation, while the boom is free tomove up and down without usingimplement pump flow.

Hammer Work. SmartBoom is operator-friendly and increases productivity inhammering applications. The front partsautomatically follow the hammer whilepenetrating the rock. Blank shots orexcessive force on the hammer areavoided resulting in longer life for thehammer and the machine. Similaradvantages are applicable when usingvibratory plates.

Truck Loading. When using SmartBoom,loading trucks from a bench is moreproductive and more fuel efficient as thereturn cycle is reduced while the boomdown function does not requireimplement pump flow.

HydraulicsCat hydraulics deliver power and precise control to keep material moving.

Pilot System. The pilot pump isindependent from the main pumps andcontrols the front linkage, swing andtravel operations. The pilot controlvalve operation is proportional tocontrol lever movement, deliveringoutstanding controllability.

Component Layout. The componentlocation and hydraulic system designprovide the highest level of systemefficiency. The main pumps, controlvalve and hydraulic tank are located asclose to each other as possible. Thisdesign makes it possible to use shortertubes and lines between components,reducing friction losses and pressuredrops.

Heavy Lift Standard. The operator canselect the heavy lift mode at the push ofa button to boost lifting capability andprovide improved controllability ofheavy loads.

Hydraulic Cross-Sensing System. Thehydraulic cross sensing system utilizeseach of two hydraulic pumps to 100percent of engine power under alloperating conditions. This improvesproductivity with faster implementspeeds and quicker, stronger pivotturns.

Boom and Stick Regeneration Circuits.A hydraulically operated stickregeneration circuit saves energy andimproves multi-function performanceduring the stick-in operation. New onthe 345D L, the boom regenerationcircuit is operated electrically, managedby the machine ECM. The systemimproves cycle times and fuelefficiency, increasing your productivityand reducing operating costs.

Boom and Swing Priority. Thehydraulic system on the 345D Lprovides automatic priority function forboom-up and swing operationseliminating the need for work modebuttons. When the boom or swing leveris activated, the system automaticallyassigns priority based on operatordemand.

Hydraulic Cylinder Snubbers. Snubbersare located at the rod-end of the boomcylinders and both ends of the stickcylinders to cushion shocks whilereducing sound levels and extendingcomponent life.

Auxiliary Hydraulic Valve. Ahydraulically controlled auxiliary valveis standard on the 345D L. Controlcircuits are available as attachments,allowing operation of high and mediumpressure tools such as shears, grapples,hammers, pulverizers, multi-processorsand vibratory plate compactors.

Windows. All glass is affixed directlyto the cab, eliminating window framesand providing excellent visibility. Theupper front windshield opens, closesand stores on the roof above theoperator with a one-touch action releasesystem.

Wipers. Pillar-mounted wipers increasethe operator’s viewing area and offercontinuous and intermittent modes.

Monitor. The compact, full colorgraphical monitor, displays machinemaintenance, diagnostic and prognosticinformation, in twenty-seven differentlanguages. The monitor angle can beadjusted to minimize sun glare.

Cab Exterior. The exterior design usesthick steel tubing along the bottomperimeter of the cab, improving theresistance of fatigue and vibration. Thisdesign allows the FOGS to be bolteddirectly to the cab, at the factory or asan attachment later, enabling themachine to meet specifications and jobsite requirements.

Cab Mounts. The cab shell is attachedto the frame with viscous rubber cabmounts, which dampen vibrations andsound levels while enhancing operatorcomfort.

Travel Controls. The 345D L uses pilotoperated control levers, positioned sothe operator can operate with arms onthe armrests. The vertical stroke islonger than the horizontal stroke,reducing operator fatigue. The controllever grips are shaped to fit into theoperator’s hands. The horn switch andone-touch low idle switch arepositioned on the left and right grip.

Operator StationDesigned for simple, easy operation, the 345D L allows the operator to focus on production.
