Compact RadiusThe 325C LCR has been designed to rotate with a minimal amount of counterweighthanging over the tracks, which allows it to work in tight, confined areas.Productivity. Even though the 325C LCR has beendesigned for use in specific applications that requirehigh maneuverability in confined spaces, it stillmaintains the ability to accomplish tasks in a varietyof applications where space is not a factor.Swing Radius. The Caterpillar 325C LCR has a tailswing radius of 1900 mm as compared to 3050 mmfor the standard Caterpillar 325C L. This reductionof tail swing may allow for swing operation withgreater confidence knowing that the tail of themachine only has a minimal amount of overhang.The increasing need to work within space-restricted areas has createda demand for larger excavators that can also work within tighter quartersand provide greater productivity. The newest addition to this lineup ofCompact Radius (CR) excavators is the 325C LCR.AAA321C LCR21900 mm320C L2770 mm3050 mm325C LTail swing radius (mm)A Overhang (mm)with 600 mm shoeswith 800 mm shoeswith 850 mm shoesLift and Stability. The boom on the 325C LCRhas been moved more towards the center of themachine, this results in overall greater lift capacityover the front as compared to the standard 325C L.In addition to the repositioning of the boom,the Cat 325C LCR utilizes the undercarriageof the 330C L, which allows for an extremelystable operating platform.325C LCR1900320C L2770325C L3050305–18012801180–14551355–325C LCR versus 325C L.

Engine and HydraulicsThe Cat 3126B ATAAC engine and hydraulics give the 325C LCR exceptional power,efficiency, and controllability.Commonality. Many of the same provencomponents that are used in the Cat325C L are also utilized in the 325C LCR.This includes the same front linkageoptions, the powerful 3126B ATAACengine, HEUI fuel system and highperformance hydraulic system.Engine. Six cylinder turbochargedengine built for power, reliability,economy and low emissions will keepthe machine up and running. The Cat3126B ATAAC engine meets Stage IIworldwide emissions requirements.Automatic Engine Speed Control.The three-stage one touch controlmaximizes fuel efficiency and reducessound levels.Turbocharged and Air-to-air aftercooled.Turbocharger packs more dense airinto the cylinders for more completecombustion and lower emissionsimproving performance and engineefficiency. These benefits are especiallyuseful at high altitudes. Air-to-airaftercooler reduces smoke and emissionsby providing a cooler inlet air for moreefficient combustion. This also extendsthe life of the piston rings and bore.HEUI controls injection pressureelectronically. This unique capabilitymeans the regulation of injectionpressure is completely independentof crankshaft speed. Peak injectionpressure can be achieved underacceleration and lug conditions,providing better fuel economy,better response and reduced smoke.Hydraulic Cross Sensing System.Improves productivity with fasterimplement speeds and quicker, strongerpivot turns.HEUIInjection pressureHEUI Fuel System. In the traditionalcommon rail fuel system, the entire fuelline is under high pressure. With the HEUIsystem, fuel remains at low pressureuntil it is injected into the cylinder.Fuel pressure is created hydraulically inresponse to a signal from the ElectronicControl Module (ECM).ConventionalFuel SystemEngine speedInjection pressure in a HEUI fuel system isindependent of engine speed.Hydraulic Cylinder Snubbers.The hydraulic cylinder snubbers at rodend of boom cylinders and both endsof stick cylinder cushion shocks, reducesound, and increase cylinder life,keeping the machine working longer.Controllability. The hydraulic systemoffers precise control to the 325C LCR,reducing operator fatigue, improvingoperator effectiveness and efficiency,which ultimately translates intoenhanced performance.3
