More hydraulicpower means better overall components mean fewerhydraulic connections and reducedchance of 8 Low Effort Machine , pilot hydraulic controlsgive operators precision control of theCat Multi Terrain Loader with minimaleffort. The right joystick controls loaderup/down and tilt control and the leftjoystick controls forward and reversetravel speed plus direction. Both joysticksuse an intuitive S control deluxe joysticks now providemore auxiliary controls than before,using positive-action buttons to provideprecision fingertip control of manymachine functions, including: Proportional work tool hydraulics Work tool electrical Basic and Deluxe joystick functionsinclude: One-touch continuous auxiliaryhydraulic flow Momentary auxiliary hydraulic flowCab hours in theCat Multi Terrain Loader are madeeasier by many standard conveniences,including a 12 volt DC power , sliding windows offer protectionfrom the elements and allow fresh airventilation.

4 Redesigned side windowsare removable for easy with the door option installedfeature a new, automatic lock-outswitch that prevents accidental damageby disabling the loader functions whenthe door is Climate in extreme temperatures canbe more comfortable with the optionalcab air conditioner and heater is increased up to 83 percentand is now directed through six adjustablevents. Twice as many vents makesdefrosting the optional front door andside windows easier. The heater and airconditioner can be ordered separatelyor Multi TerrainLoader instrument panels and gaugesare simple, easy to use and indicator lights and audiblewarnings signal any critical systemsituation. Positive feel switches,with status lights, control most on/offfunctions.

5 An engine air cleanerrestriction indicator is now in thecab for easier operator station provides exceptional working comfort with excellent visibility,enhanced fingertip controls and optimum StationOperator Station ease and productivityis enhanced on the Cat Multi TerrainLoader with excellent visibility. Thewide cab opening offers an exceptionalview of the work tool. The sloped angleof the engine compartment allowsexcellent visibility to the rear of themachine. A new, convex rearviewmirror option gives the operator apanoramic view of the machine srear and sides. In addition, for bettervisibility in low-light conditions,the standard forward lights are nowadjustable 10 degrees in any Cat Multi TerrainLoader cab is designed to make machineoperation simple, productive andcomfortable.

6 Getting in and out of thecab is easy through a wide opening withthree point grab irons and skid-resistantsteps. Tilt cylinders are neatly locatedunder the lift arms so not to interfere withoperator access and egress. Plenty ofuncluttered floor space makes steppinginto the cab even cab packagesand options are available. The standardcab offers features such as an adjustablecontoured seat, cushioned contouredarmbar, dual throttle controls, pilotoperated joysticks, 12 volt DC powersocket and optional cup Visibility Rubber Track rubber track undercarriage transfersmachine weight to the ground through24 wheeled contact points. Machineweight is evenly distributed throughoutthe Contact large groundcontact area helps maximize tractionand minimize ground Track elevated,internal positive track drive keeps drivecomponents away from ground Rubber rugged,durable rubber track is lightweight andpliable, yet reinforced with high tensilestrength , torsionaxles suspend each side of theundercarriage from the machineframe and are Track UndercarriageThe unique rubber track undercarriage provides low ground pressure, stability,high traction, fast travel and Track Undercarriage 7 Cat Diesel heart of theCat Multi Terrain Loader power trainis the Caterpillar 3024C Turbo dieselengine.

7 This rugged, reliable, four cylinderengine offers aggressive performanceand a fast torque curve for quick is also a low emission engine, EPA Tier 2 Engine Throttle handand foot throttles allow the operator tomatch engine speed to the task. The handthrottle is ideal for jobs requiringconsistent engine speed such as coldplaning, trenching or snow foot throttle lets the operatorvary engine speed and minimize fuelconsumption for other tasks such asload and carry, truck loading, gradingand anti-stallsystem on the Cat Multi Terrain Loaderallows maximum power to the trackswhile minimizing engine system helps maximize productivityfor experienced operators and makesit easier for novice operators to , High Output dual, closed-loop, axialpiston hydrostatic pumps are drivendirectly off the engine.

8 The pumpsprovide pressure and flow to two fixeddisplacement motors that power thefinal drive motors, driving the chains are Performance Power TrainCaterpillar hystat power train delivers aggressive performance and easy Performance 8 Power and powerand reliability are built into the CatMulti Terrain Loader hydraulic addition to providing power to drivethe tracks, this system also provides theloader lift and tilt functions, powers theauxiliary circuit to drive work toolsand drives the engine cooling hydraulic pumpsare driven off the engine for maximumhydraulic performance and reliability no belts are used. Pumps are fixed-displacement and provide 60 L/min( gal/min) at high idle. Maximumsystem pressure for the loader andauxiliary circuit for the 247b and 257 Bis 23 000 kPa and 3335 psi.

9 Two fixeddisplacement gear pumps provide flowand pressure for the 257B high flowloader and auxiliary circuit at 100 L/min(26 gal/min) at high idle. Maximumsystem pressure for the loader andauxiliary circuit is 23 000 kPa (3335 psi).Control of the loader lift and tiltfunctions is by hydraulically-operatedjoystick controls for low effort andprecise auxiliaryhydraulics to power work tools isavailable through quick connect hydrauliccouplings that are rigidly mounted tothe loader arm. The Caterpillar line ofXT ES hoses and O-ring face sealshelp assure a leak-free and reliability and cleanliness areimproved by using single componentsin place of multiple components, suchas the monoblock hydraulic valve andmonoblock pumps.

10 Fewer leak pointsimprove reliability and result in acleaner machine. In addition, hydraulicoil flows through a 5-micron spin-onfilter. A filter restriction indicatoris located at the operator screen in the hydraulictank prevents larger debris fromentering the system and causingdamage to the hydraulic Oil high-efficiencyhydraulic oil cooler lets the Cat MultiTerrain Loader work longer and harderin higher ambient temperatures, evenwhen using continuous high flow worktools. The high capacity hydraulic oilreservoir also helps keep operatingtemperatures hydraulic system has built-in reliability and provides exceptional lift, breakout andauxiliary power to work Hydraulic SystemPowerful and Reliable 9 Lift loader lift arms are purpose-designed to provide a substantiallystraight load path into the machine anda good viewing area to the work tooland sides of the machine.
