WHEEL LOADER - Hitachi Construction Machinery

With Emphasis onFunctional BeautyPractical Compact-Wheel LoaderPleasantto DriveThe ZW Compact Series features comfortableand reliable Compact-wheel loaders for usein a wide variety of fields. The strong andindividual body of these Compact-machines wasdesigned with functionality and mobility in mind.The graceful silhouette is a result of thoroughresearch into the full range of basic functions.Try the ZW Compact Series of wheel loadersequipped with a diverse range of high-qualityfunctions demanded of versatile Compactmachinery,including comfortable operability,high-level safety, easy maintenance andenvironmentally friendly design.The new engine complieswith the Emission RegulationsU.S EPA Interim Tier 4 andEU Stage III AThe advanced low noisedesign complies withthe coming EU noiseregulation 2000 / 14 / EC,STAGE IINote: The illustrations and photos used in thisbrochure include optional equipment.

Subtle Functional Beauty for Greater Work PerformanceHeavy load performance that supports powerful digging, excellent stability, and strong traction force.Steering performance that improves work efficiency in tight job site. All part of greater work performance.Excellent StabilityHigh-Powered EngineHighly Original Large CounterweightThe use of a large counterweight lowersthe center of gravity and protects thebody, as well as improves stability.Easy-to-Use Towin PinBy lowering the towin pin position, thetroublesome need to raise loads bystraining on a heavy wire rope has beeneliminated, enabling much more stabletowin performance.The high-powered engine, mountedon the ZW40 or ZW50, allows formore powerful, smoother operationwith less fuel consumption evenat low engine rpm, assisted by its new4-cylinder configuration with increaseddisplacement and suppressed vibration.Reinforced MainframeWe have carefully researched the center of gravity to maintain the weight balancebetween the front and rear, upper and lower, and left and right of the machine so thatnot only is excellent stability maintained.Great Dumping Clearance and ReachSmall Turning Radius for Tight SpacesDumpingClearanceZW30ZW40ZW50DumpingReachDumpingClearance2 155 mm2 445 mm2 500 mmDumpingReach775 mm800 mm870 mmAchieves ample dumping and reach.Dumping into a hopper or loading intoan 11 t dump truck is possible due tothe excellent stability.ZW30ZW40ZW50Total Length(in Driving Mode)4 165 mm4 460 mm4 630 mmTurningRadius3 550 mm3 740 mm3 815 mmNote: The turning radius is the value of theoutermost bucket.In order to improve turning performance,such as the distance and position fromthe front axle to center pin and centerpin to rear axle, great improvementshave been made to this latest model.In this way, the Compact-wheel loaderis now easier to use in town and citystreets and other confined work spaces.To reinforce the front and rear frames,a box-section structure has beenintroduced. This improves durability,which results in greater reliability.

Functional Beauty That Promotes Skillful Operationand ComfortCan be operated skillfully by operators without great experience.Further, this quiet and comfortable operating environment is part of basic ZW concept.HST Auto TransmissionContinuously adjustable speed can beachieved by operating the accelerationpedal - enabling start, acceleration, andstopping to be performed automatically.Travel is made easy with smoothautomated speed changesPrecision operations possible usingextremely low speedsExcellent mechanical operations withhighly responsive accelerationSmooth startup on inclines using HSTbrake operationsExcellent rim pull at all speeds rangeSimple and Secure Front Control LeverPanoramic Cab for Good Field of Vision (Optional)Sun Visor (Optional)Suppresses glare from thesnow and sun.AM/FM Radio + 2 Speakers(Optional)A secure and easy-to-use front operationlever that controls the lifter smoothly andspeedily.Suspension Seat(Optional)A suspension seat is availableto lessen vibrations and shockduring operation.Convenient Forward and Reverse LeverSwitch easily between forward andreverse operations using the fingers ofyour left hand while holding onto thehandle.Good Visibility MonitorSpecial Handrail and Large Step forMounting and AlightingComfortable Seat to Reduce FatigueUses a large sliding sash for the door and a pillar-less designgives an unobstrusted view of the front. The cab enablespanoramic views via the addition of a lower window, which wasabsent in existing models, the removal of the rear corner pillar,and the use of a new and improved defroster nozzle,etc., providing a wide field of vision.An easy-to-read transparent meter panelenables you to determine the machine'sstatus at a glance. Instruments feature acompact layout for easy checking.Walkthrough Type CabinA walkthrough type cabin enablesmounting and alighting from either theright or left.There are handrails and large stepsmounted on both the left and right of thecabin for easy access.Electric Switch Parking Brake thatPrevents Pulling Friction DamageSuppresses scorching due to pullingfriction. Further, when the engine isstopped, the brake is automaticallyapplied.A comfortable seat to relieve operatorfatigue has been adopted. Absorbsunpleasant vibrations, reducespsychological and physical burdens,and reduces fatigue due to long timeoperations.Glove Box BehindSeatA convenient glovebox is locatedbehind the seat forstoring documents,etc.Quiet Cab InteriorQuiet interior design for operator comfort.Cab interior noise has been greatlysuppressed to achieve quiet travelingrubber-mounted hydraulics, a tightly-sealedcan operator frame anda new low-noise engine.

Functional Beauty Safety and EnvironmentallyFriendlyAchieving a high-level of safety in the working environment with an array of advanced mechanisms.Functional Beautyto Reduce CostsCentralized Rear MaintenanceIn pursuit of functional beauty, models featuring this new design are not just beautiful,but also easy and reduced running costs.Full-Open Cover Easy Day-to-Day InspectionsHN Bush* Extends Lubrication IntervalsGreasetroughHN bushes boasting superior lubricationcharacteristics are used in the loaderjoints to extend the lubrication interval to250 hours.Note: For the lubrication interval from the start ofoperation to 50 hours, refer to the user manual.Improved Cab CleaningROPS* / FOPS** Cab (Optional)The ROPS / FOPS cab is provided toprotect the operator from injury in anaccident.* ROPS: Roll-Over Protective Structure: ISO3471** FOPS: Falling-Object Protective Structure: ISO3449Neutral Engine Start Mechanism toImprove SafetyUnless the forward and reverse lever isin neutral, this safety feature inhibits theengine from being started.Lever LockKey Lock to Prevent VandalismThis key lock prevents damage causedby vandalism to the fuel inlet cap andengine cover.Reduced Environmental ImpactSubstancesAluminum RadiatorLead-Free WiringDaily maintenance is even easier with the incorporation of a large full-open cover andlowest counterweight. The cover opens at a touch, and is supported by tow gasdampers. The engine room, which can be fully open, enables maintenance such asinspections, replacements and filling to be carried out with ease.Replacement Friendly Filter LayoutCompact Electrics LayoutElectrical device relays are locatedtogether for easy maintenance.Easy Remote LubricationThe area around the door has beenredesigned to produce a flat, even floorinside the cab. This allows for easy ofcleaning.This safety mechanism locks the frontcontrol lever. Lever locks can be fittedoptionally to third function levers.The layout enables easy replacementof the fuel and hydraulic systemfilters. These fuel filters are integratedcombining water separator functions.The filters, including the engine oiland operating oil tank return filters,are cartridge type filters for easyreplacement.Lubricator(Grease nipple)Remote tubeSuspensionBecause the rear suspension can belubricated remotely, there is no need tocrawl under the machine to performthis task.
