The enhancedperformance of the Slip/Slide Control Systemcomes from the utilization of various newsensors on the front wheels, suspensionand steering systems.n Pitch control systemThe Pitch control feature of the AdvancedAC-Drive System reduces bouncing/rebounding on the truck as it hits bumpsor uneven ground on the haul road. As thetruck comes to a stop the rebounding orrocking effect due to the change in inertiaof the truck is also reduced.4n Side skid control systemThe Advanced AC-Drive System also providesa side skid control feature that helps theoperator in slippery road conditions whenmaking turns. By utilizing changes in thewheel motor torque from left to right duringcornering, it assists the operator in turningthe truck and keeping it on the proper track.

THE MOST ADVANCEDAC-DRIVE SYSTEM EVER.EFFICIENT AND INNOVATIVE.The EH3500AC-3 runs with Hitachi’s newest, state-of-the-art AdvancedAC-Drive System using Hitachi’s own IGBT controller, alternator and wheelmotors. Hitachi has been in the electrical drive system business for years – firstwith GTO, now with IGBT. In fact, the technology has successfully been usedon bullet trains, locomotives, monorails and commuter electric cars aroundthe world. The result is an AC-powered truck that outperforms other systemsthrough its simplicity, efficiency and dependability.Hitachi is the only truck manufacturer in the world that builds its own ACdrive systems. So the new Advanced AC-Drive System is perfectly matchedto the EH3500AC-3. It delivers higher torque, faster acceleration, smootherretardation and lower operating costs. With the Hitachi Advanced AC-DriveSystem, you get POWERFUL TECHNOLOGY.n Auto cruise control keepsvehicle speed constant within theset range by limiting the minimumvehicle speed.n Auto retarding control keepsvehicle downhill speed constantwithin the set range by limitingthe maximum vehicle speed.n Superior electric brakingenables the driver to stop thetruck using the electric brakepedal only with the exceptionof emergencies, because theAC-drive control system appliesthe service brakes automaticallyjust before the stopping, resultingin easy machine operation andlonger time between servicebrake maintenance intervals.n IGBT modules (inverter andchopper) are liquid cooled.Grid resistors, alternator andtraction motors are forced-aircooled. The final drive gear oilis circulated, air-cooled andfiltered before being directedback to the final drive.n AC-drive wheel motorThe Hitachi Double Path TandemPlanetary Design provides highefficiency. Better componentand lubricant life is theresult of holding the 1stcarrier stationary andconstantly cycling thelubricant through acooler and filter.5

EH3500AC-3EH SERIES AC-DRIVE MINING TRUCKSBUILT TO TACKLETOUGH JOBS.OUTPERFORM. OUTLAST.Hitachi trucks have earned a reputation for durable and dependableperformance at mining operations across the world. The EH3500AC-3is no exception and tackles your toughest jobs with its redesigned frame.Its unique trailing-arm suspension minimizes frame stress and fatigue,while providing lower tire wear and better steering. This rugged system iseasy to service and maintain. You get access to the strut without removalof the wheel, which reduces your downtime and repair costs. With theEH3500AC-3, you get MORE WORK DONE.n The updated body isstiffer and tougher with a sixpercent steeper floor pitch toreduce spillage and providesolid, well cushioned bodyto-frame support. The hoistsystem is auto-programmedto stop before stroke end toreduce shock.n Our new cab structureprovides improved safety anddurability. The cab frame isstronger and features a threepoint isolation-mount designto allow additional independentmotion from the truck frame.n The redesigned frame alsofeatures a bolt-on, high-archcross member, combinedwith a new rear axle housingand nose cone design thattogether deliver higherstrength and durability.n The new frame has fullyfabricated box-section railswith section height taperedfrom rear to front. The onepiece top and bottom flangeseliminate cross membertie-in joints. The large radiiat frame junctions minimizestress, and all welds arelongitudinal to reduce stresscracks and deliver morestrength and durability.
