Electric-drive haul truck

Hitachi is pleased to introduce its rigid-frame electric-drive EH4000ACII haul truck equipped with a front trailing arm and NEOCON-E suspension with the vertical integration of its own AC-Drive technology.

The brushless motors of the AC-drive system provides lower maintenance costs and trolley-assist options are available to help improve performance on grade and reduce fuel consumption.

The truck’s cab includes a newly designed air-ride seat and semi-active seat and the rig’s controller monitors truck systems and replaces multiple outsourced controllers. A simple flat-panel dashboard consists of a 26.4 cm LCD monitor that eliminates all independently placed gauges and lights.

Other new features include: planetary design with two fixed planetary gears; final drive with gear-oil circulation system; box design with sloped floor and tail chute for less spillage and smoother shedding of materials; load-weighing system with correction by axle/weight ration and slope angle for greater accuracy; easy-access front ladder; and a ground-level, fast-filling system for coolant, grease, and hydraulic and engine oil.
