MOLINE, Illinois — Hitachi rigid-frame trucks set the standard for productivity and comfort. After several months of field testing, the company’s newest model — the electric-drive EH4000ACII — is ready to roll. It combines Hitachi’s time-honored front trailing arm and NEOCON-ETM suspension system with the vertical integration of Hitachi’s own IGBT AC-Drive technology. The result is a smooth-steering, smooth-riding, highly dependable, and long-lasting haul truck that mining operations will appreciate.

Because it utilizes AC-drive technology, the EH4000ACII has lower life-cycle costs and better performance on grade uphill or downhill with superior rimpull and retarding capabilities. The brushless motors of the AC-drive system provide lower maintenance costs while providing increased uptime. Trolley-assist options are available to improve performance on grade by increasing productivity while reducing fuel consumption during the haul cycle.

The EH4000ACII maneuvers easily in tight spaces and comfortably handles the haul road with steady speed on grade. Turning diameter is 30.2 m (99 ft. 1in.).
