EH3500ACII

AC-drive system

Hitachi has been in the electrical drive system business for years – first with GTO, now with IGBT. In fact, the technology has successfully been used on bullet trains, locomotives, monorails and commuter electric cars around the world. With the EH3500ACII, Hitachi became the only truck manufacturer in the world to provide its own IGBT controller, alternator and wheel motors. The result is an AC-powered truck that is more productive, maneuvers easily in tight spaces and comfortably handles the haul road with steady speed on grade.

Tough body

The Hitachi horizontal stiffener design minimizes stress concentrations by dissipating load shocks over the entire body length. In addition, closely spaced stiffeners provide additional protection by minimizing distances between unsupported areas.

Brake blending

Brake blending, which combines service brakes with electric retarders, is applied automatically through the new AC drive system to stop the hauler. This also gives you the ability to stop the hauler with the retarder pedal only and acts as a hill-hold brake for sure hill-climbing.

Auto retarding control

The hauler’s auto retarding control keeps the vehicle’s downhill speed constant within the set range by limiting the maximum vehicle speed. An optional slip-slide control is also available by regulating the traction motor torque for stable travel.

Fast-fill system

The fast-filling system, a provided standard on the left side of the radiator, gives you direct access at the ground level for fast feeding of lubricants, grease, hydraulic oil and engine oil. Couplers are optional.

Load weighing system

The hauler’s payload-monitoring system is fully integrated to the monitoring system on the truck (and therefore your Mine Management System*) for prompt reporting of tons moved, cycle times, cycle count and distance.

*Requires optional equipment.

Easy access ladder

A new, easy-access diagonal ladder provides a safe, easy-to-use way to access the cab.
