Built with the power of efficiency

When you want a large capacity truck but not large operating costs, the EH4000ACII is a perfect fit. It combines Hitachi’s time-proven hauler technology with our high-power, high-efficiency IGBT AC-Drive system. It’s one of the most reliable mining trucks on the market, and it helps raise profits by lowering fuel and maintenance costs.

Product highlights

  • Load height and body volumes
    • Standard body 6.09 m (20 ft. 0 in.)
    • Struck (SAE) 106 m3 (138.6 cu. yd.)
    • Heaped 2:1 (SAE) 153 m3 (200.1 cu. yd.)
  • New Hitachi AC-drive system delivers better performance, higher uptime and helps significantly reduce maintenance and fuel costs.
  • The Cummins QSK60C diesel engine generates 1864 kW (2,500 hp) at 1,900 rpm and meets EPA Tier 2 emission requirements.
  • Quick stopping power. A service brake-blending feature activates the hydraulic service brake to quickly bring the hauler to a complete stop.
  • Cab helps increase operator productivity with more comfort/ease-of-use features, including a 3-point rubber ISO-mount that minimizes vibrations.
AC-drive system

AC-drive system

Hitachi AC drive technology provides superior truck performance with higher top speeds, better gradeability and stronger retardation.  Hitachi inverter modules provide high rigid truck controllability and efficiency. The Hitachi AC wheel motors do not have commutators and brushes, which improves truck performance by providing reduced maintenance costs, higher truck availability and higher travel speeds. These advantages result in more productivity and lower costs per ton. Hitachi AC drive systems also power electric train locomotives worldwide.

Auto cruise / retarding control

Auto cruise/retarding control

Auto cruise control keeps vehicle speed constant within the set range by limiting the minimum vehicle speed.  Auto retarding control keeps vehicle downhill speed constant within the set range by limiting the maximum vehicle speed.

Slip/Slide Control

Slip/slide control

The Slip/Slide control feature of the Hitachi AC Drive System, acts as an Active Traction Control and Anti-Lock Brake System in slippery conditions.  Utilizing information on wheel torque from the rear axle the Slip/Slide control system senses the differences in wheel speed and reduces wheel torque on the required side to act as traction and braking control in slippery road conditions.

Redesigned frame

Redesigned frame

The fully fabricated box-section main rails feature section height that is tapered from rear to front. This produces a narrower area at the rear to support the load and a wider area at the front to provide overall stability. One-piece top and bottom flanges eliminate cross-member tie-in joints and provide a large exposed center area for access to major components. The large radii at frame junctions are blended and ground stress concentrations are minimized.

Bolt on High Arch frame

Bolt on high arch frame

Newly designed bolt on style for high-arch cross member reduces assembly time and increases frame support for cab and deck area. This new design allows for faster assembly time vs. the weld on high-arch design of the previous model. Reducing time required for setup, welding, and inspection of the assembly of the frame in the field.

Superior Suspension

Superior suspension

The Hitachi trailing arm suspension system delivers excellent maneuverability, even at higher speeds.  The trailing arm layout offers greater ease of servicing while improving truck performance compared to suspended king-pin designs. The pivot mounting of the trailing arm design allows only axial input to the strut and allows wheel movement to the vertical plane only. 

Features:

  • Lateral forces that act on the front wheels are minimized, resulting in reduced tire scuffing.
  • Dynamic friction (side-wall force) within the strut is low due to the features of the trailing arm suspension design, allowing the use of a lighter strut engineered to a smaller diameter and longer stroke. 
  • The necessary frame bulk (horsecollar structure) needed to mount a suspended king-pin is non-existent.
  • The elimination of the “horse-collar” member provides greater engine access.

The NEOCON strut used with the trailing arm suspension, improves operator and component isolation, provides better hauler stability and predictable operational control.

  • Locating the king-pin close to the wheel assembly and at a slight angle results in low “Dry Park Steering” effort.
  • Development of the compressible media, NEOCON- E™ fluid (proprietary, silicone based, environmentally friendly) for use in the suspension strut with Helium gas, results in an improved energy absorption (isolation) system and an improved energy release (stability) system that responds favorably whether traveling empty or loaded in a wide range of ambient temperatures.

The trailing arm suspension design allows the front struts to be removed and installed without removing the front brakes or tires. This means fewer tools and less labor time are required, resulting in less downtime and higher productivity.

HI-TECH ROPS/FOPS Cab

HI-TECH ROPS/FOPS cab

The new HI-TECH ROPS/FOPS cab has been newly equipped with a Hitachi controller and a large centrally mounted, color Liquid Crystal Display (LCD) as used in Hitachi large sized excavators. Double wall construction of 11 gauge inner and outer steel panels produces a more structurally sound cab. A three point rubber isolation-mount arrangement minimizes vibration to the operator compartment.

Tough body

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.

Load weighing system

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.

Fast-fill system

Fast-fill system

The fast-filling system, 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.

Easy access ladder

Easy access ladder

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