EH5000AC-3 Hitachi EH5000AC-3 Specifications & Technical Data (2016—2026)

System to Improve Safety

The dump truck Aerial Angle system is designed to assist in preventing collisions with obstacles. Aerial Angle has been newly implemented as an advancement and addition to the previous Peripheral Vision system. Obstacles within the front and surrounding areas of the machine are detected with warnings being activated by the system. The dump truck Aerial Angle has two modes: Stationary Mode and Forward Mode. Stationary Mode detects any obstacles within the vicinity when the machine is stationary during dumping, loading, or when it is parked. Forward Mode warns the operator of the possibility of collisions during forward travel.

Stationary Mode

The display layout of the previous Peripheral Vision system has been improved and now includes an additional screen (a total of six screens). This provides greater convenience, allowing views to the sides as well as a birds-eye view of the machine itself. The camera places markers on the screens as it detects obstacles before operating. Red markers indicate any obstacles in the immediate vicinity of the machine, whereas yellow markers indicate obstacles further away. The markers will continue to follow obstacles until they no longer appear on the screen and have been avoided. This system enables the operator to check for possible obstacles on-screen without having to leave the machine. The color of the machine's icon will change to red when an obstacle comes underneath the machine to warn the operator.

Forward Mode

Obstacles to the front and their distance from the machine are detected by a millimeter-wave radar. A warning will be activated when another machine in front comes too close. This warning notifies the operator by a buzzer sounding as well as being shown on-screen. Warnings are set at two distance ranges depending on the position of the machine in relation to obstacles. The system adjusts the warning activation distance depending on the current gross laden weight of the vehicle. It detects the wheel rotation direction and enables or disables the warning accordingly, which is activated only during forward travel.

Hauling Capability

Refined engineering and advanced Hitachi AC Drive system technology have created hauling capability well recognized in the surface mining industry. The EH5000AC-3 continues to prove itself as an exceedingly capable and reliable solution to mine applications worldwide.

AC Drive Advantage

Hitachi AC drive technology provides superior truck performance with higher top speeds, better gradability and stronger electric braking. 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 tonne. Hitachi AC drive systems also power electric train locomotives worldwide.

Hitachi Drive Control System

New Hitachi drive control system for optimal operational stability and performance as follows. If the system senses slipping or locking of rear wheels when traveling on slippery or frozen roads, it adjusts the torques of the wheel motors accordingly, bringing the truck more stable traveling. If the system senses pitching when traveling on bumpy roads or stopping abruptly, it adjusts the torques of the wheel motors accordingly to reduce pitching of the truck, resulting in better operating comfort and fewer load spillage. If the system senses oversteer or understeer from the newly equipped sensors, it adjusts the torques of the wheel motors accordingly to control the side skidding. This brings the truck smoother movements and more stable traveling and steering.

AC Drive Control

Superior Electric Braking enables the driver to stop the truck using the electric brake pedal only with the exception of emergencies, because the AC drive control system applies the service brakes automatically just before the stopping, resulting in easy machine operation and longer time between service brake maintenance intervals. 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.

The AC Drive Wheel Motors

The Hitachi Dual Path Epicyclic Planetary design provides high efficiency and easy maintenance. Allowing the 1st (outer) planetary carrier to travel at wheel speed provides lower operating temperatures. Better component and lubricant life is the result of an inverter controlled lubricant circulation system that includes lubricant cooling and filtration.

Suspension

Front Suspension Independent trailing arms make up the front axle. NEOCON struts containing energy-absorbing gas and compressible NEOCON-E™ fluid are mounted between the trailing arms and frame. Inherent in the NEOCON strut design is a variable damping and rebound feature.

Rear Suspension

A frame structure, integral with axle housing, links the drive axle to the frame at a forward center pivot with pin and spherical bushing. A track rod provides lateral stability between the frame and drive axle. Heavy-duty rear-mounted NEOCON struts containing energy-absorbing gas and compressible NEOCON-E™ fluid suspend the drive axle from the frame. Integral variable damping and rebound feature included.

Perimeter visibility (standard)

The addition of mirrors and cameras to the base model make the truck compliant to the perimeter viewing requirement of standards ISO 5006 and ISO 14401.

The Fast Filling System

The fast filling system, provided standard on the left side of the radiator, allows direct access at ground level for fast feeding of coolant, grease, hydraulic oil and engine oil. (Couplers are optional).

Long Frame Life

A fabricated box section and rectangular frame rail construction provides superior resistance to bending and torsional loads. One-piece top and bottom flanges eliminate cross member tie-in joints and provide a larger exposed center area for access to major components.

Tough Body

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

Frame

Full fabricated box section main rails with section height tapered from rear to front. Narrow at the rear to support the loads and wider at the front to allow for engine accessibility. One-piece top and bottom flanges eliminate cross member tie-in joints and provide a large exposed center area for access to major components. Large radii minimize stress concentrations. Weld joints are oriented longitudinally to the principal stress for greater durability and more strength. New High Arch Design with bolted cross member design speeds assembling time and higher serviceability during engine overhaul.
