Certain job conditions may require higher TKPH (TMPH) in order to maintain maximum production. Hitachi recommends evaluating the job conditions and consulting the tire manufacturer to make proper tire selection.

Twenty-four volt system. 260 ampere engine driven alternator. Six G31, 12 volt, heavy duty maintenance free batteries connected in series/parallel.

Body capacity and payload subject to change based on customer specific material density and application.

Closed-center, full time hydrostatic power steering system using two double-acting cylinders and a variable displacement piston pump. Hitachi accumulators provide supplementary steering in accordance with ISO 5010 (SAE J1511), supplying a constant steering rate under all conditions. A tilt/telescopic steering wheel with 35 degrees of tilt and 57 mm telescopic travel is standard.

A dual tank assembly prevents cross contamination between the steering/brake apply system and the hoist/brake cooling system. Two (2) Hitachi three-stage, double-acting cylinders, with improved control in extension, containing dual rod seals and urethane energized scrapers, inverted and outboard mounted. The cylinders are connected to a tandem gear pump through a four position electronically piloted hoist control valve. An electric controller is mounted to operator's seat.

Brake systems complies with ISO 3450 (SAE J1473).

The all-hydraulic actuated braking system provides precise braking control and quick system response. The system is pressure proportioned, front to rear, for improved control on slippery roads.

Dual independent hydraulic circuits within the service brake system provide fully modulated reserve braking capability. Both front and rear brakes are automatically applied when loss of supply pressure is detected.

Superior retardation to zero speed on grades is achieved through AC wheel motors in conjunction with the Hitachi silent resistor grid packages.

Through activation of a switch by the operator, a solenoid is energized, sending full brake pressure to apply the rear wet disc brakes. For use during the load and dump cycles.

ROPS and FOPS comply with ISO3471, SAE J1040-May 94 and ISO3449. A three-point rubber iso-mount arrangement to the high-arch cross member minimizes vibration transfer to the operator compartment.

A new color LCD has been engineered onto the dashboard of the EH5000ACII. All lights, gauges and indicators are provided in one location, bringing ease of operation to the operator.

Included as standard visibility equipment, an analog monitor has been mounted to the upper console to display live camera information of the rear, front bumper, and right front tire area.

The enlarged cab adequately fits a full size trainer's seat and provides more overall comfort. Ample visibility is provided by large glass sections in doors and windows. An ergonomic shift lever that is positioned for ease of operation also increases operator comfort. Heating capability of 40 000 BTU/hr, and cooling capability of 30 500 BTU/hr to provide comfort in a wide range of ambients. Improved cab air flow has increased pressurization. The cab air filter element is easily accessible from behind the front cab cover. The heating/air conditioning system provides an LCD display with push button control. A new parking brake alarm will sound if the parking brake switch is not in the applied position while the engine is running and the operator is not sitting in the drivers seat. Optional electric windows are available for both cab doors. The window control is available to the operator and rider as the switches are mounted to the center console. Cab interior sound pressure level measured according to ISO6394:1998 is 79.3 dB(A).

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

An "A" frame structure, integral with axle housing, links the drive axle to the frame at a point forward of center using a 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 TM fluid suspend the drive axle from the frame. Integral variable damping and rebound feature included.

Full fabricated box section main rails with section height tapered from rear to front. Wider at the rear to support the loads and narrower at the front to allow for engine accessibility. One piece top and bottom flanges that eliminate cross member tie in joints and provide a large exposed center area for access to major components. Large radii minimize stress concentrations. Welded joints are oriented longitudinally to the principal flow of stress for greater durability and more strength.

An extended canopy protects service deck area. High tensile strength 400 BHN abrasion resistant alloy steel is used in thicknesses of:

High strength 690 N/mm² (100 000 psi) alloy steel is also used for the canopy side members and floor stiffeners. The body is rubber cushioned on the frame.
