Closed-center, full-time hydrostatic power steering system using two double-acting cylinders, pressure limit compensated piston pump, and a brake actuation/steering system reservoir. An accumulator provides supplementary steering in accordance with SAE J1511/ISO 5010.
Tilt/telescopic steering wheel with 35o of tilt and 57.15 mm (2.25") telescopic travel is standard.

Two (2) Hitachi three-stage, double-acting cylinders with cushioning in retraction, containing dual rod seals and rubber energized scrapers, inverted and outboard mounted. Separate reservoir and tandem gear pump connects with a four-position electric pilot controlled hoist valve. Electronic controller is mounted to operator's seat.

Brake systems meet or surpass SAE J1473/ISO 3450.

All-hydraulic actuated braking system provides precise braking control and quick system response. The system is pressure proportioned, front to rear, for improved slippery road control. Three calipers per front disc, one caliper per rear disc are utilized. The main valves are conveniently located on the firewall. This placement enhances service-ability as all pressure checks and system troubleshooting can be made at a central location. A primary accumulator stores oil under sufficient pressure to ensure 100% braking capacity is always available.

Two independent hydraulic circuits within the service brake system provide fully modulated reserve braking capability. The system is automatically applied when loss of pressure is detected.

Spring-on, hydraulic-off park brake heads provide parking capability.
The braking system complies with SAE J1473/ISO 3450.

Retardation on grades is achieved through D.C. wheel motors in conjunction with the General Electric resistor grid package located on the cab deck. Cooling for the grid package is achieved with forced air flow provided by dual blowers driven by a single electric motor.
Three-step extended range retardation package is standard.

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.

Command Cab III integral ROPS (Rollover Protective Structure) is standard in accordance with SAE J1040/ISO 3471.
Double wall construction of 11 gauge inner and outer steel panels produces a more structurally sound cab. Foam rubber lining material along with foam rubberbacked carpeting and multiple layered floor mat act to absorb sound and control interior temperature.
A properly maintained cab from Hitachi, tested with doors and windows closed per work cycle procedures in SAE J1166, results in an operator sound exposure Leq (Equivalent Sound Level) of 81 dB(A). A three-point rubber iso-mount arrangement to the deck surface minimizes vibration to the operator compartment.

CONTRONIC II monitors and diagnoses all onboard systems including Siemens drive system and engine. Data links offer complete integration, while a single multi-language Liquid Crystal Display (LCD) clearly details machine functions. Downtime is minimized with faster and more reliable troubleshooting and analysis.
HAULTRONIC II load weighing system offers benefits such as better equipment utilization on the jobsite, accurate unit and fleet production results, and benchmark unit statistics against fleet results.
Cycle time, distance, cycle count can all be measured and recorded to further and improve job productivity. HAULTRONIC II is fully integrated with CONTRONIC II vehicle monitoring system and display interface, avoiding potential failure or error common in aftermarket systems.

A removable front closure allows easy access to the service brake valve and heater connections. The upper dash utilizes four (4) removable panels that house gauges and customer options, each individually accessible. A removable closure located behind the seat provides easy access to the shifting control, CONTRONIC II, and all electrical junction points.

A wrap-around style dashboard positions controls within easy reach and visual contact. A full complement of easy-to-read gauges, CONTRONIC II monitoring and warning system, a spacious environment, six-way adjustable air seat, tilt/telescopic steering wheel, filtered ventilation, door locks, and a full size trainer seat, all contribute to operator safety and comfort.

Independent trailing arm for each front wheel. NEOCON struts containing energy-absorbing gas and compressible NEOCON-E (TM) fluid are mounted between the trailing arms and frame. Variable damping and rebound feature included.

"A" frame structure, integral with axle housing, links drive axle to frame at forward center point 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 rebound feature included.

The Hitachi frame and suspension are designed to work in unison to provide maximum structural integrity and operator comfort. The fabricated rectangular frame rail construction provides superior resistance to bending and torsional loads while eliminating unnecessary weight. The unique trailing arm front suspension absorbs haul road input, minimizing suspension-induced frame twisting while providing independent tire action. NEOCON ride struts are mounted with spherical bushings, eliminating extreme sidewall forces by insuring a purely axial input to the ride strut.
The wide track stance of the suspension system and the long wheel base assure a more stable, comfortable ride.

The unique Hitachi NEOCON struts both front and rear combine the energy absorption characteristics of two different compressible media: NEOCON-E liquid and helium gas. They provide nearly twice the energy absorption as Nitrogen over Oil struts. The result is more comfort for the operator, maximum protection for the hauler frame, and excellent stability and control. NEOCON-E has also been approved by the US EPA and does not violate codes defined by TSCA Section 5.

The NEOCON strut outperforms competitive strut designs by improving isolation, stability, and control. Improved isolation means reduced impact loading on structural members of the machine and greater operator comfort, resulting in longer equipment life and productivity. Improved stability means more consistent dynamic response of the machine to fluctuating load energy, resulting in predictable machine performance. Improved control also means better machine maneuverability.

The box section main frame rails are bridged by three crossmembers, front bumper and front suspension tube. The rails are constant taper, constructed of 690 N/mm² (100 000 psi) yield strength steel. Two rear crossmembers have integral suspension and drive axle mountings.
Crossmember to frame rail junctions employ large radii transitions to minimize stress concentrations.

The body has a flat floor, sloped tailchute, and is continuously exhaust-heated. Extended canopy protects service deck area.
High yield strength, 690 N/mm² (100 000 psi) alloy steel is used in the following thicknesses:

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.

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