BRAKE SYSTEM

Brake systems complies with ISO 3450 (SAE J1473).

Service

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

Front Axle - Dry Disc

Disc Diameter Each (2 discs/axle, 3 calipers/disc) 121.7 cm

Rear Axle - Dry Disc

Disc Diameter Each (2 discs/axle, 3 calipers/disc) 109 cm

Secondary

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

Parking

Two spring on, hydraulic off armature disc brake heads provide effective parking. The braking system complies with ISO 3450 (SAE J1473).

Retarder

Superior retardation to zero speed on grades is achieved through AC wheel motors in conjunction with four Hitachi resistor grid packages. Service brake blending occurs at speeds below 0.5 km/h.

Maximum dynamic retarding

Standard 2 800 kW

Load/Dump Brake Apply

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

HI-TECH ROPS/FOPS CAB

New HI-TECH ROPS/FOPS Cab

ROPS complies with ISO3471 and SAE J1040-May 94, FOPS complies with ISO3449. A three-point rubber ISO-mount arrangement minimizes vibration to the operator compartment.

Comfort and Ease of Operation

New wrap-around style dashboard means controls are within easy reach and visual contact. A full complement of easy-to-read automobile type color LCD monitor and warning system, a spacious environment, six-way adjustable operator's air seat, tilt/telescopic steering wheel, filtered adjustable air vents, all contribute to operator safety and comfort.

Monitoring System

A new Hitachi system monitor and diagnoses all onboard controls including the Hitachi drive system and engine. Data links offer complete integration, while a single color Liquid Crystal Display (LCD) clearly details machine functions. Downtime is minimized with faster and more reliable troubleshooting and analysis. A new Hitachi load monitoring 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 and cycle count can all be measured and recorded to further improvement of job productivity. The Hitachi load monitoring system is fully integrated with the Hitachi vehicle monitoring system and display interface, avoiding potential failure or error common in aftermarket systems.

Excellent Serviceability

A removable front cover of the cab allows easy access to the service brake valve and heater connections. A removable cover located behind the seat provides easy access to the electric components, Hitachi controller, and all electrical junction points.

SUSPENSION

Front Suspension

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 features are included.

Rear Suspension

"A" frame structure, integral with axle housing, links the drive axle to frame at a forward center point with a pin and spherical bushing. A track rod provides lateral stability between the frame and drive axle. Heavyduty rear-mounted NEOCON struts containing energy-absorbing gas and compressible NEOCON-E (TM) fluid suspend the drive axle from the frame. An integral rebound feature is included.

FRAME

Full fabricated box section main rails with section height tapered from rear to front. Narrow at the rear to support the load and wider at the front allowing truck stability and excellent engine access for servicing. 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 at frame junctions are blended and ground to minimize stress concentrations. Weld joints are oriented longitudinally to the principal flow of stress for greater durability and more strength.

BODY

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

Floor 19 mm
Front 10 mm
Sides 10 mm
Canopy 6 mm
Corners 12 mm

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.
