STANDARD & OPTIONAL EQUIPMENT
���������� High power and torque engines with the right torque curve characteristics are perfectly matched to smooth-shifting, efficient transmissions in a light, yet strong chassis, providing class leading power and payload to weight ratios, to maximize cycle speed and efficiency. The AH400-D's higher standard specification includes new wet disc, full-hydraulic activated brakes which boost braking force and decrease stopping distances, while providing unaffected performance in deep mud applications. EVB(Engine Valve Brake) and exhaust brake as primary retarders are stronger and more efficient, and substantially contribute to strong downhill retardation.In addition, D-series has the transmission output retarder as main retarder.
����� � ��
Hitachi machines feature high power to weight ratios, and now combined with larger payloads, more stopping power and comfortable cabs, operators will be able to produce faster cycle times, delivering more material throughout the longest shifts.
������
Highly fuel-efficient, electronically managed diesel engines coupled to efficient planetary automatic transmissions in a light overall package deliver higher torque at lower revs where less fuel is burned. The transmission spends as much time as possible in lock-up mode to save fuel.
������� ����������
Six-wheel drive ADT's perform best when they are built light, with evenly laden axles, equal torque split to each axle, high suspension travel and good ground clearance and approach angles.
Stable PowerfulEconomical

������� The all-new ROPS and FOPS steel framed operator cabins, have fewer pillars for excellent all-round vision. Inside, the soft touch, wrap around dashboard gives an automotive feel, and all controls are clustered and within easy reach. A dedicated ADT instrument cluster provides all operational data, along with diagnostic displays and malfunction warnings. The latest full-hydraulic orbital steering system provides smooth, low effort, yet direct steering.
����� ��������� ������������� ��������It is Hitachi's mission to provide the market with simple to operate machines, as skilled plant operators are hard to come by. Starting with the fully automatic transmission with *touch pad shift control, automatic gear downshifts and retarder activation to the *abuse-proof CTD(Controlled Traction Diffs) differentials - operators are able to concentrate on the job at hand, while giving the owners peace of mind from possible costly machine damage.
�� ����������� ������� �������������Extended service intervals and the use of modern, low maintenance bearing materials, long life synthetic transmission and transfer case oils have reduced the D-Series maintenance requirements. The entire driveline, electric and hydraulic components as well as all electronics are fully accessible via easy to get to tilt bonnets and cabs, belly plates and hinged door panels.
