Hitachi AC drive technology provides superior truck performance with higher top speeds, better gradeability and stronger retardation. Hitachi inverter modules provide high rigid truck controlability 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 world wide. Water Cooling Pump Grid Motor Retarding Grid...

Superior Suspension The Hitachi trailing arm suspension system delivers excellent maneuverability, even at higher speeds. The trailing arm layout offers greater ease of servicing while improving truck performance compared to suspended king-pin designs. The pivot mounting of the trailing arm design allows only axial input to the strut and allows wheel movement to the vertical plane only. Features: • Lateral forces that act on the front wheels are minimized, resulting in reduced tire scuffing. • Dynamic friction (side-wall force) within the strut is low due to the features of the trailing arm...

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. Arch Design requires less...
