Hitachi launch EH5000AC-3 rigid dumptruck
Company introduces its largest rigid vehicle featuring advanced Hitachi AC Drive System
HITACHI Construction Machinery (Europe) NV (HCME) have announced the launch of their largest rigid dumptruck – the EH5000AC-3.
One of the most technologically advanced products of its kind, the dumptruck features the advanced Hitachi AC Drive System, which uses advanced propulsion technology to deliver new levels of efficiency and enhanced productivity. This technology, which also powers Japan’s bullet trains, is said to outperform previous and rival systems thanks to its simplicity, improved efficiency and greater reliability.
The new EH5000AC-3 also features the third-generation Hitachi Drive Control System. This incorporates such functionalities as slip control for traction (similar to active traction control) and slide control for grip (similar to an anti-lock brake system). The dumptruck also has a pitching prevention feature for a smoother ride and control of bouncing when stopping, and a Slip Angle Control function for stable cornering on slippery road conditions.
The EH5000AC-3 is powered by a Cummins QSKTTA60-CE diesel engine that generates 2,125kW (2,850hp) at 1,900 rev/min and meets EPA Tier 2 emission requirements. The truck also features an advanced braking system, which provides precise braking and quick system responses, while a new Hitachi system monitor provides display information and diagnostics of all onboard systems and controls.
Greg Smith, HCME manager for Heavy and Mining Equipment, said: ‘Since Hitachi began producing their own drive system four years ago with the launch of the EH3500ACII, it has resulted in the rapid development and enhancement of this technology. Hitachi is the only company in the industry that designs and manufactures all components of its drive control system.’
