Hitachi Construction Machinery (Europe)/(HCME) has launched its new EH5000AC-3 rigid dump truck, the largest Hitachi dump truck featuring the advanced Hitachi AC drive system, which was developed using advanced propulsion technology of the type that also powers Japan’s bullet trains.
The new EH5000AC-3 features the third generation Hitachi Drive Control System, which 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 new model 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 has been designed with a Cummins QSKTTA60-CE diesel engine that meets EPA Tier 2 emission requirements, and the truck also features an advanced braking system, which provides precise braking and quick system responses. A new Hitachi system monitor provides display information and diagnostics of all onboard systems and controls.
“Since Hitachi began producing its own drive system four years ago with the launch of the EH3500ACII, it has resulted in the rapid development and enhancement of this technology,” says Greg Smith, HCME manager for heavy and mining equipment.
