HYDRAULIC SYSTEM

Hitachi's ETS (Electronic Total control System) can achieve maximum job efficiency by reducing fuel consumption and noise levels, while maximizing productivity through the optimization of engine-pump functions with excellent controllability increasing operator comfort.

• E-P Control (Computer-aided Engine-Pump Control system) Main pumps regulated by electric engine speed sensing control system.

• OHS (Optimum Hydraulic System)6 main pumps and 3 valves system enable both independent and combined operations of all functions.

• FPS (Fuel-saving Pump System)FPS minimizes energy loss with superior performance in fine control.

• Auto-idling system for saving fuel and reducing noise.• Hydraulic drive cooling-fan system for oil cooler.• Forced-lubrication and forced-cooling pump drive system.
