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.
• I-OHS (Integrated Optimum Hydraulic System)
LD:16 main pumps and 6 control valves and 2 set of flow-assisting
valves enable both independent and combined operations of all
functions.
BH:16 main pumps and 8 control valves.
• 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.
• Hydraulic drive cooling-fan system for radiator.
• Forced-lubrication and forced-cooling pump drive system.
