Hydraulic system

The heart of the system is the e-EPOS (Electronic Power Optimizing
System). It allows the efficiency of the system to be optimized for
all working conditions and minimizes fuel consumption.
The new e-EPOS is connected to the engine electronic control via a data
transfer link to harmonize the operation of the engine and hydraulics.
• The hydraulic system enables independent or combined operations.
• Two travel speeds offer either increased torque or high speed
tracking.
• Cross-sensing pump system for fuel savings.
• Auto deceleration system.
• Two operating modes, two power modes.
• Button control of flow in auxiliary equipment circuits.
• Computer-aided pump power control.
• Main pumps
2 variable displacement axial piston pumps
Max flow: 2 x 247 l/min
• Pilot pump
Gear pump – max flow: 28,5 l/min
• Main relief valves
