Double element and pre-filtered Turbo with auto dust

evacuation.

q 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 355 l/min • Pilot pump

Gear pump – max flow: 22 l/min • Main relief valves

Boom/arm/bucket:

Normal mode: 320 kg/cm 2 (314 bar) Power mode: 350 kg/cm 2 (343 bar) Travel: 320 kg/cm 2 (314 bar) Rotation: 260 kg/cm 2 (255 bar)
