hydraulic system
The heart of the system is the e-EPOSTM (Electronic Power Optimising System). It allows the efficiency of the system to be optimised 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 harmonise 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
Maximum flow: 2 x 114 l/min
