environment
The air-conditioning and heating systems are integrated for optimal climate control. An automatically controlled fan supplies the pressurised and filtered cab air, which is distributed throughout the cab from multiple vents. The heated air suspension, adjustable operator’s seat includes a seat belt. The operator can adjust the ergonomic seat and joystick console separately according to his preferences.

A-weighted sound power level, LwAd (2000 / 14 / EC)
Declared: 103 dB(A)
Measured: 101 dB(A)
hydraulic system
The e-EPOSTM (Electronic Power Optimising System) is the brain of the excavator – minimising fuel consumption and enabling the efficiency of the hydraulic system to be optimised for all working conditions.
To harmonise the operation of the engine and the hydraulics, the e-EPOS is connected to the engine’s electronic control unit (ECU) via a data transfer link.
- The hydraulic system enables independent or combined operations
- 2 travel speeds offer either increased torque or high speed
- Cross-sensing pump system for fuel savings
- Auto-deceleration system
- 4 operating modes, 4 power modes
- Flow and pressure control of auxiliary hydraulic circuits from control panel
- Computer-aided pump flow control

swing mechamism
The swing mechanism uses an axial piston motor, driving a 2-stage planetary reduction gear bathed in oil for maximum torque.
- Swing bearing: single-row, shear type ball bearing with induction hardened internal gear
- Internal gear and pinion immersed in lubricant
Maximum swing speed
11.3 rpm
Maximum swing torque
