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 minimises fuel consumption.
The 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
- Cross-sensing pump system for fuel savings
- Auto deceleration system
- Two operating modes, two power modes
- Button control of flow in auxiliary equipment circuits
Main pumps
2 variable displacement axial piston pumps
Maximum flow: 2 x 220.21 l/min
Pilot pump
Gear pump – maximum flow: 26.1 l /min
Maximum system pressure
Boom / Arm / Bucket
- Normal mode: 350kgf/cm2
- Power mode: 370kgf/cm2
Travel – 330 kgf/cm2
Swing – 300 kgf/cm2
hydraulic cylinders
The piston rods and cylinder bodies are made of high-strength steel. A shock absorbing mechanism is fitted in at cylinders to ensure shock-free operation and extend piston life.

undercarriage
Chassis are of very robust construction; all welded structures are designed to limit stresses. High-quality material used for durability. Lateral chassis welded and rigidly attached to the undercarriage. Track rollers lubricated for life, idlers and sprockets fitted with floating seals. Tracks shoes made of induction-hardened alloy with triple grouser. Heat-treated connecting pins. Hydraulic track adjuster with shock-absorbing tension mechanism.
