Hydraulic System    
The power train consists of two main drives. Diesel engines or electric motors can be supplied. Each connected to a gearbox and 3 identical main pumps which draw hydraulic oil from an unpressurized hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency.    
The four-circuit system features a load-limiting governor with oil delivery summation to the working circuits and incorporates pressure cut-off control. Hydropilot prioritizes hydraulic flow giving smooth hydraulic response, simple hydraulic system layout, and a reduced number of components. Filtration is at the oil intake to pumps, valve blocks, heat exchangers and the oil tank.

Vehicle Monitoring System    
The Electronic Control System (ECS) digital diagnostic system, mounted in the operator’s console, provides a text display of realtime and stored information about the operating systems of the machine. Non-serious and critical faults are immediately announced, and for major malfunctions the engines are also shut down. The integrated digital storage provides full event history, which can be downloaded with a laptop computer. The ability to electronically record service events provides precise service information to assist in reducing downtime.    
The large welded steel cab is mounted with 18 viscous damping pads and sound insulated.    
It is equipped with automatic climate control and is pressurized. The operator’s seat is fully adjustable, air suspended, electrically heated and has a lap seat belt. Trainer’s seat included.    
Low effort joystick controls are electric over hydraulic and foot controls are for front shovel clam, crawler and swing brake.
