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.

Automatic Centralized Lubrication   
Two hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. Activity and malfunction events are linked to the ECS.

The central lube grease system is supplied from a refillable 300 liter / 80 gal. container. A second, identical system supplies open gear lubricant to the swing ring teeth through a lube pinion. Replenishment of the containers is through the service center.

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.

Full instrumentation and Electronic Control System (ECS) are provided. Space in the console is provided for an additional monitor. AM/FM radio is included. The dual windshield wipers have two-speed and intermittent operation (water reservoir 7 liters 1.8 gal.). Amenities include a wash basin with running water (water reservoir 50 liters 13 gal.), refrigerator, and storage cabinets. Powered mirrors are adjustable from inside the cab. 
There are left and right-hand sliding windows. All windows are tinted parsol green. External metal louvers are provided on the cab side windows.     
Cab engineering standards are:     
• ISO 3449 Falling Objects Protection Structure (FOPS) Level 2     
• ISO 6396 Noise in operator´s cab is 76dB(A)     
• Air conditioner  34,120 Btu/hr  10 kW 
• Heater/Defroster (Diesel version)  34,120 Btu/hr  10 kW 
• Heater/Defroster (Electric version)  40,940 Btu/hr  12 kW
