The power train consists of two main drives. Diesel engines or electric motors can be supplied. Each motor is connected to a gearbox and three (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.

The high capacity engine radiators are cooled by hydraulically driven fans for superior cooling efficiency and require little maintenance. The hydraulic system includes two large swing-out vertical air-to-oil hydraulic coolers with temperature-regulated hydraulically driven fans.

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 litre 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 Wiggins service arm.

Two (2) heated rear view mirrors are externally fitted. External metal sun blinds. There are left and right hand sliding windows. All windows are tinted parsol green.

The ECS electronic health monitoring system, mounted in the operator´s console, provides a text display of real time and stored information about the status of the operating machine. Non serious and critical faults are immediately announced, and for major malfunctions the engines are also shut down. The intergrated 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.
