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.
