1. A hybrid mobile operating machine comprising:
a motor vehicle driven by an internal combustion engine,
an articulated arm associated with a concrete delivery pipe,
a pumping unit suitable to pump concrete into said pipe,
a stabilization unit to stabilize said operating machine during the pumping and delivery of said concrete and primary services,
wherein said internal combustion engine is suitable to power at least a first power take-off and a second power take-off which can be activated selectively with respect to each other,
wherein to said first power take-off there is operatively connected a first drive unit comprising at least an electric accumulator, a first electric motor and a first hydraulic pump to selectively drive at least said stabilization unit, said articulated arm and said primary services, and
wherein to said second power take-off there is operatively connected a second drive unit comprising at least a second electric motor and a second hydraulic pump to drive at least said pumping unit, and
wherein said first drive unit and said second drive unit are operatively associated with each other and independent from each other, so that when one of either said first drive unit or said second drive unit is activated, it is possible to keep the other deactivated.
