Abstract
A hybrid mobile operating machine comprising a motor vehicle driven by an internal combustion engine, an articulated arm associated with a pipe, a pumping unit and a stabilization unit, primary services and auxiliary services, wherein the internal combustion engine is suitable to power at least a first and a second power take-off. The mobile operating machine is provided with both a first drive unit which comprises at least one electric accumulator, a first electric motor and a first hydraulic pump, and a second drive unit which comprises at least one second electric motor and a second hydraulic pump.
Claims10
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.
A functioning method of a hybrid mobile operating machine comprising a motor vehicle, driven by an internal combustion engine, on which there are mounted at least a stabilization unit, an articulated arm, a pumping unit and primary services, wherein the functioning method provides one or more functioning steps of a first drive unit that is operatively connected to a first power take-off driven by said internal combustion engine, in which said stabilization unit, said articulated arm and said primary services are driven by a first hydraulic pump by means of a first electric motor powered by an electric accumulator of said first drive unit, and one or more functioning steps of a second drive unit that is operatively connected to a second power take-off driven by said internal combustion engine, in which said pumping unit is driven by a second hydraulic pump by means of a second electric motor of said second drive unit, and herein said first drive unit and said second drive unit are driven independently of 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.
