Abstract
A mobile operating machine comprising a motor vehicle moved by an endothermic engine, an articulated arm, a pumping unit and a stabilizing unit wherein the endothermic engine is provided with at least two power take-offs. The mobile operating machine also comprises a hydraulic pump and an electric motor operatively connected to the endothermic engine, to the hydraulic pump and to an electric accumulator.
Claims10
A mobile operating machine comprising a motor vehicle moved by an endothermic engine, an articulated arm associated with a concrete delivery pipe, a pumping unit suitable to pump concrete into said pipe and a stabilizing unit for stabilizing said operating machine during the pumping and delivery of said concrete, wherein said endothermic engine is provided with at least a first power take-off and a second power take-off, distinct from the first power take-off, which can be activated selectively with respect to each other, wherein at least one hydraulic pump which drives said articulated arm and said stabilizing unit, an electric motor and an electric accumulator are connected to said first power take-off by means of a first drive axis (A1), and at least said pumping unit is connected to said second power take-off by means of a second drive axis (A2), distinct from said first drive axis (A1), and wherein along said first power take-off there is a disengagement device which can be selectively activated to alternatively determine the drive of said hydraulic pump by means of said endothermic engine, or by means of said electric motor.
