Hydraulic circuit for working machines comprising a power unit (P) for pressurizing a hydraulic fluid, a unit of distribution (D) comprising a plurality of proportional valves downstream of the power unit (P), a control unit (C) connected to the proportional distribution unit (C), a plurality of groups of hydraulic actuators (GA, GT, GS) that can be connected to the power unit (P) by the proportional distribution unit (D), and an operations control panel (CO) connected to the control unit(C). The hydraulic circuit comprises a flow diverter (DF) placed between the distribution unit (D) and the groups of hydraulic actuators (GA, GT, GS), so that the latter are selectively connectable to the distribution unit (D) by means of the diverter (DF). The flow diverter (DF) is controlled manually or by a program by means of the control unit (C). The number of proportional valves of the distribution unit (D) is equal to the maximum number of actuators that can be simultaneously activated. A group of hydraulic actuators (GS) is destined to execute of a phase of stabilization of the machine by activating corresponding stabilizers (4). |
