Method for limiting the maximum power required by the hydraulic system of an earth-moving machine, controlled by a sectional flow-sharing having multiple sections (A, B, C), each section comprising a local compensator (1) and a spool (2), at least one section (A o B) or both (A and B) of which requiring the maximum flow and at least one additional section (C) intended to actuate a high pressure use. It is provided for bypassing the local compensators (1) and the section(s) (A, B) that require the maximum flow in the moment in which it/they is/are actuated and concurrently completely relative to the third section (C) at high pressure, imparting a delivery pressure lower than that required by the section (C) and calculated so that the power required is less than or equal to the power that can be delivered by the motor M or less than the power at which the torque limiter intervenes, with the effect that the flow does not undergo reductions. |
