Abstract: Hydraulic control circuit for working members of earth-moving machines including linear and rotary hydraulic actuators associated with respective hydraulic distributors for the operation of respective working members. The rotary hydraulic actuators with their distributors are grouped in a circuit separate from the linear hydraulic actuators and are provided with braking valve means constituted by a single counterbalance valve connected in a common discharge line, the opening of which is controlled by a pilot pressure signal corresponding to the lowest supply pressure for the rotary actuators.
