A hydraulic safety circuit for use in earth-moving vehicles or agricultural vehicles or in general hydraulic machines. The hydraulic safety circuit includes a first hydraulic actuator, a pilot pump for supplying pilot operating fluid at a pilot pressure, and a signaling device controlled by the pilot fluid and operable to emit an alarm signal. The circuit further includes a balance valve subjected to pressure of the first hydraulic actuator and able to distribute the pilot operating fluid in a plurality of hydraulic activating signals; a hydraulic distributor able to assume a plurality of operating configurations and able to distribute the pilot operating fluid according to an assumed configuration; and a plurality of alarm valves controlled by the activating signals, at least one of which is arranged downstream of the hydraulic distributor, each alarm valve being able to provide the pilot fluid to the signaling device.
