Abstract: This method for protecting a lifting member against an overload, the lifting member comprising a lifting drum over which a cable is wound at the end of which a load is fixed, said lifting drum being mechanically connected to an electric motor capable of ensuring its rotation, the mechanical connection comprising a clutch or equivalent device, comprises at least two distinct operating thresholds:



a first threshold, the exceeding of which generates the freewheel operation of the lifting drum with respect to the kinematic chain coming from the electric motor;
a second threshold, of value greater than that corresponding to the nominal load of the lifting member, but of value less than that of the first threshold, generating the braking of the rotation of the lifting drum, and an attempt to progressively stop said rotation of the drum.

Abstract: This device for protecting a helicopter embarking a hoist provided with a hoisting cable against the consequences of an abrupt rupture of said cable, the hoist being provided with an outlet port for the cable, is formed by a shield positioned in the vicinity of the outlet port of the cable or deployable in the vicinity of the outlet port of the cable, said shield being oriented substantially perpendicularly with respect to the direction of said outlet port and extending over a distance of at least 20 centimeters with respect to said outlet port.
