A method for controlling lifting of a hanging load using a lifting winch integrating a drum on which a lifting rope is wound coupled to the load, includes measuring a mass parameter and a lifting speed representative of a mass and of a displacement speed of the load and supervising an emergency stop which, once activated, shuts off the lifting winch. The method also includes, during an ascending of the load, comparing the lifting speed with a low threshold and a high threshold which vary according to the mass parameter, and monitoring lifting in an optimized mode in which the lifting speed when ascending is authorized below the high threshold and forbidden above the high threshold, and if the emergency stop is activated during an ascending and while the lifting speed is higher than the low threshold then an alarm is activated.
