A method for monitoring operation of a winch having a motor driving a drum on which a cable is wound, the cable being able to be wound on several winding layers whose number varies depending on the winding and unwinding of the cable, the method implementing continuous monitoring of the number of winding layers of the cable on the drum while ensuring in real time at least the following steps: measuring a first parameter (P1) representative of a linear travel speed of the cable leaving the drum; measuring a second parameter (P2; P2′) representative of a rotation speed of the drum; and determining the number of winding layers of the cable depending on the first parameter and the second parameter. This method may find an advantageous application in the monitoring of winches of lifting device, and in particular cranes.
