A method and arrangement for operating a ship ramp driven by an electric motor between an upper end position and a lower end position, the arrangement comprising means (40) for reducing the maximum torque of the at least one electric motor (30) when the ramp (10) is in proximity to an end position of the ramp, means (40) for determining the position of the ramp (10) on the basis of the number of rotations performed by the at least one electric motor (30), or a quantity indicative thereof, or on the basis of the elapsed time and the velocity of the ramp, and means (40) for allowing the reduction of the maximum torque of the at least one electric motor (30) only when the determined position of the ramp (10) is within a zone defined by predetermined limits.
