A method and arrangement are provided for operating a ship ramp driven by an electric motor between an upper end position and a lower end position. The arrangement includes means for reducing the maximum torque of the at least one electric motor when the ramp is in proximity to an end position of the ramp, and means for determining the position of the ramp on the basis of at least one of the number of rotations performed by the at least one electric motor, a quantity indicative of the number of rotations, and an elapsed time in accordance with the velocity of the ramp. The arrangement also includes means for allowing the reduction of the maximum torque of the at least one electric motor only when the determined position of the ramp is within a zone defined by predetermined limits.
