The invention discloses a platform for a ship crane. The platform comprises a platform device and a servo driving system, wherein the platform device comprises a fixing bracket, a plurality of rollers, a plurality of ropes and a bearing platform, the fixing bracket is fixedly arranged on the ship crane, the plurality of rollers are uniformly distributed on the profile of the fixing bracket, a plurality of hinges are fixedly arranged on the profile of the bearing platform, one end of each rope is around the rollers to be movably connected with the fixing bracket, and the other end of each rope is fixed on the corresponding hinges on the bearing platform; the servo driving system comprises a sensor, a control system, servo motor controllers and a plurality of servo motors, the sensor is fixedly arranged on the bearing platform, and the servo motor controllers are respectively used for controlling the servo motors. The platform has the advantages of high rigidity, high positioning accuracy, larger translational motion working space and faster moving speed, besides, impacts from the external force can be quickly responded. Therefore, the stability is kept when the bearing platform of the ship crane moves.
