The invention discloses a servo operating device for a crane. The servo device comprises a shell body, a support, a swing frame, a first level rotary shaft, potentiometers, a second level rotary shaft and a handle. When the handle is controlled by a hand of a person to swing, the first level rotary shaft and the second level rotary shaft are driven to rotate at the same time and two sets of the potentiometers feed back two voltage signals according to the rotational directions and the rotational angles of the first level rotary shaft and the second level rotary shaft; a crane control system controls the crane to move transversely or longitudinally by using the two electrical signals which are fed back. The swing direction of the handle can control the moving direction of the crane, and the swing direction is the same as the moving direction. The size of the swing angle of the handle can control the moving speed in the corresponding direction, and the bigger the angle is, the higher the speed is. Besides, the lifting movement can be conveniently controlled by adding a lifting control button on the handle. According to the servo operating device for the crane, the operation and control over the crane are more simple and convenient to an operator of the crane and one hand is freed so as to do other auxiliary works. In addition, the function that the crane moves simultaneously with the hand can be achieved if the servo operating device for the crane is fixed below a travelling trolley of the crane through an adjustable support, namely when the hand holding the handle moves by a certain distance in a certain direction, and the crane can move by the same distance in the same direction synchronously, so that the hoisting and conveyance of goods by the crane are more convenient and accurate.
