The invention provides a loading device for an overload shock of a gyro-stabilized platform. According to the invention, an output shaft of a servo motor is connected with a platform body, and a gyro is mounted on the platform body; an outer ring of an angular contact bearing is connected with a carrier, and an inner ring of the angular contact bearing is connected with the platform body; one side of a thrust bearing is connected with the outer ring of the angular contact bearing through a bearing support, the other side of the thrust bearing is contacted with a spring end face perpendicular to a spring axle center, and another spring end face perpendicular to the spring axle center is contacted with the surface of a thrust flat plate; and the angular contact bearing, the thrust bearing and the spring axle center are located on a same straight line. With the loading device provided by the invention, control performances of the gyro-stabilized platform in the state of an overload shock can be effectively improved, and loading of the overload shock of the gyro-stabilized platform can be realized.
