Disclosed is an unmanned crane provided with an automatic hooking-unhooking device and an operating method thereof. The unmanned crane comprises a grid guide frame trolley, a ground assistance frame, and a ground load transporting device. The grid guide frame trolley can perform lateral displacement along a bridge. The rigid guide frame trolley is connected to a hoisting mechanism that makes a load have no horizontal displacement in the process of lifting and lowering the load. An automatic hooking-unhooking device is disposed at the bottom end of the hoisting mechanism. The ground assistance frame is rigidly connected to the ground. The automatic hooking-unhooking device comprises a guide wheel, a first guide rail matched with the guide wheel is rigidly connected to the bottom of the guide frame trolley, and the ground assistance frame is provided with a second guide rail matched with the guide wheel. The automatic hooking-unhooking device of the hoisting mechanism, a rigid frame of the trolley and the ground assistance frame working in conjunction with each other can achieve the functions of automatically loading and unloading a load in the unmanned crane, such that no horizontal displacement of a whole system is generated during the process of lifting and lowering a spreader, and thus high reliability and safety are provided.
