The invention discloses a height limit detecting structure. The height limit detecting structure comprises a differential gear box and a cam limit structure, wherein the first input shaft of the differential gear box is connected with a first hoisting winding drum, the second input shaft of the differential gear box is connected with a second hoisting winding drum, the turn rotation quantity of the first input shaft and the second input shaft is positive, and the counterturn rotation quantity of the first input shaft and the second input shaft is negative; the cam limit structure is connected with the output shaft of the differential gear box; when a grab bucket ascends or descends, the absolute difference of the rotation quantity sum of the first input shaft and the second input shaft is larger than zero, the output shaft rotates under the action of the first input shaft and the second input shaft, and the cam limit structure transmits a detecting signal when the grab bucket ascends to a preset position; when the grab bucket does not ascend or descend, the absolute difference of the rotation quantity sum of the first input shaft and the second input shaft is equal to zero, the output shaft does not rotate, and the cam limit structure does not detect.
