The invention provides a safety height limiting device for a hoisting machinery. The safety height limiting device comprises a hoisting drum shaft, an outer shaft sleeve, an inner shaft sleeve, a shaft end transparent cover, a height gauge, a shaft end gland and a bearing, wherein the front end of the inner shaft sleeve is embedded into the shaft end of the hoisting drum shaft, the connecting endof the height gauge 5 is embedded into the inner shaft sleeve, the outer shaft sleeve is sleeved on the inner shaft sleeve 3 and exposed on the outer ring of the shaft end of the hoisting drum shaft,the inner ring of the bearing is fixed on the outer ring of the shaft end of the hoisting drum shaft, the shaft end transparent cover is connected with the bearing outer ring, the inner hole of the shaft end transparent cover passes through the outer diameter of the outer sleeve, and the shaft end gland is fixedly connected with the shaft end transparent cover to fix the outer shaft sleeve on theshaft end of the hoisting drum shaft. The number of turns of the height gauge is adjusted at the site according to the lifting height requirements, and the speed ratio and model selection of the height gauge are carried out according to the crane parameter requirements. According to the invention, the safety height limiting device has the following beneficial effect: the device has a compact structure, wide adjustment range and accurate data, convenient installation and low manufacturing cost.
