Therefore, it is important to design reasonable crane. This topic is related to the design on hoisting mechanism of 10t double-girder bridge crane with hook. The wire rope, pulley block and drum are calculated and designed based on the raw data of the hoisting mechanism, the model of coupling and brake are chosen by the requirements of hoisting mechanism, and the appropriate motor is chosen by the driving power; and the reasonable secondary reducer is calculated and designed by total velocity ratio. On the basis of accomplishing the design, the processing craft of some mechanism parts are established. The hoisting mechanism has stable performance. And it will have good prospect of development.
