Abstract: The design ideas and main features of two hoisting mechanism scheme of 650kN slewing crane in intake tower of Qingjiang Shuibuya hydroproject were introduced. The hoisting mechanism of main hook and auxiliary hook of slewing crane had been improved; the original two joint reels were replaced by one double joint reel. Then the operational synchronicity of slewing crane was increased, the mechanism and structure of slewing crane were simplified, and the antioverturning stability of the gantry crane was enhanced.

Key words: 650kN slewing crane, clean up grab, hoisting mechanism of slewing crane, both joint reel, double broken line groove
