The invention relates to a bladed disk part hoist. The hoist comprises a hoisting lug, a hoisting rod, an upper supporting plate, a supporting jaw assembly, a supporting limiting device and a limitingdevice. The hoisting lug is connected to a crane and used for force bearing and transferring. The hoisting lug is connected with the hoisting rod. The supporting limiting device and the limiting device are arranged at the two ends of the hoisting rod correspondingly, and the opening angle of the supporting jaw assembly is controlled and fixed. One end of the supporting jaw assembly is connected to the upper supporting plate and arranged on the hoisting rod in a sleeving mode and can slide up and down, and the other end of the supporting jaw assembly is a free end. On the premise that parts are not damaged, traditional hoists using bolts holes are replaced by the hoist using disk centers. By using the bladed disk part hoist, the engine assembling efficiency is greatly improved.
