Thus, the hoisting device of the present application can simultaneously hoist the tower drum and the impeller, i.e. after the tower drum is hoisted, the posture can be adjusted for hoisting the impeller. Compared with the prior art, the phenomenon of replacing different hoisting tools when hoisting different objects (tower drum and impeller) can be reduced.
