The invention relates to the field of tunneling construction of tunnel shield machines, and discloses a turnover bracket and a hoisting method of a shield main drive. The turnover bracket comprises alifting frame and a support frame which are separately connected to the two opposite sides of the shield main drive; the lifting frame is mainly used for connecting a lifting hook of a crane, and thesupport frame is mainly used for assisting in turnover in the lifting process, and preventing bumping during lifting; and the turnover bracket can be used for protecting the shield main drive in the whole lifting and shaft hoisting process. According to the hoisting method of the shield main drive, the shield main drive can be lifted easily, and the turnover and whole lifting process can be achieved by one crane only; and the lifting space is saved.
