The invention discloses a hoisting method for a prefabricated part. After the prefabricated part is solidified and formed, large-size hoisting equipment is used for hoisting the prefabricated part up from a die plate; and before the hoisting operation, a demolding process is carried out. According to the hoisting method for the prefabricated part, before large-size hoisting equipment is used for hoisting the prefabricated part up, the prefabricated part is hoisted up from the die plate by using a bracket and chain blocks so as to be demolded; the chain blocks are simultaneously tensioned according to the same frequency and the same amplitude; and the surface of the prefabricated part can be effectively prevented from being damaged.
