The invention discloses a split type hoisting method for a 5MW land type wind generating set. According to the method, a cabin is hoisted in a split mode, and split into a cabin body, a generator, a maintenance crane and a top housing according to the weight and the boundary dimension of all parts of the cabin and the hoisting capacity of a main hoisting machine; after the cabin is split, software is utilized for analyzing and recalculating the gravity center position to adjust the design of a hoisting sling, and therefore the level and the safety of cabin hoisting are ensured. The main hoisting machine is utilized for sequentially installing the cabin body and the generator in place and sequentially installing the maintenance crane and the top housing in place. According to a general scheme, a 1600t crawler crane is needed when a whole hoisting scheme is adopted for a 5MW fan, while by means of the implementation of the method, the construction requirement can be met by adopting a 1000t crawler crane, and therefore the construction cost is effectively saved.
