The invention relates to a crane transferring method which comprises the following steps: the vehicle body part of a crane is jacked until a guide rail wheel with a variable flange structure, for balancing a trolley, of the crane is completely separated from a track; subgrade boxes are paved to a target construction site; for each subgrade box, a cover plate of each subgrade box covers a groove, and therefore a rigid platform is formed; the flange structure of the guide rail wheel with the variable flange structure is retracted, and therefore the guide rail wheel with the variable flange structure can be adjusted into a structure without flange; the direction of the guide rail wheel with the variable flange structure is adjusted to be consistent with the transferring direction of the crane; the vehicle body part of the crane is dropped, and therefore the guide rail wheel with the variable flange structure makes contact with the subgrade boxes; the crane walks on the rigid platform in the transferring direction to the target construction site. The crane transferring method overcomes the defects of long dismounting cycle and serious mechanical wear of the traditional crane in the transferring process and effectively solves the problem of difficult crane transferring.
