Supporting method of crane assembly

The invention provides a supporting method for a crane assembly. The supporting method comprises the specific steps that S1, the crane assembly is installed on a supporting column; s2, the gravity of the crane assembly is conducted to a supporting column; (1) the gravity of the crane assembly is transmitted to the supporting column; the supporting column transmits the force to the base; (2) in the process of transferring the crane assembly, the road surface is uneven; the supporting columns can be subjected to a certain inclination force; (3) partial force is applied to the inclined strut, and the force applied to the inclined strut is transmitted to the base at the same time; s3, the supporting rib plates bear a part of force transmitted from the supporting columns; s4, part of force is transmitted to the supporting bottom plate through the supporting rib plate and borne by the supporting bottom plate; s5, a part of force transmitted to the base by the inclined strut is borne by the supporting top plate; s6,
