Crane main beam structure configuration using corrugated steel plate composite sandwich as web plate

The invention relates to a crane main beam structure configuration using a corrugated steel plate composite sandwich as a web plate, and belongs to the technical field of crane industry, wherein the crane using the main beam structure configuration can meet the lifting uses of various corresponding cranes. According to the embodiment, the crane main beam web plate meeting the existing national standard is subjected to improved design so as to increase the carrying capacity, wherein the corrugated steel plate is used as the middle layer, and is clamped by the two web plates left and right, andthe three plates are welded and connected integrally so as to be used as the one web plate, such that the corrugated steel plate composite sandwich is used as the web plate. According to the present invention, the crane main beam structure configuration using the corrugated steel plate composite sandwich as the web plate is provided; and in order to reduce the weight, the height is reduced to 2/3-4/3 of the height of the
