The invention relates to the technical field of hoisting equipment, in particular to a combined type cantilever crane which comprises a basal body cantilever crane, an expanding cantilever crane and a cantilever crane connecting device, wherein the expanding cantilever crane is detachably connected onto at least one side face of the basal body cantilever crane through the cantilever crane connecting device. According to the invention, an integrated welding cantilever crane is modified into the detachable combined type cantilever crane, so that the design of the cantilever crane is free from limitation of transportation clearance, shipping weight and the like, and the bearing capacity of the cantilever crane is improved by times to meet the requirement for the bearing capacity of the cantilever crane from ultra-large type hoisting equipment.
