The invention belongs to the technical field of rotary excavating cranes, and particularly relates to a multipurpose rotary excavating crane. The multipurpose rotary excavating crane comprises a chassis, a U-shaped connecting frame, an auxiliary winch and a main winch are arranged on the chassis, the U-shaped connecting frame is hinged to a suspension arm mast basic section and a suspension arm mast variable-amplitude oil cylinder, the suspension arm mast variable-amplitude oil cylinder is hinged to the suspension arm mast basic section, the suspension arm mast basic section is connected witha suspension arm mast second section through a suspension arm mast telescopic oil cylinder, a suspension arm mast inner section is arranged in the suspension arm mast second section in a sliding mode,a slideway and a pressurizing oil cylinder are arranged on the suspension arm mast basic section, a power head is connected with the suspension arm mast basic section through the slideway, and a piston rod of the pressurizing oil cylinder is hinged with the power head. When used as pile work equipment, a steel wire rope on the main winch is connected with an elevator, and when used as a crawler-type crane, the steel wire rope is connected with a lifting hook. Two functions of a rotary drilling rig and a crane are integrated, the construction efficiency is improved, combined device number is reduced, the equipment switching time is shortened, and the construction cost is reduced.
