The invention discloses an adjustable building crane, and relates to the technical field of building cranes. The adjustable building crane comprises a crane frame and a control chamber at the top of the crane frame, wherein one side of the top of the crane frame is fixedly connected with a crane jib; a lifting hook part is arranged at the bottom end of the crane jib; the lifting hook part comprises a transmission inner frame; the two sides of the interior of the transmission inner frame are symmetrically and rotationally connected with limiting conduction mechanisms; air inducing adjusting mechanisms are arranged in the middles of the front end and the rear end of the transmission inner frame; a stable hanging mechanism is fixedly connected to the middle of the bottom end of the exterior of the transmission inner frame; and steel cables are arranged on the surfaces of the bottoms of the limiting conduction mechanisms in a rolling mode. According to the adjustable building crane, the steel cables are prevented from being subjected to wind vibration in the transmission process, the stability of the connection of the steel cables in the lifting hook part is guaranteed, and the flexible adjustability of the crane is realized.
