The invention discloses a double-joint support convenient to assemble and disassemble for a crane. The double-joint support comprises a base plate, a main base and lateral support beam, wherein the main base is welded and fixed at the central position of the base plate and perpendicular to the base plate; the lateral support beam is welded and fixed on the side wall of the main base; inclined faces are symmetrically arranged on two sides of the lateral support beam; a rounded angle is invertedly arranged at the joint of two inclined faces; a first axle hole is formed in the center of the main base; a pin hole is formed in a position corresponding to the first axle hole in the main base; an axle wire of the pin hole is perpendicular to an axle wire of the first axle hole; a second pin hole is arranged in a position, close to the rounded angle, of the top end of the lateral support beam; and an axle wire of the second axle hole is parallel to the axle wire of the first shaft hole. According to the double-joint support, double joint connection can be achieved, and the requirement for strength under the condition of heavy load can be guaranteed; a form of welding is adopted, so that the whole processing cost is low, and the double-joint support can be widely used; and at the same time, the double-joint support can be fixed through the base plate and is convenient to assemble and disassemble.
