The invention relates to the technical field of cranes, and particularly provides a frame and a crane. The frame comprises a cover plate, a base plate and a web plate, the base plate is arranged below the cover plate, the web plate is connected between the cover plate and the base plate so that the cover plate, the base plate and the web plate are encircled to form a box-shaped structure, the cover plate comprises a first protruding part, the first protruding part protrudes upwards, the first protruding part is suitable for being arranged below a large arm or a variable-amplitude oil cylinder of the crane, and/or the base plate comprises a second protruding part, the second protruding part protrudes downwards, and the second protruding part is suitable for being arranged above a non-driving axle of the crane. The crane comprises the frame. The sectional area of the frame is increased, and the bearing capacity of the frame can be effectively improved. Besides, the height of the whole crane is not influenced, and compared with a mode of increasing the thickness of the cover plate or the base plate, the weight of the frame is not greatly influenced.
