The invention discloses a frame, a chassis and engineering machinery and relates to the field of engineering machinery. The frame is used for optimizing the structure of the frame. The frame comprises an upper cover plate component, wherein the upper cover plate component comprises a front upper cover plate, a middle upper cover plate and a rear upper cover plate; the middle upper cover plate has an upper convex arc-shaped structure; the front upper cover plate and the rear upper cover plate are respectively arranged at the two ends of the middle upper cover plate. According to the technical scheme, a prior reaction principle is applied and all the upper cover plates are designed into raised structures in the form of hook surface, so that the rigidity of local box shape is increased, deflection is reduced, local stability of the cover plates are improved and the cover plates are prevented from being bent.
