Dumper frame and dumper

The utility model provides a dumper frame and a dumper. The dumper frame comprises an auxiliary frame and a compartment chassis hinged to the upper portion of the auxiliary frame. The auxiliary frame can support the compartment chassis. The auxiliary frame comprises two parallel auxiliary frame longitudinal beams and an auxiliary frame transverse beam welded between the auxiliary frame longitudinal beams. The compartment chassis comprises two parallel chassis longitudinal beams and a chassis transverse beam welded between the chassis longitudinal beams. The bottom face of each chassis longitudinal beam is provided with at least one longitudinal groove. The top of each auxiliary frame longitudinal beam is provided with at least one insertion portion. The insertion portions can be inserted into the longitudinal grooves when the compartment chassis is in the horizontal state so as to prevent the compartment chassis from swinging leftwards or rightwards. According to the dumper frame, due to the cooperation of the insertion portions of the auxiliary frame longitudinal beams and the longitudinal grooves in the compartment chassis, dislocation of the auxiliary frame and the compartment chassis longitudinal beams can be prevented, the whole structure is compact, the height of the center of gravity of the whole dumper can be lowered, and the safety of the dumper is improved.
