The invention provides a main-auxiliary integrated frame of a heavy dumper. The main-auxiliary integrated frame comprises a main frame body and an auxiliary frame body. Integration reinforcing plates are correspondingly arranged on the outer sides of two longitudinal beams of the main frame body and extend from the tail of the main frame body to the portions, where front leaf springs and back lifting lugs are installed, of the main frame body, are of through type structures and are fixedly connected to the longitudinal beams of the main frame body through bolts or rivets. A notch structure is formed between the two integration reinforcing plates. The auxiliary frame body is fixed to the portion between the two integration reinforcing plates through bolts to be integrated with the main frame body. The upper ends of the two integration reinforcing plates extend out of the upper end face of the auxiliary frame body to form carriage limiting grooves respectively, and are of aligned edge structures or overturned edge structures. Supporting plates are correspondingly arranged on the outer sides of the tails of the two integration reinforcing plates. An outer overturning support is arranged on each supporting plate. Inner overturning supports are arranged at the portions, corresponding to the outer overturning supports, of longitudinal beams of the auxiliary frame body. By means of the main-auxiliary integrated frame, the production technology is simple, the assembling efficiency is high, maintaining and disassembling are convenient, and applicability is high.
