The steel-aluminum composite cab framework structure comprises an anti-collision frame and a rear aluminum alloy frame which are fixedly connected, the anti-collision frame comprises a double-A-column anti-collision beam, a front anti-collision beam, a stand column supporting beam and a top beam, and the double-A-column anti-collision beam comprises a right A-column anti-collision beam and a left A-column anti-collision beam which are symmetrically arranged; the right A-column anti-collision beam and the left A-column anti-collision beam are of an arc-shaped structure, the inner side of the right A-column anti-collision beam and the inner side of the left A-column anti-collision beam are both connected with the stand column supporting beams, the two ends of the top beam are connected with the top of the right A-column anti-collision beam and the top of the left A-column anti-collision beam respectively, and the two ends of the front anti-collision beam are connected with the front portion of the right A-column anti-collision beam and the front portion of the left A-column anti-collision beam respectively. The carbon steel anti-collision framework is compositely connected to the key collision face, and compared with a traditional cab framework welded by single carbon steel or aluminum alloy materials, collision capacity and light weight are both considered.
