The invention provides a mining dump truck lifting seat. The mining dump truck lifting seat comprises a left longitudinal beam, a right longitudinal beam, a left lifting arc plate and a right liftingarc plate. The left longitudinal beam and the right longitudinal beam are arranged at the bottom of a carriage, and the rear ends of the left longitudinal beam and the right longitudinal beam are hinged to the carriage. The left lifting arc plate and the right lifting arc plate are fixedly mounted at the bottoms of the left longitudinal beam and the right longitudinal beam correspondingly. The left lifting arc plate and the right lifting arc plate are of the same structure integrally machined and formed by a whole steel plate, the bottom of the left lifting arc plate and the bottom of the right lifting arc plate are fixedly connected to the two ends of a middle pipe respectively, and lifting fixing bases are fixedly arranged at the two ends of the middle pipe respectively. A lifting fixingpin shaft used for being hinged to a lifting oil cylinder is arranged in an axial inner hole of each lifting fixing base. The mining dump truck lifting seat is simple and light in structure, abrupt change of the cross sections of the longitudinal beams can be reduced, stress concentration points are removed, and unbalance loading in the lifting process is avoided.
