The invention provides a lifting device and a mining dump truck. The lifting device comprises a lifting support and two lifting fixing seats. Two transverse end parts of the lifting support are respectively positioned above the two longitudinal beams; one lifting fixing seat is arranged between one transverse end part of the lifting support and the left longitudinal beam, and the other lifting fixing seat is arranged between the other transverse end part of the lifting support and the right longitudinal beam; the lifting fixing seat is fixedly connected with the longitudinal beam, and the lifting fixing seat is detachably connected with the transverse end part of the lifting support; the lifting fixing base is of a three-side-wrapped structure and comprises an outer vertical plate, an inner vertical plate and an upper mounting plate. The outer vertical plate is welded with the outer side vertical surface of the longitudinal beam; the inner vertical plate is welded with the vertical surface of the inner side of the longitudinal beam; the upper mounting plate is arranged above the top plane of the longitudinal beam, the bottom plane of the upper mounting plate is welded with the top planes of the outer vertical plate and the inner vertical plate, and the lifting support is connected with the upper mounting plate through a detachable part. It can be ensured that the assembling position of the lifting oil cylinder does not deviate.
