A dumper frame comprises a right longitudinal beam and a left longitudinal beam which are symmetrically arranged, and a bumper assembly, a front lower gantry beam, a second cross beam, a third cross beam, a middle rear cross beam assembly and a tail cross beam which are sequentially connected between the left longitudinal beam and the right longitudinal beam from front to back; the sizes of the box-shaped sections of the left longitudinal beam and the right longitudinal beam are kept unchanged from front to back; and at least one surface of the second cross beam, the third cross beam, the middle rear cross beam assembly and the tail cross beam overlaps the left longitudinal beam and the right longitudinal beam. According to the dumper frame, the torsional rigidity and strength are greatlyimproved, complex and changeable severe working conditions of a mine can be resisted, and the design service life is long. The invention further relates to a dump truck with the dump truck frame.

    一种自卸车车架,包括对称设置的右纵梁和左纵梁,从前到后依次连接在左纵梁和右纵梁之间的保险杠组件、前下龙门梁、第二横梁、第三横梁、中后横梁组件和尾横梁;左纵梁和右纵梁的箱型截面尺寸从前往后保持不变;第二横梁、第三横梁、中后横梁组件、尾横梁均至少一面与左纵梁和右纵梁搭接。本发明的自卸车车架极大地提升了扭转刚度和强度,能抵抗矿山复杂多变的恶劣工况,设计寿命长。本发明还涉及一种具有该自卸车车架的自卸车。
