The invention discloses a vertical lifting mechanism and an engineering vehicle, and relates to the technical field of engineering machinery, the vertical lifting mechanism comprises a base, a carrier, a triangular seat, a first lower lifting arm, a first upper lifting arm, a first rocker, a lower limiting structure, an upper limiting structure and a first driving device, the first lower lifting arm is hinged to the base, and the other end of the first lower lifting arm is hinged to the triangular seat; one end of the first upper lifting arm is hinged to the carrier, and the other end of the first upper lifting arm is hinged to the triangular seat. One end of the first rocker is hinged to the base, and the other end of the first rocker is hinged to the middle of the first upper lifting arm. The lower limiting structure is hinged to the base and the triangular base so that the triangular base and the base can move in parallel. The upper limiting structure is hinged to the triangular base and the carrier so that the carrier and the triangular base can move in parallel. The first driving device is connected with the first lower lifting arm in a hinged mode, vertical lifting can be achieved, parallel movement can be kept, large loads and tipping torque can be borne, the structure is compact, and the occupied space is small.
