Abstract: The current armored equipment for the troops generally present the problem of its bottom out-of-gauge during railway transportation. For the problem above, the loading position of armored equipment is increased to the bottom gauge of Chinese railways by a heightening solution, and the maximum gauge width in the middle of railway is fully utilized in order to achieve the goal of not exceeding the gauge of armored equipment. The expression of determining whether the calculation points are out-of-gauge is derived by establishing a coordinate system, and the calculation points are determined. Then the value range of the elevated height Δh of equipment without out-of-gauge is calculated according to the constraints of the overrun equipment, the contour size of load, the boundary outline of railway limit, and the high center of gravity of heavy truck. The feasibility of the heightening solution to solve the problem of out-of-gauge railway transportation of armored equipment is verified.
