The application relates to the technical field of bridge erection, in particular to a construction method of a bridge erecting machine and a single-arm bridge erecting machine. The construction method of the bridge erecting machine is as follows: when the construction line is a small curve section, the front supporting leg assembly and the middle supporting leg assembly are folded, the first horizontal moving mechanism is used to drive the front supporting leg assembly to move horizontally to the inside of the curve, the second horizontal moving mechanism is used to drive the middle supporting leg assembly to move horizontally to the outside of the curve, the first horizontal moving mechanism is used to drive the machine arm at the front supporting leg assembly to move horizontally to the inside of the curve when the front supporting leg assembly and the middle supporting leg assembly are supported, the second horizontal moving mechanism is used to drive the machine arm at the middle supporting leg assembly to move horizontally to the outside of the curve, and the centers of the two ends of the machine arm can be adjusted to coincide with the centers of the first bridge pier and the second bridge pier. Therefore, when the small curve girder erection is carried out, the bridge erecting machine does not need to be modified, the process of the bridge erecting machine passing through the small curve is simplified, the construction efficiency of the bridge erecting machine is improved, and the bridge erection time of the small curve section is reduced.
