[0002] At present, small-scale railway construction and maintenance equipment has replaced manpower on the railway. The weight of these equipment ranges from a few tons to dozens of tons. The transfer of maintenance and construction equipment from the ground to the rails requires a transition pavement, the construction of a transition platform, or the finding of a nearby station level crossing. When the construction equipment fails on the railway and stops, it is necessary to find lifting equipment to lift the faulty equipment away from the railway. When it is close to the station, the steel wheel brake can be released for a short distance traction to enter the station auxiliary road.

[0003] However, the existing technology has high requirements on the transportation and rescue environment of construction equipment, the road conditions at the rescue site, and the timeliness of rescue equipment, and has great limitations.
