Ultralow type platform wagon for sandblasting oil tank of large power transformer

The invention relates to an ultralow type platform wagon for sandblasting an oil tank of a large power transformer and belongs to the technical field of special transportation equipment for sandblasting, painting and drying super-large and ultrahigh oil tanks. In the technical scheme, the ultralow type platform wagon comprises three parts, namely a bodywork (2), a wheel system (3) and a rigid cross beam (1), wherein the rigid cross beam is connected with the bodywork and the wheel system; the rigid cross beam connected with an installation plane of the wheel system is positioned above the bodywork, so that most wheels of the wheel system are positioned in the bodywork instead of being positioned below the bodywork; therefore, a carrying surface of the bodywork is lower than the installation plane of the wheel system, and the aim of reducing the height of the bodywork is fulfilled. The ultralow type platform wagon has the advantages that: under the condition of not changing workshop equipment, the height of th
