Summary:The utility model relates to a matching rack device for lifting transport machinery, which is mainly used for vertical transport in the building industry. The structure of the utility model is mainly composed of base supporting legs and brace bars, and forms an independent structure of a derrick. The utility model eliminates a manner that the derrick is fastened toward surrounding broad areas by steel cables when in construction. The independent structure of the utility model overcomes shortages that a construction ground is small, and a construction building is high; thus, steel cables can not be pulled to fasten the derrick. By the trial and the examination, the utility model has the advantages of safe structure, convenient operation and high recognition.
