For the gantry crane with cantilever, its cantilever camber value has a great influence on the operation and stop reliability of the lifting trolley, which is an important performance index of the bearing structure of the equipment. When the height of the outriggers on both sides of the gantry crane is inconsistent, the vertical height difference measured at the cantilever end is not the actual upwarping of the equipment, and the numerical change caused by the height difference of the outriggers needs to be corrected. In this paper, the calculation formula of the upwarping degree based on the transformation of coordinate system is proposed, which can accurately express the upwarping degree of the cantilever. Based on this, the simplified formula is derived and the scope of application is limited, which is suitable for the inspection and calculation in engineering practice, and the error is within the allowable range.
