Crane lifting appliance with gravity center self-adaption and data storage functions

The invention relates to the field of crane lifting appliances, in particular to a crane lifting appliance with gravity center self-adaption and data storage functions, which comprises a mounting plate, the mounting plate comprises lifting frames fixedly welded on two sides of a plate body of the mounting plate, a driving unit is arranged on the upper surface of the mounting plate, and a gravity center adjusting unit is slidably arranged on the driving unit. Roller guide rails are symmetrically arranged on the upper surface of the mounting plate body and located on the front side and the rear side of the driving unit, a horizontal testing mechanism is arranged in the middle of the surface of the bottom end of the mounting plate body, and the horizontal testing mechanism can reflect whether the mounting plate is in a horizontal state or not; the mounting base is displaced through the driving motor, so that the balance weight disc moves, the gravity center of the mounting plate is adjusted away, the whole lifti
