The invention discloses a crane hoisting adjusting device, and relates to the technical field of building hoisting technologies, the crane hoisting adjusting device comprises an adjusting fixing frame, a power assembly and suction cup assemblies located at the bottom of the adjusting fixing frame, the suction cup assemblies are symmetrically arranged on the two sides of the adjusting fixing frame, and the adjusting fixing frame comprises a suction cup lower frame; the power assembly comprises an electric push rod, the suction cup assembly comprises an outer suction cup, the outer suction cup comprises an outer side wall and an inner side wall, an annular cavity is formed between the inner side wall and the outer side wall, and the cavity can be filled with cooling liquid; the thickness of the outer side wall is 1.5-2 times that of the inner side wall, so that the cooling liquid in the cavity can cool the inner side wall of the suction cup, and meanwhile, the structural strength is improved; the sucker lower frame is fixedly connected with the outer sucker through a connecting piece, and the outer sucker can be adsorbed to the surface of an aluminum plate through downward pressing of the sucker lower frame. The technical effect that the temperature of the contact portion of the rubber suction cup and the aluminum plate can be reduced, and therefore rubber is prevented from being softened and particles are prevented from being embedded is achieved.
