The invention relates to a method and a device for lifting weights on the top floor of a super high-rise building, wherein the device comprises a stand, a fixed mast, a movable mast, a
ball joint, a guy cable combined disk, a hoisting block, an amplitude-change block, a stabilizing bar, a guy cable and a prestressed drag line; the stabilizing bar, the stand, the guy cable combined disk and the fixed mast are utilized to form a stable support structure, and meanwhile, prestressing force applies to the guy cable and the prestressed drag line; when weights are lifted, the stabilizing bar is in a state with small stress or no stress and generates sufficient stability and safeguard; and a
guideline resists transverse wind loads. The invention has a simple process method, and the device has reasonable structure, simple and convenient operation, small overall weight, flexible movement, convenient
assembly, disassembly, entrance and exit,
safe operation, low cost and short construction period, and can realize the integral lifting of
overweight objects on the top floor of the super high-rise building, overcome the difficulty of the integral lifting of the
overweight objects on the top floor of the super high-rise building which can not be finished by traditional construction elevators,
tower cranes and traveling cranes, solve the difficult problem puzzling the technical field of construction and installation for a long time, and realize standardized and
mass large-scale production.
