Abstract: A lifting device for building a steel structure hoistway and a method for building a steel structure hoistway. The lifting device includes a lifting mechanism and a crane mechanism. The lifting mechanism includes a bottom platform, a middle platform and a top platform. The crane mechanism is arranged on the top platform of the lifting mechanism, and includes a base and a crane on the base. The base is arranged on the top platform and is rotatable relative to the top platform along a vertical axis, and the hanger frame of the crane is movable between a vertical orientation and an inclined orientation. The lifting mechanism is configured to ascend and descend in the constructed steel structure hoistway, and the crane mechanism is configured to lift building materials, such as steel beams, steel columns, etc., for use in building the steel structure hoistway to their designed installation locations.
