[0002] The core tube of a super high-rise building is a crucial construction element, directly impacting the overall project's quality, schedule, and cost. Lifting steel platforms, with their high load-bearing capacity, rapid construction speed, high safety performance, and high integration, have become the mainstream construction equipment for super high-rise building core tube construction.
