Basic Information
Scope
During the construction phase of super high-rise buildings, there are several characteristics, including high working height, intensive cross-processes, long construction period, and high intensity of personnel and material flow. Among them, the vertical transportation system runs through the entire process from foundation construction, main structure construction, mechanical and electrical installation, decoration and finishing to completion and handover. It is a key production system that affects the safety level of construction and the ability to meet project deadlines. Vertical transportation is typically composed of tower cranes, construction elevators, material hoists, winches, temporary elevators, unloading platforms, and horizontal transfer facilities. Its operating state directly relates to personnel safety, major equipment safety, and the prevention and control of compound risks such as falling objects from height, structural stress disturbance, fire, and electric shock. In super high-rise construction, the risks of vertical transportation are characterized by significant systemicity and coupling: First, high-altitude operations combined with environmental factors such as strong winds, thunderstorms, and low-temperature icing can easily induce accidents such as tower crane instability, load swing and collision, and abnormal stress on elevator guide rails. Second, multiple equipment and work areas operating in parallel can easily lead to cross-operation interference, material blockages, overloading, and illegal command and operation due to the lack of unified spatial and temporal coordination control. Third, frequent installation and disassembly of equipment and climbing/lifting operations make temporary structures and attachment systems highly sensitive to installation quality, detection and verification, and maintenance management. Any control failure in these aspects may lead to major accidents involving mass casualties. Fourth, as a bottleneck resource
