在钢结构电视塔或其它高耸钢塔安装方法中,杆件组装法因其机具设备能够重复利用、经济效益比较好而多被采用。但组装架设200m左右钢塔,若采用特大型塔吊,设备费用昂贵;采用临机拔杆土法吊装或采用外围环形轨道式塔吊配合中心回转式悬挂塔吊二次接力吊装法,通常存在设备的吊装性能差、环节多、操作不安全及辅助工作量大、经
In the method of installing a steel structure television tower or other high-rise steel towers, the rod assembly method is often used because its implement equipment can be reused and the economic efficiency is relatively good. However, erecting and erecting a steel tower of about 200m, if using an oversized tower crane, the equipment costs are expensive; using the machine-lifting pole method for hoisting or the use of a peripheral circular orbital tower crane with the central rotary lift tower crane for secondary relay hoisting method, there is usually lifting performance of the equipment. Poor, many links, unsafe operation, and heavy workload
