随着建筑物向高层发展,吊篮架逐渐兴起。其在理论上的合理性是明显的。因为吊篮主要承重构件是钢丝绳,其强度高、重量轻,在受拉条件下是最有利的。吊篮架最初采用的是“爬升式”,也就是以钢丝绳做导轨(同时承重),用手搬葫芦或倒链提升。由于上两种提升机具的故障以及在提升操作时不慎,易于发生事故。在此基 With the development of buildings to higher levels, hanging baskets have gradually emerged. Its theoretical rationality is obvious. Because the main load-bearing structure of the basket is a steel wire rope, its strength and light weight are the most favorable under tension conditions. The hanging basket was originally used as a “climb type”, which means that the wire rope is used as the guide rail (simultaneous load bearing), and the lifting of the hoist or the reverse chain is performed by hand. Due to the failure of the above two hoisting equipments and carelessness during the lifting operation, accidents are prone to occur. In this base
