目前 ,在塔式起重机使用中普遍存在主卷扬钢丝绳排序紊乱现象 ,致使钢丝绳相互挤压而产生异型变形 ,使钢丝绳提前报废 ,造成极大浪费。钢丝绳排序紊乱的主要原因是受塔机平衡臂结构的制约 ,即从塔顶导向滑轮到主卷扬卷筒的距离小 ,钢丝绳能够规则排序所要求的角度达不到。为改 At present, there is a widespread disorder of the ropes in the main winch during the operation of tower cranes, causing the ropes to extrude into each other and generate abnormal deformation, which leads to the early scrap of the ropes, resulting in great waste. Rope disorder disorder is mainly due to the tower crane balance arm structure constraints, that is, from the top of the guide pulley pulley to the main winch distance is small, the rope can be ordered to order the angle required to reach.
