在建筑工地上,不是随时都能够选到适合所需刚性要求的钢丝绳并使它处于中间状态,也就是将它在整个长度上(100—150米)拉直。经常是从绳卷中直接取出就进行缠绕,因此常常发生载重滑输组的扭转现象。为了避免上述现象的发生,切博克薩累第一建筑公司采用了一个简单的装置一万向吊环(图1与图2)。万向吊环在СБК—1,C-419, At construction sites, it is not always possible to choose a rope suitable for the required rigidity and to center it, ie to straighten it over the entire length (100-150 m). It is often the case that the windings are simply taken out and wound, so that the twisting of the load-slip group often occurs. In order to avoid this, Cheboksary First Construction Company adopted a simple device-universal ring (Figures 1 and 2). Universal rings in СБК-1, C-419,
