所谓绞绳是指在吊运过程中滑轮组钢丝绳有拧成一股大麻花状的倾向。发生绞绳的原因是普通单向反捻制的钢丝绳在受力后会产生松向转动力矩,简称反拨力或破劲力。该力的大小与绳径、材质、物重、新旧程度等因素有密切关系,目前尚无现成资料可查,其近似数据可在地面用模拟方法以弹簧秤测量。关于绞绳现象,实际在地面吊运作业中也时有发生,只是一般绳子较细,又是在明处操作,可以随时扶转物件,而使其不致发生安全问题。再者绳子用久
The so-called twisted rope means that during the process of lifting, the rope group has the tendency of twisted into a cannabis-like shape. The reason for the occurrence of stranding ropes is that ordinary one-way anti-twisting steel ropes will generate loose rotation torque after being forced, referred to as reverse force or broken force. The size of the force and rope diameter, material, material weight, the degree of old and new and other factors are closely related, there is no ready-made information available, the approximate data can be simulated on the ground using spring scales to measure. On the phenomenon of twisted rope, the actual operation of lifting the ground from time to time have occurred, but the general rope smaller, but also in the bright operation, you can always turn things around, leaving it will not occur security issues. Furthermore, the rope with a long time
