在海洋调查和施工中,常常在船上或岸上用钢丝绳代替人把仪器或设备送到预定的地点位置上,进行海洋观测或海洋作业。由于制作方法等原因,钢丝绳在负荷状态下会产生扭矩,这种扭矩是非常有害的,它会使钢丝绳在负荷状态下打结甚至破断,从而造成仪器设备的损失以至人身伤亡。因此人们发明了一种可以释放扭矩的转环,串接在钢丝绳的中 In the course of marine surveys and construction, wire ropes are often used on ships or on shore to replace the person with the apparatus or equipment at a predetermined spot for marine observation or marine operations. Due to the manufacturing method and other reasons, the wire rope will generate torque when under load. Such torque is very harmful. It will cause the wire rope to be tied or even broken under load, resulting in loss of equipment and even personal injury. So people have invented a ring can release torque, connected in series in the rope
