起重机用单股钢丝绳起吊重物时,重物的摆动和转动通常是不可避免的。从安全的角度出发,海上起重船很有必要装设防止重物摆动和转动的装置。这种装置的海上实验是在浦福风级3级的海上气象条件下进行的,被起吊的重物是一艘7吨重的潜水船。从实验时的情况来看,这类装置对于整个起重船的安全作业是不可缺少 When a crane lifts a heavy object with a single wire rope, it is usually unavoidable to swing and rotate the heavy object. From a safety point of view, it is necessary for a marine crane vessel to be equipped with a device that prevents the weight from swinging and turning. The marine experiment at this facility was carried out at Puff Grade 3 offshore weather conditions and the lifted weight was a 7 tonne submersible vessel. From the experimental point of view, such devices are indispensable for the safe operation of the entire crane vessel
