钢丝绳用楔形接头这一通用组件进行钢丝绳绳端固定或连接,性能牢固可靠,制造安装方法简单,更换钢丝绳方便等优点,被人们广泛应用。汽车起重机臂头处起升机构钢丝绳绳端固定通常采用这种固定方式,在起重吊运作业中起到应有的作用。但笔者在检验工作中发现多起汽车起重机臂头处起升机构钢丝绳绳端固定楔形接头下缘部位钢丝绳出现非常严重的断丝、局部聚集或整股、多股 Wire rope with wedge joints of the common components of the rope end of the rope fixed or connected, solid performance, easy installation, manufacture and installation of simple, easy replacement wire rope, etc., are widely used. Crane arm at the head lifting mechanism Wire rope rope end fixed usually use this fixed way, lifting crane operation play its due role. However, the author found in the inspection more than the crane arm at the head lifting mechanism rope end fixed wedge connector wire rope at the lower part of the emergence of a very serious broken wire, local aggregation or whole stock,
