多绳轮绞车的提升钢丝绳在使用中缩径和断丝超出标准或达到规定的使用期限,必须进行更换。以往施工,各地方法虽有不同,但都必须设置数台稳车作为起吊提升容器和下放新钢丝绳之用。因提升容器一般都比较重,必须选用提升能力10吨以上的稳车并加滑车组方可满足起吊要求。稳车的基础、安装和架设滑车组的承挂梁等特别费工费时。山东兖州兴隆庄煤矿副井井塔设两套瑞典6绳摩擦轮直径2.8米绞车,一套为双罐笼,一套为单罐笼带平衡锤,在1981年6月提升钢丝绳全部进行了更换。因井塔东西侧为进出车道所占,南北两侧被等候室和环
Multi-rope winch lifting wire rope diameter in use and broken wire exceeds the standard or the specified period of use, must be replaced. In the past construction, although different methods around, but must be set to stabilize the number of vehicles as lifting the container and the decentralization of new wire rope use. Due to enhance the container are generally heavier, must be selected to enhance the capacity of more than 10 tons of steady car and add the trolley group to meet the lifting requirements. The basis for stabilizing the vehicle, the installation and erection of the trolley beam, etc., are particularly time-consuming. Shandong Yanzhou Xinglongzhuang coal mine shaft tower set up two sets of Sweden 6-rope friction wheel diameter of 2.8 meters winch, a double cage, a single cage with a counterbalance hammer, lifting wire rope in June 1981 all were replaced. East and west side of the tower due to access lane, North and South on both sides of the waiting room and ring
