昆山市传动链厂原是昆山最大的国企昆山凯意纺机集团的一个分厂，专门从事纺织机械链条的研发和制造，从1989年开始与上海大隆机器厂合作生产自动扶梯梯级链，1991年底直接为上海迅达电梯有限公司供应梯级链，是国内第一家通过奥地利沃德海姆厂检测的公司。1993年昆山市传动链厂转资独立，更名为昆山传动链厂有限公司，成为继上海大隆之后的中国第二家梯级链生产商。1997年到2004是通力在中国的唯一的梯级链供应商，2004年由于通力总部的要求，梯级链集中到杭州沃尔夫（ULF）采购。后来东华和沃尔夫分手，东华成了通力的梯级链供应商。特别声明，通力把梯级链转到沃尔夫既不是昆山传动链厂的质量问题，也不是交货的问题，到目前还没有得到通力前线关于我们的链条的质量反馈。 The history of Kunshan transmission chain factory Kunshan transmission chain factory used to be one subsidiary of KunshanKaiyi textile group company(the biggest state-owned company in Kunshan) and was specialized in chain design and manufacturing. Starting from 1989, Kunshan transmission chain factory cooperated with Shanghai Dalong machine factory to produce transmission chain for escalators.
