中新网上海4月29日电?(记者?郑莹莹?陈婷婷)上海市质监局副局长沈伟民29日在此间透露，上海地铁4月2日发生的自动扶梯事故经初步调查，直接原因是自动扶梯驱动链条断裂所致。
他进一步解释说，该驱动链条链接方式采用的是过渡链板的连接方式，过渡链板失效方式为疲劳断裂，具体原因还在进一步试验和分析中。
4月2日早上8点20分，在上海地铁静安寺站的换乘通道内一部上行方向自动扶梯突然倒行，导致十几名乘客摔倒受伤。
发生故障的自动扶梯制造单位为广州奥的斯电梯有限公司，由上海奥的斯电梯有限公司安装保养分公司负责日常保养维修。
沈伟民表示，事故是否与维保不利有关还在调查中，不好直接关联。
这并非奥的斯第一次出事故，2011年7月，北京地铁4号线动物园站一上行自动扶梯突然下行，致1名乘客死亡，28名乘客受伤。事故直接原因是由于固定零件损坏，扶梯驱动主机发生位移，造成驱动链条脱落，扶梯下滑。
沈伟民在采访中称，上海的奥的斯电梯型号与北京此前出事故的型号不同，北京出事故的奥的斯电梯型号当时上海已全面整顿并弥补，现在出现问题的是另一型号，上海将对潜在危险进行进一步排摸。(完)
