电梯困人维修员应半小时内到场

2017-08-28 06:16:53   中国青年网

本报讯(记者唐煜 通讯员胡琼之)昨悉,我市日前首次发布电梯维保质量监督抽查标准,在严重隐患和重大问题清单中,“接到电梯困人故障报告后,维保人员抵达救援现场时间超过30分钟”被列首位。

截至2016年底,武汉共有电梯逾8.7万部,且每年以18%的速度增长,包括办公区、居民区、地铁、超市的扶梯和垂直电梯等。

市质监局介绍,该标准规范了维保质量第三方监督机构工作,明确维保监督抽查工作的流程、对象、内容及总体结论要求。该标准中,曳引驱动电梯和自动扶梯的严重隐患和重大问题共有34项,如维保人员未取得相应的《特种设备作业人员证》;电梯运行有严重不正常异响、抖动;平层准确度超标;紧急停止装置失效;防止门夹人的保护装置失效;缓冲装置损坏严重;轿内报警装置失效等,都有严重隐患和重大问题。

该标准对电梯维保质量监督抽查内容、要求与方法,均有规定。其中,电梯维保质量监督抽查仪器设备和计量器具就有18种,并制定了测量范围或精度要求。比如,悬挂装置、补偿装置的磨损、断丝、变形等情况,要用放大镜全长检查,并用游标卡尺测量钢丝绳直径。同时,还增加了电梯试验的内容,如曳引驱动电梯的空载运行试验、消防返回功能试验、上行制动试验、平衡系数试验;自动扶梯扶手带运行同步试验和制动距离试验。

据介绍,该标准对监督抽查情况分为无不符合项、存在不符合项和存在严重不符合项3种,并制定相关存在严重不符合项清单明确范围,将抽查中发现的问题分级,便于电梯监管部门进行分类监管和处置。
