电梯制动器失效风险分析及其防范措施探讨

Analysis on Fault Risk of Elevator Brake and Discussion on the Preventive Measures

分析了电梯制动器使用过程中的安全风险,指出电梯制动器的失效原因。主要在于机械部件缺乏冗余度、机械部件磨损以及机械部件的卡阻。电梯制动器失效可能导致门区域的剪切(或挤压)事故以及冲顶(或蹾底)事故,造成人员和财产损失。为此提出了降低电梯制动器失效风险的对策措施。

The safety risk of elevator brake in use is analyzed.The fault reasons are pointed out mainly including redundancy lack,abrasion and jam of mechanical parts.The door-zone accidents of cut/nobbing and uprush/falling can be generated by elevator brake fault,which can take a toll for personal and property.The preventive measures for reducing fault risk of elevator brake is given.
