ASME 17.1-2000 6.1.6.5 Missing Step Device. This requirement will prevent an escalator from continuing to run if a step is missing. It will prevent a void from a missing step to emerge form under the comb. This requirement was adopted because of the seriousness of the injury that results from stepping into the gap of a missing step, and the fact that a passenger would not see the gap until starting to step into it. 注:手上能找到的ASME 17.1最早版本是2000版,所以美标就摘录2000版。 后续版本ASME 17.1均包含此项要求。
EN 115-1:2008 5.3.6 Missing step or pallet device A missing step/pallet (see Table 6 k)) shall be detected and the escalator/moving walks stopped before the gap(resulting from the missing step/pallet) emerges from the comb. This shall be ensured by a device provided at each driving and return station. 注:后续版本EN 115-1均包含此项要求。
GB 16899-2011 5.3.6 梯级或踏板缺失监测装置 自动扶梯和自动人行道应能通过装设在驱动站和转向站的装置检测梯级或踏板的缺失[见表6的k)],并应在缺口(由梯级或踏板缺失而导致的)从梳齿板位置出现之前停止。 注:GB 16899-2011为现行版本。
