Can anyone tell me how many restrictors have have seen removed due to the fact they either played up or broke in NORMAL usage, I have seen heaps that have been removed and others that due to the fact they have a contact on them caused continuous passengers to be trapped for no reason other than the contact was not adjusted to a critical position. Why do lifts really need a restrictor anyway when the gap between the sill and wall USUALLY isnt big enough to fall through when well flushing etc is fitted correctly.
