About a month ago I had a chat with an elevator repair technician. We chatted in the elevator as I rode from floor 1 to floor 11. (Actually - he invited me on the elevator on floor 1. He saw me waiting for the elevator; so he took me up to 11 as he went to the top floor; apparently he was doing repair work up in the elevator mechanical room on the roof).
I started to interrogate him. :-) Are you a elevator guy? Yes Can I ask you some questions? You dont have to answer if you dont want to - (I think I gave him the option to opt out of the interrogation - he was very friendly - I never got the impression that I was really imposing on him) No problem The elevator is pulled by cables that go around a pulley connected to a big motor on the roof, and to a counter balance - right? Yes - the counter balance is set at 80% (some percentage - maybe 85% or 90%) of the (rated) weight Can someone move the elevator up and down by hand - since the system is balanced? You have an emergency generator If the emergency generator fails, could someone move the elevator by hand? Yes - maybe - (he said something about releasing safety brake and moving the car) So, in theory, it is possible to move the car by hand? We sometimes do it with a small drill --------------------------------------- That is the conversation to this best of my recollection. When he said "small drill" - I assume he meant a common, small, hand held, battery powered electric drill - like for driving screws. I wonder if a small drill could move a EMT, and a stretcher with a patient, from floor 14 to floor 1 safely? I wonder if a small generator from a fire truck could run the elevator in a pinch? -- You received this message because you are subscribed to the Google Groups "massfire" group.
