RE: elevator hoist beam

[Subject Prev][Subject Next][Thread Prev][Thread Next]
It depends on the size of the elevator.  The hoistbeam is provided to allow
installation and testing of the cab prior to having the actual elevator
lifting equipment installed and operational.  Simple span loaded at the
mid-point seems reasonable but 5k seems a bit light.  You can get elevator
info directly from Otis' home page
(http://www.otis.com/products/listing/0,1357,CLI1_PRT30,00.html).  The CAD
drawings should include cab weights rail force requirements etc.

does anyone know of a good design reference for elevator hoist beams?

my superior told me to load a simple span beam with a 5 kip point load
applied at the middle.  is that about it or is there more involved?
