serrated teeth imbedment in steel
working on a dynamic safety device with serrated teeth. looking for design or test information on serrated teeth imbedment into steel.

imbedment? hmmm, how do you plan on imbedding them? normally, things are not imbedded, they are welded and/or bolted to steel. will the teeth be cutting anything or are they ratchet stops?
we need a bit more information.

the application for the safety device is to stop a free fall of a vertical traveling platform. the safety device is a mechanical backup system and is replaced after one use. the safety device is a rotating cam with serrated teeth. in a free fall the cam teeth rotate onto a w-section flange. the hardened teeth "imbed" and lock onto the flange. thru testing we have established a cam load limit. i'm look for information to understand the dynamics and limits for a redesign of the cam teeth.
you might try re-posting your message in the mechanical engineer's forum. i can't say that i have any experience in designing something to rip into structural steel. i usually spend my time trying to prevent that sort of thing. btw, i sure hope that the i beam gets replaced also. if not, let me know the address of the building in which your putting this elevator. i'd like to avoid it.
you might also see if their is an elevator association. they should have info on safety devices.
