I am assigning load limits for various trolley beams in our company, and I was hoping I could get some input on allowable deflections for lifting beams. I have had several sources tell me different things, but nobody gave me a reference to where they got their info.

I am assigning safety factors due to the allowable stress in the beams, however I think that there might be deflection limits that some beams are exceeding before reaching the maximum allowable stress.

I am very familiar with determining the allowable stresses, but not deflections. Are the deflection limits completely subjective to the loading conditions? Any help would be great.

Thanks
 
I don't know where the defection limits are. I remember that the last time I did this we ended up using about 1/3 of the allowed defection limits. Otherwise the beams looked like noodles.
