Use of J bolts on crane run system

Use of J bolts on crane run system

Use of J bolts on crane run system

(OP)
I have been asked to approve the use of the age old J bolts for the crane system in our shop. I don't like the J bolts since I keep finding them on the ground in the shop.
Does any one have any references I can look at about the pros and cons of J bolts.
I have the most current CMAA doucment and it is no help at all.

RE: Use of J bolts on crane run system

If you put them in, they work....if you don't put them in, they don't work so well!

As for failure mode, they have been known to straighten on pullout, but that's in an overload condition.

To me...not an issue...use them.

RE: Use of J bolts on crane run system

I would only use hook bolts for light duty applications, given they provide no lateral support to the rail. For heavier situations I would use rail clips.  

An expert is a man who has made all the mistakes which can be made in a very narrow field

RE: Use of J bolts on crane run system

Ignore my previous post!! I was thinking different j-bolt application.  Agree with RE.
