Bolting of Crane Rail
Bolting of Crane Rail
(OP)
I'm working on a project replacing a telescoping conveyor boom. The rail is attached to the underside of the boom truss. The original rail was riveted through the base of the rail into the double angle bottom chord. We are using a WT as the new chord but still want to bolt the base of the rail directly to the tee. Is there any reason this cannot be done? Using clips would be more expensive and would require a wider/heavier section to make the attachment. Of course the clip manufacturers want you to use their clips but I know you can order rail that is drilled. Also, is there any information or guidance on bolt spacing out there?

Here is the rail attachment section. The flange would have to be wider and the tee section heavier to allow the attachment of the rail using clips.

That might be interesting to know, in order to comment on the fixation of the rail.
If I read your drawing correct, your rail is equivalent to 40kg/metre, which is about 2/3 of trainway size rails.
Does your application really needs such heavy rail?
Wouldn't flat bar (say, 1" square) suffice?

... It won't be quite as easy as installing crane rail with hook bolts on top of a W runway, where gravity helps to stabilize the crane rail until you can adjust and tighten the nuts. Your contractor might need shoring or large clamps for that purpose, unless they can invert the entire truss for a few hours.

I'm thinking you might need to add a flange to the web of the WT to prevent buckling.
