Hanging a grain conveyor

[T C]

We are reusing a perry 30t conveyor in a new grain shed. It will hang from 3 rafters once in the shed
What is the best way to clamp brackets to the steel rafters.
Don't want to drill or weld.

Angle iron brackets clamped to the RSJ with Lindapters.

Like these, but may need a different length tail depending on thickness of flange

Lindapters all the way, different sized tails and two sizes washers will get you to the right size for your flange.
this is 8mm plate M12 Lindapters

Thanks the clips worked really well.
Next question is how to operate the slides.
I could use a pinion gear with a chain but could I use air rams?
