Conveyor Gallery Bridge Structural design 1

[StrP88]

I am looking for a source that kind of explain structural design of conveyor truss and trestles.
Also kind of struggling understanding the supports of conveyor on top of trestles? Whats a fixed support will look like and what a roller will look like on top of trestle?

How are these trusses just individual segments that will install individually on top of trestle? Do they connect them? Do we design the truss continuous over trestle?

What type of support do we use at each end of whole thing? Do we use the pinned on the very top? or on their bottom?

Any book points these things out? Most books I seen are about belt and mechanical side of conveyor rather that supporting structure?

Any article, book, power points, training? I appreciate your help

when you use the term "gallery", do you mean a box truss that surrounds the typical conveyor frame

That's correct. We call the truss housing conveyor as "gallery". A typical gallery section contains the conveyor stringer with carry idler/belt above, return idler/belt below,

36" wide walkway both sides for maintenance, and a cable tray hung under the roof.

Again thank you so very much for your excellent replies.
Couple more question:

I see that idlers sit everywhere not necessarily on the panel points of the truss conveyors? is that okay?

Or in gallery conveyors the conveyor gallery assembly sits on bottom truss struts, so is that strut a axial force member or it is a beam element?

The drive pulley and bottom pulley are they attached to the truss or they are not attached to the truss?

Also I see a triangle sort of frame at bottom of conveyors as a support, whats that ? Its like a rectangle triangle ? is that consider as support?

Thank you

Idler sits on stringer, stringer sits on truss node point transverse beam

The drive pulley and bottom pulley are they attached to the truss or they are not attached to the truss?

Pulley are heavy and dynamic impact so it's critical. Depending on what pulley, if it's drive pulley, the belt tension is huge and you need special heavy duty diagonal support.
If it's bend pulley and belt tension is not that big, you can use truss bottom transverse beam to support it.
