Securing stacks of narrow equipment, off center

I had a bunch of gear on my trailer. Drove about sixty miles with this load. Stopped to return the aluminum conveyors and had to put the aluminum planks on top of the blue steel conveyors for the trip back to my shop. I kept the steel conveyors strapped, then used two blocks between first plank and conveyor and another two blocks between planks, then strapped over top of planks to trailer. Drove about three or four miles and the planks and top conveyor tipped. I caught it in the mirror and was able to improvise a new securement method for the rest of the trip, taking the planks off the conveyors.

When I got to my shop I realized the conveyors were now tipping again. I understand that a load that is strapped close to the edge of the trailer will want to move toward the center of the trailer because the strap will loosen if it moves in that direction. I guess I am wondering what I should do next time. Would wrapping the conveyors together first solve the problem or would the stack still tip toward the middle? I put the ratchets on the driver's side (close side) thinking the ratchet side will have more tension and will tend to pull harder, in order to compensate.

I'm at a loss. Thanks.

 

Thanks! I'll practice those techniques before I move these again.

 

I was looking at the photo I took in the rental yard and realized the only thing keeping the steel conveyors from toppling was this strap that I have traced in blue. It went between the steel conveyors and pulled up on the top conveyor as it made the bend.

Thanks.

 

Thanks, I plan to invest in more straps so I have enough for bundling things together and so forth. These have always been the most difficult types of loads for me - bunch of random tools and stuff, where it's hard to center things and the straps from one object interfere with deck space for placing another object.

I appreciate the replies from the pro drivers.

 

If I had a CB in the truck, I probably would've heard guys telling me my strap situation was a dumpster fire. Always wanted one...

 

Welp, I got some practice today.

 

Strapped under yellow straps and back to same side. Then used yellow conveyors as bulkhead for grapple bucket, which was then cinched to the steel hoppers at right in a similar manner, then yellow strap over it all.

I don’t have enough yellow straps on either trailer. Recommendations on where to buy them? As well as edge protectors.

Thanks.
