Bolting Motorcycle Loader Advice
I have attached a picture and you can see the yellow screw rod I referenced that holds loader in place...one goes on each side. Pardon the picture of the bike thats in the pic...thats the only good picture I could find online to show the rod I was talking about.
The "bolt less angle screw rod set-up" is only keeping the load from sliding around the truck bed.... It doesn't really hold any of the weight from the bike on the lift... correct?
When loading and unloading the bike, the lift/bed handles the weight, not the "bolt less angle screw rod set-up".... correct...?
So if you bolt down the lift to the truck bed, the bolts are not bearing the weight of the lift/bike, but just keeping it from sliding around the truck bed, like the "bolt less angle screw rod set-up".
If that is true, wouldn't the bolt joint be used in "shear", rather than "tension"... ?
I believe a joint in tension is weaker than a joint in shear. Doesn't matter (much) what type of fastener, pop rivets, welding, bolts, it is stronger in shear than in tension.
I'm not an engineer, but I would think the rivnuts would do well for that application, without the need for backing plates... For piece of mind you could use grade 8 bolts..
Good luck with your decision...
You mentioned wing things on the ramp. See if the wings flat spots line up with the raised portion of the bed.
Most of the raised portions are 1 in to 1 1/4 in wide on the flat part. Drill holes through wings and bed 3/8 should be ok.
Use a 1/4 to 1/2 thick steel bar on the underside of the bed with drilled and tapped holes for the bolt to go into.
I made the steel bars ( 4 places ) 6 in long and put a good tack weld on each under the bed.
Tack welding will damage the paint an alternative I considered was to ad extra bolts at each end of 6in bars.
This worked me YMMV
Good Luck WP

Wouldn't just about any bolt-down system be as good if not better? As long as those rods are, to me they look like they could flex a bit...allow a bit of movement?
Plus...those rods look to be secured only to the stake pockets of the truck bed. Don't look to be fastened to anything "overly structural"
Bolts of any sort would be nice & snug, and as pointed out, are there more for shear strength. But again, I haven't seen one of these so I may way off.

Just me - I loaded lots of dirt bike and a few heavier Rice bikes with anything from a 2 x 10 to an ATV ramp and just ratchet strapped them down. My Ultra or other Harleys I own, won't be ging up an aluminum ramp, with a rail and no wheel chock. Even if I load, on & off, from a loading dock my truck will have a secured wheel chock. 800 pound shifting on a quick turn or emergency maneuver I wish you the best with bed rivet nut, those alignment rods, or whatever. Please remember to do another thread if it doesn't work out as you thought.
