~~~~~~How do we know that the pins aren't stronger than the bolts that you might replace them with???~~~~~

Ron, Not to worry. I'd leave it as it is or at most replace the pins with grade 5 bolts if the pin steel is in question. That configuration is better than many I've seen. Welding a piece of chain directly to the frame rails is not necessarily better, assuming your slotted bracket is of sufficient thickness and properly welded.

What I am getting at is that no one knows what quality or grade these lynch pins are. I have had them that the springs are so strong you have to work hard to open them and watch your fingers when you close them. Either way, I do like this setup on the trailer. )</font>
Exactly!!!
JerryG, you hit it also!! /forums/images/graemlins/laugh.gif
I can't figure out what all the fuss is about /forums/images/graemlins/confused.gif It's not like this is a "big" trailer.

To fail from pure pulling, the pin would have to sheer through or the plate around the slot would have to bend such that the pin could bend and pull through.
Even assuming the cheapest grades of steel involved, the geometries are such that the forces would need to be in the 10's of thousands of pounds. Probably higher than the chain itself is rated for.
I would be mostly worried about the spring-ring getting snagged on something or somehow bouncing loose. On tractor implements, lynch pins get lost all the time being dragged through brush and stuff. On the trailer, its probably less likely.

Think I would just pull one more chain link up on each side and slap a padlock on it. I’d still use the lynch pins but the lock would give me peace of mind and make sure someone else didn’t think they needed my chains more than me. As smart as we are here on TBN I’d bet the manufacture of the trailer has done enough figuring to feel safe enough from liability issues to continue to use the set up.
