D-ring mounting angle

[bdog]

I am going to weld some D-rings like this on my dozer to make chaining it down easier. I have the same model dozer as the one pictured and there is a company that puts rings like this on them but I will be doing it myself. I figure it will be a good project to learn how to use my harbor freight 110v wire welder I got for Christmas.

The chains attaching it to the trailer will be going out and down at an approximate 45 degree angle to the front and back.

Should I just mount the rings as pictured or would it be better to mount them at a 45 degree angle? The d rings obviously pivot but if mounted horizontally but pulling forward or backward seems like it would want to twist them. The ones I got are 1” and rated for something like 30k each which is more than the whole machine weighs so I doubt I will hurt them but it seems like they would be stronger and put less stress on the welds if oriented correctly with the load.

I'm no certified welder by any means, but I'd not even attempt that heavy of iron w/ a 110V HF welder, IMHO you're gonna hit the duty cycle trip a lot, and likely not get sufficient penetration.

Given the discussions going on safe load restraint, do you really want to risk that on a light duty hobby welder? I hope not for others on the roads sake.

HF welders are great, I used one for years, but I also knew it's limits and something that heavy I'd only attempt w/ stick or a big boy MIG. Just my opinion, YMMV

For God's sake don't use that welder!:thumbdown::thumbdown::thumbdown::thumbdown: Have someone with a 220-volt welder do the welding.

I was kidding guys. I will be using my V350 Pro and either stick it with 7018 or use dual shield through my LN-25.

Curious about the angle though.

I was kidding guys.

Don't do that! You almost gave me a heart attack!:laughing:
I have no idea about the angle of the D-rings.

My thoughts on the angle, if you angle it it's gonna have some tendency to extend and fill w/ crud as it is expelled from the tracks, as in the pic it's gonna hang that way. As big as they are compared to load, I doubt it makes much difference strength wise, so I'd opt for as in the pic myself. Obviously, others believe as in the pic is acceptable, so don't re-invent the wheel.

And good to hear on welding.

I knew you had to be kidding!

Count me as another vote for stick with 7018, exactly like the picture.

I'm with you on this one. Hanging down is the best because otherwise they will catch on things and the strength is not an issue (If the welds are good - just kidding).

Why bother? Just hook the chain or binder on the inside edge of the pad, 4 corners..done, unless Texas requires one on the blade
