Dump trailer D-rings

[4570Man]

Depend's on how thick the ramp material is AND greatest force ever expected to be put on D-ring. In pic,ring is pushed toward rear and ramp is against front of ring. Tiedowns will pull ring foward against ramp and enough pressure will damage ramp. No big deal but you strick me as not wanting another problem.

It doesn’t seem like any manufacturer knows how to put on a D ring. They’re rated for an enormous load straight pull but only a small fraction of that sideways. They should be 45 degrease to make a tie down pull as straight as possible.

A thinly veiled ploy to sell snatch blocks as additional options.:laughing:

OK here's my mock up. Am I on the right track or do you see any problems. Going for a "ramp" so the debris fly's OVER the D-rings.

Looks like the simplest solution to try before you really start re inventing the tie down.

If your mainly hauling const. junk, I was thinking about a smooth floor (but with a 1 1/4" hole) and tying down with chains without a hook on one end by cutting off the d rings and recessing in some "banjo eye's" in place. Looks like you have a structural member there to at least have one side of the eye to weld to .

Yes we're on the same page here.

I was also thinking maybe cutting off the D rings making the floor smooth then cutting a 3" hole on the side of the dump
big enough to put a chain hook through. Then istall the D-rings on the outside of the dump trailer. Maybe a door to bolt shut when the D ring is not used.

Another option, but they still have lips but I could grind them down smooth. Only problem these have low ratings 1,600 pounds compared to 6-15K on the other.

After you brought that up it got me thinking why would they do that.
Then it hit me. When I load mu tractor it goes all the way to the tail gate
os when I connect a chain to one D- ring and connect to the far side of the
rear of the tractor. Next chain cris crosses the other chain to the other Dring.
They would be actually attached at a 45. Now did they do that on purpose and they
are that smart or was it a huge mistake.
The two front one are installed straight into the trailer.

Having said that if I secure anything shorter than the read of the trailer
then you're concern comes to being and I would be sideways.

Guess I can't tie anything dow that is short

My D-rings are on the walls. It doesn’t completely get rid of the issue you are describing, but it usually isn’t an issue.

I doubt that angle of D-ring mounting make's much difference when it come's to load hanging up while dumping. Sadly,providing optimum D-ring mounting angle for various loads requires additional rings that interfer with load sliding out if rings are on floor. It's the penalty you pay when pressing dump trailers into flatbed service. Dump beds aren't desighned to carry their load on 4 small spots then have an additional 10k to 20k of down force from tiedowns. In effect,the floor is carrying 2 or 3 times it's desighn weight concentrated on 3 or 4 sq feet instead of spread over 75-80 sq feet. If that isn't enough to warp the bed,15k in opposite direction might. Point is that 12k D-rings aren't going to break from improper angle unless holding a 9k-10k tractor that shouldn't be hauled in first place. At any rate,I believe the ramps will help with loads getting snagged.
