Questions for JB4310

JB4310,

In the "Why four binders" thread, you posted a couple of pic of your JD chained to the trailer. Two questions:

What are the front chains attached to?
What is the attachment point for the shackles in the rear?

Thanks,
-John

I'm not JB4310 but the front is a weight bracket bolted to the frame and the rear I don't know my 4310 does not have those but should.

The back attachment points are his backhoe frame with clevis's in the top mounting holes.

I was thinking the weight bracket in front, but wasn't sure. I would have never figured out the rear was a backhoe frame.

Thanks guys!

Sorry, I just noticed this thread, yes the back shackles are attached to my back hoe frame, those are 5/8 alloy shackles rated at 5 ton WWL. I don't know where else I would connect to on the rear of this tractor, where are other 4310 owners connecting to back there?

The front is hooked right on the frame behind the weight bracket, I don't think it's bolted, I think it's all part of the frame, not sure though.

One thing I just read about Aggregate working load limit (AWLL), we've been discussing requirements of securing loads. I was under the assumption that the sum of the chains had to equal or be greater than the load secured, but read recently that it appears that only half the weight of the load has to be considered (the AWLL). I could be wrong as I didn't completely understand what I was reading. Anyone Know for Sure. I guess it kinda makes sense since your not lifting the load, only securing it.

I may bring this up in the thread that has discussed this topic.

See page # 29 and 30 of this document, large file, sorry.

If you are using the working load limit for your calculations you only have to figure for half of the weight. That is because the breaking strength is a whole lot higher. When using breaking strength you go with 1.5 of the weight.

Thanks for the pics JB.

That front frame location is going to get another look on my tractor the next time I haul it. For the rear, I don't have a backhoe frame, so until I see something that makes more sense, I'll continue using the draw bar.

Thanks,
