To clarify, atroll is taling about the zig-zag gizmo not the Hitchcraft tie.

Should try the Hitchcraft tie. Several people tested and the Monster holds 500 lbs (but requires rope .25" or more). Weighs 3 oz, and you really only need one to have easy adjustment. Use a bowline...

I'm glad you received them already. It's the first order I had from AUS.
I hope the parts work for you. I assume you are not using 1/8" line, for which I do not recommend the Mini ropetie. The...

Thanks for the vote of confidence. However that is not likely to happen anytime soon. As it is I jumped off the deep end with this design which is my first attempt to sell my own product. I started...

I take it that's an endorsement. Thanks for trying my product. The key is not to overtension the hammock (under 30 deg loaded) since it will drive the load beyond the safe working load. I would be...

Pretty impressive stuff. Being a lazy engineer I try to simplify things first until I get a very simple formula like: w*2*0.5=w
Of course, you might say that a black box may not be as comfortable as...

Dgrav, here's my delayed response - you probably got the answer in the meantime.
At 45deg , a 200lb load would produce 141 lb tension on each rope. If the hammock is level the load is equally split...

It seems that a number of users like to tighten the hammock as much as possible. It's still hard to put a value on it. When several of the elements connected are somewhat flexible a hammock that is...

Thanks for bringing in some clarity!

I am interested in the forces that would be applied to the hitchcraft tie when it is used to tension the rope, outside the ridgeline attachment. From that point of view the only thing that I am...

Please, let's back up TeeDee. I don't think you are understanding me.
Let me follow your example. If I cut the ridgeline the angle of the ropes outside will increase, meaning that the tension on the...

Are you referring to the life of the product?
I don't have much data, but I have a demo that has been used for 100-150 cycles and the teeth start to show some wear marks. I would estimate that they...

TeeDee - I'm afraid I may not have made myself clear. When I say ignore the ridgeline I don't mean that it makes no difference. What I mean is that when you analize the forces you can cut the...

Teedee - I did ignore the ridgeline, and I see that the discussion went on. The easiest way to estimate the load is to ignore the ridgeline and look at the angle of the cord, because the effect of...

I'm learning as much from this conversation as anybody so your views are welcome. I don't see htis as an argument.
Anyway, I'm surprised that the 550lbs rated cord would break. Under the conditions...

Engineer, the rating on ropes has a totally different meaning than the rating on most products. If you read rope manufacturers specs they tell you what the test breaking strength of brand new rope...

Couldn't have put it better myself!

The 0.5 factor is multiplied not divided. The tension on the rope is the resultant from the vertical component (weight) and the horizontal component (pulling the trees together). So at 30 deg the...

I would like to clarify that rope is generally rated at the failure load, and recommended for a load 20-25% of that value. Other equipment is generally rated at the maximum working load. The Monster...

Here is my math: Sin of 30 is 0.5, meaning that for a 30 degree angle the vertical component is half of the tension on the rope. Each end carries half of the weight. So for a 200 lb weight, or any...

By my calculation the load on each end rope is about the same as the person's weight. I assume an angle of 30 degrees when loaded, which by my experience requires a pretty tight rope.
The safe load...

Hi!
I saw the threads that mention my product, the Hitchcraft RopeTie, and I would like to address some of the comments.
This product was the result of a couple of years development. The jam cleat...
