# Thread: Single Line Suspension (SLS)

1. Welcome aboard jersey. I've been here over 2 years and still feel like a newbie at times. The buried loop was something I thought was new until it was pointed out that it was just a UCR. Working with some aging mental capacity here but visualizing the loop with constrictor around the SLS sounds great. My loops are fixed since I use the same hammock and don't need to adjust. I have found on my present hang, every night for 1 1/2 months, that the only 2 trees close to the RV are at my maximum span with the SLS and short of a step ladder I can't get the huggers high enough up the tree to keep my butt off the ground unless I sacrifice sag. My only option is to remove the buried loops and reposition to affect the sag. With your loops around the SLS adjustment would be simple. Thankfully my system is in constant flux and subject to be altered at any time. Will be looking at incorporating some of your idea.

Thanks for joining in with your ideas. This is what keeps the forum alive and growing.

2. ## forces?!?!?

I'm new here and happen to be a rock climber from years past. I'm intruiged by the simplicity of these setups but worry about the forces involved. Anybody care to straighten me out on this? The following video is for reference.

I don't know what algorithm was used to create this calculator but it cannot account for the differences in angles created by the structural ridge line nor the distribution of loads through the multiple points of the hammock itself, which contains curves: http://theultimatehang.com/hammock-hang-calculator/ It is probably a simple three-point vector description as you demonstrated in the video and would thus be conservative, which is good.

It's a certainty, though, that in hanging a hammock the forces are multiplied at angles shallower than about 30* -- one can feel the structural ridge line begin to tighten at that point, which means it is taking up load or "working" in terms of physics. So, a SLS forsakes fiddling with angles, assumes the line will bear the whole load, and overcomes forces by the brute strength of the line.

The distance between trees, their size, and placement are the greatest variables in the woods; so, suspension is the greatest challenge, especially if one is trying to achieve an UL pack weight.

In another thread fallkniven spoke of using prussics for a gear hammock.

This has caused me to re-think the SLS ... once again!

great video dude. thanks for sharing
makes sense
