    I haven't had a problem with suspension failure, not because I am too smart for that to happen, but because so many others have tried, tested and proven suspension perameters that just WORK, and safely. Thanks to all who have contributed to my hanging safety.

    Yeah that's a possibility as well. I think I'll start that thread next. Thanks for the idea.

    OUCH....How did the straps snap? Was it a clean break, any idea as to the cause of the breakage. And a buckle blow out, their has gotta be more to this story. Did the actual buckle break or did the strap slip through somehow?

    Yeah I thought so too. I hear lots of talk about the mathematics of it but was looking for personal experiences. Thanks every one for sharing, hopefully this will help out others and prevent them from thumping on the ground.

    Were there any extenuating circumstances like hanging at less than 30* or juggling in your hammock like Shug?
    I wonder this too....

    How long have you been hanging on your straps and is their any obvious signs of wear, I wonder why one set would snap and the while another holds perfectly well. I am sure their are an infinite number of possibilities.

Snapped at a knot when I dropped into the hammock.

    Knots + geometry + dynamic forces can push the stuff we use into the danger zone.

    This happened before I learned to splice and avoid knots where possible.

    Lesson learned that day...
    Good advice, I prefer anything spliced to anything tied, I am sure knots have their place but I simply do not trust myself to tie them.

Ended up in the truck for the balance of the night. If I had been backpacking on that trip I would have had to do some scrambling to recover as the rain had formed quite a puddle that I went into. Totally soaked,but managed to keep the down mostly dry. It broke under the cover so there was no way to check it ahead of time. Now hang on 7/64 Amsteel whoopies and MSH.
    Glad to hear you had a bail out close by. And this is one reason why I carry an extra dynaglide woopie sling and dutch biner with me on back packing trips. In case either I have a strap or woopie failure I have a back up.

True one minute setup.
    Yeah quality webbing is certainly important. Glad you figured out a safer suspension system.'

    The whipping on the end of the hammock pulled off from the larks head attachment to the whoopie sling.
    No injuries resulted, I was just in the time out chair for a bit

    I also dropped Macentyre 2 times in one night

    He was sleeping in our place, on the way to MN, hanging from straps I had used for years from the ceiling joists.
    First one failed, then a bit later the second failed. Glad I had provided a thick crash mat under the hammock.

    I guess they were not good webbing, something I had found when I first started hanging.
    He made some loops from Mule tape that was hanging on the wall and now I use them instead of unknown strap material
    HUM, yeah if I ever come over for a sleep over TZ Ill bring my own hammock stand

    Now these are the kind of stories that scare me when I am backpacking and hanging. Hope you have made a full recovery.

But the weight of the subject (myself of course) was too much for this wooden toggle. I could not for a minute figure out what had happened there in the dark, inside my HH expedition. Now I use a metal toggle.
    hopefully you were able to enjoy the rest of the trip. Glad to hear you got a metal toggle.

    I still have the knot stashed away on my wall of shame. I'll try to get a pic of it this evening.
    Pictures would be great

    And a big oll +1 on this. Many people deserve thanks and gratitude for helping suspend a community of hikers above ground.
    Sometimes I like to hike and think, And sometimes I just like to hike.

    Hiking is'ent about waiting for the storm to pass its about learning to hike in the rain.

    Very interesting thread, Lazy River you sir add another interesting insight and look into the conundrum.......

    hmmmmmmmmmmmmmmmmm

    Although as much as I would love to add a horror story, I have not yet had the pleasure of having a suspension break on me. Sorry pal!

    I guess I haven't been hanging long enough (3 years) to have a suspension failure. My whoopies used to come off the marlin spike hitch and toggle, which is why I don't use MSH and toggle anymore. Dutch whoopie hooks give me peace of mind, as does splicing. Nice to know a few knots, but I'll go with the manufacturer recommendation that splices retain more breaking strength.

    have yet to have the suspension snap on me thought i have had a toggle fail and it dropped me to within a hairs breath of the floor. carbon fiber toggle from an arrow shaft. was hanging in a friends garage just lounging and someone decided to join me in the hammock. the added weight caused the MSH to crush the toggle.

    I Broke Amsteel 7/64

    I'm pretty heavy--about 370 lbs. I've been dropped in the field twice--both times by situations outside the area of this thread (fisherman's knot slipped, crushed toggle when I used a "found" stick). However, the one time that I straight out broke some Amsteel 7/64 it was in my own home with a new rope. The rope broke right as it entered a knot, and was therefore making a sharp right-angle turn. As best I can calculate, the rope was very close to or even above its rated strength.

    I've had ceiling hooks in the basement for awhile. However, to test out a bridge hammock, I needed to get the attachment points lower. I'd seen a thread where people were making suggestions about hanging a bridge in a small room, and one guy used floor hooks with heavy-duty chains between the ceiling and floor, and then could put the attachment at any height.

    I didn't happen to have any chains, but I did have a spool of Amsteel. So I put a couple of hooks in the wall and tied a couple of loops at eye-level in the near vertical ropes. The bridge hammock then formed an "H" shape along with the two ropes tied wall-to-ceiling. The break occurred on one of the verticals, just above the knot forming the tie-off loop.

    In hind sight, I don't recall worrying too much about the wall hooks, although they were anchored well. After I calculated the forces on each piece of the system, I determined that all the hooks had the better part of a ton applied on them. I no longer use the wall hooks.

    I've estimated the distances and angles involved, and used rough numbers for calculations. The resulting calculations estimate that my Amsteel broke at a couple hundred pounds higher than the rated strength. I think it more likely that the angles were a little less, the hammock a little lower, etc., and that the rope was very close to 1600 lbs.

    By the way, if your wife is in the room above you when you break this stuff, she will be very upset. It literally sounded like a gunshot.

    I haven't had any line snap, and it's interesting because I'm using a 550 cord suspension system, typically the line mostly likely to snap and hence why people are generally steered clear of it for suspension. Maybe I'm just lucky? I expected to see at least one snap in this thread from 550 cord though and there isn't.

    Edit* now I am NOT just using a single piece of 550 cord on each end and calling it good. I took(for each side) two 12 ft pieces, folded them in half, then proceeded to tie knots down the length to act as attachment points for the hammock hook. They have a loop at each end where the two pieces were folded, thus allowing me to use them as tree huggers. Anyone got any ideas as to why this works. Did I essentially make a 2000+ lb breaking strength strap by using two pieces ad folding them in half?

    Not sure how...

    I've never had any of my suspensions fail, amsteel or dynaglide. However, my oldest daughter managed to snap a 1/8″ amsteel whoopie last night, right in the middle of the adjustable loop. The only possibility I can think of is that she pulled the suspension tight to get the hammock up high, and jumped in with considerable force. She's maybe 115 lbs, so I'm not sure how she managed to generate that much force.

    Combining four lengths would add strength but the knots in each will derate that strength. I don't know by how much but in some cordage a knot can decrease the breaking strength by 50% or even more.
