This is a User Failure that resulted in equipment abuse.
Hammock load was 250-300 lbs.
When using Cinch Buckles, proper attachment to the hammock via chainlinks is important.
Multiple wraps for the larkshead, or even better multiple wraps for a spliced continuous loop, keep the buckle properly oriented/aligned with the strap.
Strap alignment allows the cinch buckle to do it's job.
Even a 4400lb rated cinch buckle won't help you if the straps are not properly aligned.
Improper setup may lead to failure, i.e., terra firma gluteus maximus impactus majoris. plainly put, butt on the ground.
This morning I witnessed this failure first hand when a guest hit the dirt with a laugh. Nothing injured, all is well, this time. There were multiple failures in process, vigilance, implementation and decision making.
But the failure to inspect the equipment after the last couple hangs prevented observing the warning signs on the strap and when finally observed, no corrective action was taken.
Choosing to stick with chain links that were too short to allow multiple wraps for the larkshead because they were Pink, like the hammock, bad choice. (Now she is ok with using the Orange 1/8" amsteel)
Thinking that manually orienting the cinch buckles would be sufficient instead of using the multiple wraps on the (again the Pink thing) cinch buckle/continuous loop.
The bottom line is, without the extra wraps on the buckle, it can and likely will twist and drop the single larkshead into a corner of the buckle. This twists the strap which moves the slide in the buckle and you no longer have the locking friction of strap on strap to hold the slide or strap in place.
RESOLUTION
I have swapped her 1500lb straps out for 3000lns.
Removed the Pink continuous loops and buckles.
Spliced on some 1/8" continuous loops with multiple wraps on to the buckles and reinstalled.
Larkshead slips to corner
Slide is moved and is not locking strap in place.
Example of replacement cinch buckle/ continuous loop setup.
