    Auto Load Release
AI Thread Summary
A user seeks a clip that automatically releases under a load of approximately 250lbs, ideally adjustable between 200lbs and 300lbs. They are exploring options like shear pins and torsion springs but are unsure if a suitable product already exists. A referenced product from SkySki offers an adjustable release from 100 to 800 pounds, though concerns about its cost and accuracy are raised. The discussion highlights the need for an effective, affordable solution for automatic load release mechanisms. Input from engineers or product designers is requested to find a viable option.

Looking for a clip that will release under a load of ~250lbs.
Been looking at shear pins and torsion springs but wondering if something already exists.
It will be used between two ropes and will release automatically once load is hit. Something adjustable from 200lbs. to 300lbs.
would be ideal.

Any engineers out there have any ideas?
Thanks in advance

They say it's adjustable from 100 to 800 pounds. Not sure of the resolution and guaranteed accuracy,

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
