how to keep a knot from tightening too much when lifting something

[lamanated]

wondering after prying for a half hr, if there is a way to tie a knot or keep a knot from tightening up so bad you cant get apart when you are lifting something,, We are using 2"straps..

Have you tried a bowline?

Put a piece of 1" PVC conduit in the center of the knot. It won't crush and will slide out reasonably easily. Then the knot will loosen up somewhat easy.

Use a bowline knot

The running bowline has the anti-tighten quality of the bowline plus it will tighten up on whatever you tie it around.

Knotting straps is really a no-no and doing so significantly reduces the lifting capacity of the strap, as far as I know.

That being said, you might try half hitches like shown in the above image, or a variation such as a cow hitch.

This knot slips and becomes a choker though. Perhaps this would not work for your application.

They are usually pretty easy to take apart after use though...

If the strap won't allow using a bowline, try a "sheet bend" knot. The knot is used to tie large tow ropes together on ships and comes apart easily.

I did not notice the intent to tie knots in a strap. I've never done that, it is a real bad idea. Get a rope and use rope knots. Or use a strap and slings as they are meant to be used. Or a chain.
