Good find Mick!
Alex seems an honest bloke to post up a mistake like that.
I too have had a few arguments with CO's that didn't end well, rookie CO's both times.

Interesting fall testing results here by DMM using Dyneema and Nylon loops guys.

Take a 3-4 ton pick with it before determining how much faster than a standard clevis n choker it is Kev.
Your own links state one of the cons is getting them undone after lifting a serious load.
Jomo
Yes Mick, exactly.
Show me a crane anywhere that doesn't have any clevises on board?
Weight and sleekness are your friends spooling down through lotsa branches n stuff IME.
Straight n narrow yu know?
Jomo
I'd delete the vid because it's disingenuous, outrageously so.
Who the fug takes takes the choker off the hook each pick anyway? Only a complete idiot who has no idea what a clevis is.
It's a BS sales technique IMO.
Jomo
We're talkin tree biz guys, not general construction.
Why do you think the vast majority of crane rental companies won't rent to tree services?
What is it about this industry that causes them to freak out?
Jomo
Who said anything about replacing the crane ball?
The manufacturer's hook sucks for this industry, not the ball itself.
All it takes to get into trouble is the rigging being on one side of a big lateral branch, and the ball n hook on the other side for goodness sakes!
Have you got X ray...
Well you certainly had no hesitation bout tellin Paul to shun a crane hook that's fool proof for this industry.
Pretty bold advice for someone who has never taken down any trees with a crane mate.
Jomo
Yeah, well in the real world CO's often work in situations where they rely on spotters to relay signals to them, creating lag time as to when they stop spooling down n stuff.

Think of it as yarding with a crane Cory.
Yes the average daily count was about 60 trees a day on the Murphy Canyon contract.
One of the most lucrative contracts Atlas Environmental Services ever landed.
The whole crew was making double wages. My best year for sure at 110K.
Jomo
When you work with an in house crane for a decade doing nothing but removals every day, it adds up quickly.
Just one naval housing removal contract in Murphy Canyon totaled 4K trees in just under 4 months time.
In truth my total's well over 10K crane assisted removals.
Jomo
As long as the latch can support the weight of the ball you're good to go Paul.
The Crosby Shur Loc's the only crane hook I know of designed to do just that.
Jomo
I've done many thousands of crane removals and learned that Murphy's law applies.
That knot's eventually gonna get hung up in a tight crotch, and unless the CO's really observant and on his toes?
It's going to end up supporting the entire weight of the crane ball, with a 50/50 chance that...
