Where do you measure hooks to find their strength? What is the calculations to determine their strength. Is their any equations to finding hook strengths? Need to know because my body wants to use these iffy hooks to move these big airconditioning units to a roof on his factory with a massive overhead crane.

Listen to MSM!!!!! If you are not 100% sure of the WLL (working load limit) of the rigging you are using you can not use it!!! No tag No use. A couple of hundred on some new rigging is well worth the price when you consider the cost of wreacking the crane, dropping the unit, or, God forbid, killing someone. I have had many, many, hours of OSHA training for my job. Rigging is what I do a lot of at work, and let me tell you, if we get a brand new $2000 set of spreader chains on the job for one of our cranes and there is no tag on them, even if they are brand new out of the box, we send em right back to the manufacturer to be re-tested and tagged. The liability is just too much to ignore.

Look for the Safe Working Load (SWL) cast into the side.
Also should have the safety snap in place and working.
Look for signs of the hook opening up. There is a measurement that could be taken. If it has opened up any thing over a certain value then throw the hook away.
The hook is meant to be the week link in the system. Meaning that if the hoist and cable and all other things have a safe working load of lets say 10t, then the hook has a SWL of 8t (these numbers are likely wrong).
It is done that way so the operator can see the weak link and be able to check it easily each day. If the hook has opened up then you know the machine has lifted a very heavy load and everything is suspect and has to be checked.

If you are lifting anything commercially, any of the cables,chains,slings etc have to have a weight rating on them,either cast in the hook,or with a metal tag on the chain or sling,or a label on the strap.No tag,or label=no lift.
If they drop the a/c unit due to a hook breaking,quess who they are going to come hunting,probably with a slew of lawyers and a few OSHA inspectors thrown in for good measure?

I think the rating is molded into the side of the hook.
