The above 2 posts is what I was getting at. Ignoring legalities, liabilities, etc, what safety factor is engineered the truck before you start breaking stuff.
I have been told (correctly or not, maybe crane op can help) that lifting chains/slings have a capacity double of the WLL (working load limit)?
I didn't know if that same sort of capacity was engineered into trucks.
I realise now that there is no simple answer.
Lifting hardware is rated at a working load limit of 1/5 of test data.(breaking strength) If it has been exceeded at any time that rigging is no longer to be used by the the rule.
