What would happen to the operators of that crane if they went over rated load ? Even though they knew the posted load rating...know the answer and rhetorically asking for the group
First career was in industrial motor controls and one market sector was cranes (material handling). Circa late 60's to mid 80's
Know they had engraved metal ratings labels riveted to the crane, operators cab and on the pendent controller
Our computers would have recorded, sounded an alarm at each overload attempt and refused to move after a preset number of trys. Some required a keyed reset after reaching those numbers of trys...this is why said pretty soon, OEMs will control more to all ratings like they now do with ICE rev limiters
Nuclear and military had more onerous notifications and margins vs civilian of the exact same mechanicals...though they often had locational requirement in the +/- 0.03 inch at some tonnage, which had additional mechanicals, etc
Prefer stout's or porter's

Tire ratings / axle ratings are just like Over Head Crane ratings..
They are rated to a certain rating with a safety factor on top of that.. They POST the rate based on every day usage.. Most people will see that they can carry XXX amount of weight and go full Hog till they cant..
I can assure you, If they rated our overhead cranes to 15 ton instead of 10 ton, we would be lifting 15T every day, all day... in a nut shell - There is a safety factor built into EVERYTHING with a MAX capacity.. just how much = ??
