Does the use of a TCK coupling pin maintain the manufacturers "load rating" integrity of the tow coupling?

Yes. All tow couplings sold are allocated a Component Registration Number (CRN) by the Australian Federal Office of Road Safety (FORS). At that point FORS allocates a "load rating" for that component, an upper limit of operation.

It follows therefore that in order to protect the manufacturer and communities expectations with regard to safety and performance, the coupling repairer and users should demand certified components of the highest quality for repair, capable of meeting those needs and returning that coupling back into service capable of operating safely at its maximum load. TCK's pins are certified to meet those needs. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
