Helicopter Tonne Rating Chart ????

[Kulwin Park]

Does anyone know of a chart or diagram that lists the new and old choppers in order of Tonne rating class? Eg: S76 and EC145 into the 4-5 tonne class, and Ec225 and S92 into the 10-11 tonne class?
I'm just wondering what each helicopter landing weight onto platforms or concrete pads is rated to, but don't wish to trawl through manufacturers websites.
Customers sometimes ask me this question for their corporate uses, but I've never had an answer for them.
Cheers, KP :ok:

Do a search for CAP437, Standards for Offshore Helicopter Landing Areas. Chapter 3 has a table which will give you what I think you want.

FAA Helipad Advisory Circular, too ->

Appendix B, page 187

Thanks @HughMartin. The CAP437 was very helpful, though it doesn't include the newer heli's coming onto the market like the AW169, 189, it really provided some great detail.
