Dangerous, That is one long posting, but very important. You are not in North America I take it. The US doe's have some standards. the plate must show what the capacity of what it is equiped with. As far as complicated to read, I think in the US it's not that difficult to read, the plate shows how much weight can be lifted, at what height, load center,.... the key has and will always be training of the operators (OSHA requirement). I'm not sure what your plates look like, but ask yourself this if an operator can't read the plate do you really want them operating a Large potentially dangerous piece of equipment? not me. I do agree it should be the same across the board to prevent the human factor. Good luck
