Why?

The angle β = 50° between the sling leg (cięgno zawiesia) and the vertical exceeds 45°, so the range up to 60° applies, with a limit of 6000 kg. You cannot choose 9000 kg simply because 50° is close to 45°. Use the rating for the whole range on the sling tag without calculating an intermediate value.
