Pierce doesn't advertise the Sky-Arm on their site any longer.
The 250 tip load is probably fine for departments that primarily use ladders in a vertical arena more than horizontal. Longer setbacks, where the ladder is more "horizontal" are where you need the higher tip load. If you are more vertical on the ladder, you can load the tip heavier. Larger cities where they're climbing to a tall building (Chicago, FDNY) can use a medium duty aerial given the way they operate.
As an example our aerial has a 500 pound tip load at maximum horizontal extension and 0 degrees of elevation, and that load increases the farther you go vertical.
I can't find a good photo of an aerial chart to show you, I'll keep looking.
