There's still a triple ferris wheel out there

Hershey's is a double arm that operates like a giant teeter-totter. It also features spinning barrels (a great trick to use 120' up on those with motion sickenss!). Kings Island had a similar model years ago.

The one at PGA is still at the Park in storage! Check out these pics above taken in 2002. The one for sale must be the one from PGA.

SFGAm still has the cages and stuff in the parking lot, even though they scrapped the structure...

I was never on a 3 armed wheel only the double at Hershey.

The 3 armed one has me a bit puzzled on how it ran and loaded. I'm guessing that the arms teetered like Hersheys. How did the third arm load? Once again I'm guessing there were 3 loading time one loads while the other two spin.

One more question. Did each arm go up like the two armed one? For some reason I'm thinking it wouldn't be able to reach the height of a two armed one. Some links to it running would be great!

The PGA Sky Whirl / Triple Wheel is not for sale. It was scrapped in July. Adam is right that the wheel in Kuwait was a double, not a triple. Similarly, Mamoosh is correct that Magic Mountain's was a two-arm model.

For those not familiar with a triple, here is a photo of the world's first, in its first year of operation:
