Why in this picture do the towers rise up a lot higher than the terminal? What is the point?

The station's height can be adjusted according to snow conditions!

[Snoqualmie guy]

Is that at all common? I have only heard of it but never seen it.

If it is low does that mean there is heavy snow?

No. It is raised when there becomes too much snow that it would be implausible to simply shovel out the terminal every day. Instead, they simply raise it up.

Many such terminals were manufactured by Yan. The earlier ones, 1976 - 1980, were lifted by hydraulics - later (like in this one) massive screw jacks were used inside each support column.
The scheme was used for both drive and return terminals. Pretty neat arrangement, really.

This is the bottom of chair 23 at Mammoth. We raise or lower it to the correct loading height after a storm. We aslo raise it out of the avalanche path before each storm, it has been hit in the past. There are 4 electric 15 ton chain falls that raise the terminal. The counterweight is remote, about 300 feet behind the lift. This terminal is a drive tension terminal. the terminal can be raised approx. 10 feet and still operate, it has another 6 - 7 feet we can raise it, but non-operational.

Also, does anybody have more photos of the top. I saw it was indoors but if anyone has more could you please post! Thanks!

that must make for a fun day when you have to rase the lift out of the way for avalanche work. but this year you guys had such a bad year it must not had to rise them that much. at alta we raised all of our lifts pretty much to the max. ours are hydraulic, one HS has a pump built into the lift, the other HS's and FG need an pump towed in by a bile.

It is indeed pretty neet. Here's a few:

Does the top also adjust?

[Jonni]

No, the enclosure on this terminal doesn't allow it to be raised or lowered.

[mmsa]

The top terminal does not raise or lower. The big clam shell doors do open and close, but we found out the closing them just trapped more snow inside. There are a couple of hatches in the floor we open before each storm and this helps the snow exit, but we sometimes get a few feet throught the inside. We have to hand shove, where the snow cat can not get to. Windows get blown out from avalanche control, shrapnel from the gun and the concussion from hand charging.

Riblet also built adjustable terminals like that, as did Murray-Latta.

Garaventa CTEC built some detach terminals that adjust vertically as well.

Any photos anyone?

[Peter]

Look in the Mammoth gallery on skilifts.org. Virtually all of their Yan and Doppelmayr lifts are height adjustable.

[skierdude9450]

Not the UNI-G. That makes me wonder, did Doppelmayr make a height-adjustable UNI-G station?

Check the gallery for pics of the tension terminal of King Con at Park City Mountain Resort

That raises up? I don't see how!
