doppelmayr vs poma

I think there was some speculation about them being introduced last season. However, I guess the Omega-T just made more sense. You know I just realized that this is the 15th season of the Doppelmayr DT series grip, and it's still going strong.

15, wow! 
Last summer was the 15th summer of DT-104 lifts, or, this summer will be the fifteenth summer of construction for DT-104 lifts. I still would think that the latter is more likely, as Timberline Express at Copper was built in 1994 yet is DS-104 grips.
It's no wonder the standard Dopplemayr CTEC build is Dopplemayr terminals and towers, DT-104 grips, and Garaventa CTEC chairs. Unless you go to Beaver Creek's Dopplemayr CTECs, which use the Garaventa CTEC AK-460 grips, but everything else is Dopplemayr. All four of their Dopplemayr CTEC high speed quads are like that, with Dopplemayr chairs, towers, terminals, and sheaves, and Garaventa CTEC AK-460s. Then, Raven Express at Wolf Creek (the only Dopplemayr CTEC high speed quad in Colorado not at Beaver Creek) uses the DT-104 and Dopplemayr chairs, while then there comes the Beaver Creek Gondolas, which like the high speed quads when they were built, have Dopplemayr towers, sheaves, terminals, and cabins, but Garaventa CTEC AK-460 grips.
I still wonder why the DS-104 lasted ten years and then was replaced, yet DS-104s have the most variety of terminal styles ever found?

OK Kicking Horse - how is bypassing a Poma Safety Bypasses a pain in the A$$?
Because whenever a fault needs to be bypassed they have to do it 3 or 4 times. Maybe it's a bug in the software on the VX.

It should be straight forward enough - Touch the "Faults Bypass" button, enter the password, touch the "Enter Fault Number" button, enter the fault number, turn the "Safeties
Bypass" on, and start the lift. Also manually monitor the system that is bypassed and log with dispatch.

That's how it's done. But they have to do it 3 or 4 times. I think it's a bug in the current software.

The DT-104 grips were first introduced in Austria in 1993. They first came to America in 1995. None of the lifts at Beaver Creek use the Garaventa AK-460. They use the Agamatic A-104C, which was from an Italian company, and the gondolas use the A-108C, or the slightly larger version. DS-104 grips were only found in two series of lifts; the CLD-260, and the UNI. (And I guess the Doppelcake at Panorama if you count that.)

The DT-104 was are still offered because they're less prone to rime issues.

I assume you mean the chain conveyor stations when you refer to the CLD260 ? CLD=chair lift detachable, 260=gearbox size. My DS104's are in ET stations (second generation 1989,1990, 4CLD-ET235) I am not sure UNI stations are anything but DT's (mine is)

really! I did not know that. If it has a traction plate rime is an issue .

The Agamatics have a second issue with rime (after the usual problems with traction plates). The traction between the rope and the PTO sheaves required to open the grip before coupling sometimes can't be achieved when the rope is too icy.

The UNI station was not just one station, it's an entire series offered by Doppelmayr. The four main types are the first series UNI (1989-1994), the second series UNI (1995-2002), UNI-G, and UNI-GS. Out of all of those, the first series UNIs and some of the early second series UNIs used the DS grip. Anything afterward either used the DT grip or the Agamatic grip (in later years).

Here's what I know
The basic design of both brands are the same.
The Poma tensioning system on detachables has both terminals on rollers that are moved by hydraulic rams. The Doppelmayr detachables only have tensioning in one station and the hydraulics only move the bullwheel. The bullwheels on Doppelmayrs also are slanted, not parallel with the ground.
Doppelmayr detachables can run in reverse and have chair parking in the terminals, Pomas do not do either.
The construction seems different, too. Poma terminals come largely pre-assembled from the factory and Doppelmayrs seem to be assebled more on site.
As for the fixed grips, they are pretty similar. Poma uses the Alpha model drive/tension terminal on all their lifts, while Doppelmayr has a variety of different drive and tension configurations.
That's what I can think of for now...

Skier, The American Flyer Poma Det. Quad has terminal chair parking at Copper Mtn.

Really? I wasn't aware of that. I'll have to go looking for it tomorrow.
Skier-- older Pomas also have carriage-only tensioning, and the carriage rails are inclined as well.
