Yeah. Let me dig back through the "archives" of pictures, and I'll try to post a pic or two for you.
Little "teaser" pic of the mechanism/terminal design:
New LPA grip (there are two grips on the rail, one in the foreground, and a smaller version in the background):

I'll see what I can put together. I might have a few different angles of the grip. That "guy" is Tom Clink, our tour guide. He's the sales manager, but spent years running the lift department at Breck. Knows his stuff about lifts.
I don't really think that the new LPA grip is "better," per se. It's just different. I guess the Italians (I believe Leitner wanted this new design, IIRC) don't like ball joints, so they didn't like the eccentric spring packs of the Omega grip. L-POA wants to use the Omega grip as long as possible. Not sure how soon we'll see the new grip on US installations.
This is really all I have:
Whole "demo" unit:
LPA grip jaw:
LPA grip from the other side (good look at the traction plate):

The impression I got was that it will be soon. But I don't really know how soon. The ones they were constructing the two times I was at the factory were Omegas. Maybe next summer's installs?

Yep. Fun place to visit.

Doppelmayr uses a Pilz PLC to monitor everything. With clocked outputs feeding various sensors and monitored outputs, it can be VERY difficult to jump out a fault. Grip force is monitored by a deflection prox that is susceptible to static discharge between the haul rope and the grip.
Poma uses an Allen Bradley PLC to monitor everything. Every normal stop can be jumped out via a touch screen and a "Safeties Bypass" switch. Some E-Stops can be jumped out with a switch, touch screen, and "Safeties Bypass". Grip force is measured by a mechanical switch (Go, No Go).
As long as protocalls are followed, it is TONS easier to jump out faults on a Poma and clear the line if need be.

Poma Safety Bypasses can be a pain IN THE ASS to set a bypass.... ;). Since I have been a Drive Operator on both Poma and Doppelmaryr I'm going to say that I like the Poma's better. @ least the new ones. Have not ran an old Poma yet. But that time is coming in the next few weeks.

OK Kicking Horse - how is bypassing a Poma Safety Bypasses a pain in the A$$?

Weren't these grips supposed to come into the U.S.A in 2007? The thread in the images forum for the Highline Express and Sourdough Express lifts at Vail says those two lifts were supposed to use this grip but for some reason got the classic T-Grip they've been cranking for ten years.
