What's the VR-104. I haven't seen that one or know what type of lift it's used on.

I know, this subject is quite an old one, but I'd like to tell you something about these grips because I know how they work ;).
1. You made a little mistake. The VR-101 grips look like that:

...and here.
Normally, the spring provides the force to get the rope connected to the cabin. If it fails, the weight of the cabin will activate a rather complicated system, the force will from then on be provided by the gravity, i.e. the cabin's or chair's weight.
2. Following the VR-104 grip:
Click here.
It just uses gravity. The problem is that it may detach if there are shockwaves throughout the line... There's only one gondola left using this system. I've made some pictures of it, if somebody is interested in that.
All the pictures you have posted are VR-105, even if they look different. They're similar in the way they operate, just their design is differing a bit (the design depends on whether it's a gondola grip, a quad grip and so on). Unfortunately, I can't find any picture that describes its function clearly... I'll keep on looking for one.
VR-105 "knows" two positions - open or closed. One jaw is connected to the wheels that roll on the rail - it's moveable. The cabin is connected with those wheels. There is also a fixed jaw (the one towards the inside of the line), it is connected with the little wheels. Those are connected with a spring that makes it possible for the jaws to be moved (if there were only fixed fulcrums, the grip wouldn't work, but like that, one fulcrum is moveable and the grip can be detached). Furthermore, the spring makes it possible that the grip stays open when it's in the station. The grip is activated when there is a pressure on the little wheels.
Sounds very complicated, but is actually not that weird. I'll keep on looking for a better description. The best way to understand its function is to watch it operating...

I finally understand how they work after seeing/riding the Keystone Gondola. It is somewhat complicated. The best way is to see it work. So, if I go to Keystone this weekend, I'll get a clip of it working.
Basically, as it enters the top station, it goes over sheaves in the outside rail. It drops down about 8 inches or so which opens the grip using the stablizing rail.

the vr 101 grips are a gravity type grip.or known as a box grip.some vonroll type 101s are still in existance.all are found at amusement parks.san diego zoo, seaworld san diego,cedar point ohio,tulsa state fair,bronx zoo new york,great america santa clara california and many others..
Was there a VR-102 ever made? I heard they were developing it to replace the VR-101?

In Europe there are a lot uf gondolas with a VR-102. Doppelmayr also used this grip for his gondolas.
In Switzerland there are still 3 gondolas with VR102 grips.
- Saas Fee
- Wangs
- Chur (an old rebuildet gondola form Flims)
