I don't know whether you have already heard about it, but in Spain, there is AFAIK a high-speed quad using the old grips with marhsmallow springs. As I was told so, I was amazed and couldn't believe it at first. But it seems to be true :).

The chairs were manufactured by another company, I think.

Pictures can be found here.

Interesting, I did hear a few went to Japan, but not Spain.

Welcome to the forums.

Thanks for giving a pictures link! I've never seen one of those grips. That marshmallow spring is surprisingly small.

It doesn't seem like it would provide much gripping force.

I see why it failed......

the yan 7 rubber marshmellow springs, number 0337, were manufacturered by firestone. currently out of production i think but provided a lot of clamping force, in the hundreds of pounds when compressed. and there were 2 marshmellows - each acting independantly.

The chairs were made by Gimar Montaz Mautino, a french manufacturer.

Actually, the marshmellow springs were okay. The problem was really the grip itself... how it worked and such.

[skier2]

Yea, but when it got colder the rubber became more brittle and susceptible to being unreliable, among other factors, such as the actual grips cracking and just being badly designed in general. I could go on for hours, but this topic has been exhausted.

Why do they have the fork in the grip?

[shoemanII]

you mean the flat, forked needle (on top)?

[skierdude9450]

Yes, that's what I mean.

The fork acts like a finger on the grip. To raise up the hold down sheaves and to smooth out the ride. The marshmellow spring was replaced with a coil spring the last year or two before we had to replace the lift.
