Sometimes you take the grip apart and inspect it under blacklight. Sometimes the problem is obvious...

This is from a Yan Type 3 grip, such as R and S lifts or Four Points at Steamboat.

I don't know which lift that's from, or if it was found 'in service' or on the shelf after being dropped. Nonetheless- :shutup:

No-one would have died, if that's what you're thinking. Notice the crack is only on the 'ear' of the jaw; the meat of the jaw would have remained to provide grip force on the rope. It's just that the crack is very big... This is why we inspect grips.

Yup, and turn the dead jaw into a nifty paperweight. You can actually just change out the mobile jaw (the broken part seen here) on these grips without having to change the entire grip, but we have around 70 spares left from Triple-E lift to use, so we just put those on lock, stock, and barrel.

In the spirit of Mel Brooks I see. :D
So how old was that grip anyway and how long do those grips ussually last?

No - cracks of that severity don't happen very often at all. Grips can last 20/30 years if properly maintained. The grips on our T-Bar were 32 before they started to need replacement.

I wouldn't want to ride on a chair with a 3 inch craching going down the middle of the grip! :help:

That grip was either an '82, '83, or '84, depending upon whether it came from R, S, or triple-E. So it's barely twenty years old, but that could have been a freak crack.
You wouldn't ever ride a lift with a cracked grip- that's why we do summer maintenance.
