Two different years, two different derails... the third is what we did to keep that damn rope in the grooves! As for rope damage, all I've seen is some slight abrasion on both the rope and the catcher.
The T-Bar is open now... expect some derail pics sometime soon :)
Sorry the pics are so small, but I can't upload large files.

K...the rope catchers don't stop the lift, the brakes at the drive terminal do. Many different variables come into play on how a cable could sustain damage such as broken wires. The speed of the lift, loaded carriers, the surface condition of the rope catchers themselves. It's very hard to say especially from in-experience how a cable would not sustain "much damage" in the event of a deropement.

That would be interesting.

I know the catchers don't. I meant the sensors/forks. I see how it would affect it if the lift was moving quickly and loaded heavily.

generally speaking, haul rope material seems to have a nice combinaton of flexibility and wear resistance, coupled with great strength. i've seen ropes saw into a cable catcher, saw into a grip body (fixed grip hung up and slipped on the rope), and destroy a grip/sheave train (detach grip hung up but wouldn't let go). on the other hand, too many chairs taken off in a row for annual NDT lead to an ever-so-soft derailment as the rope got light.
a lift manufacturer once showed me a video of what happens when a lead-in sheave side-plate falls off and the rope derails to the outside, HSQ at 1000fpm. ugly indeed.
as previously said, lotsa variables, lotsa results.

It looks like that metal got a little hot by its color.
