Traction Rope Brake . This device is used only on Riblet lifts as far as I know. Its main function is as a low speed back stop or a roll back prevention device. It is used as a zero speed brake as it sets only when the the rope speed approachs zero speed . It was originally operated with a 480vac solenoid but most have been retrofitted with hyd.actuators. ( nothing like having 480 vac right next to the haul rope).the upper jaw relies on gravity and spring bias to bring the jaw down onto the haul (traction) rope and if the rope moves in the reverse rotation the TRB clamps onto the rope much like a klein grip.

You have any left at Snowmass?
I worked on several at Crystal; as I recall they tended to stay clamped on the rope beyond the 'zero-speed' setting. We had one that dragged on the the rope for a while. I don't recall what the lift mechanics did to fix it as it wasn't a lift I usually worked.

I believe the TRB was unique to Riblets, and as such the CPTSB inspectors may only ask that question of areas that still operate Riblets.
I cannot believe they would ask that question during an unannounced inspection of a detachable lift.

It was on the review sheet. I knew what it was. I'm sure they will only ask the dudes that work the High Alpine lift.
