I finally saw a rope gripper fail in a way the manual never covered
Last week in a high rise downtown, a 15 year old unit had its safety gear trip during a test. The rope gripper held, but the steel rope jumped and got a nasty kink about three inches from the jaw. It didn't slip, but the rope was totally wrecked. The manual only talks about slippage, not this kind of damage from a bad jump. Has anyone else seen a gripper hold but still trash the rope?

Always figured a held gripper meant a safe rope, but that's a scary new failure mode.

The real problem is when a gripper gets worn down in one spot but looks fine from the top. Saw a rope where the core was totally chewed up under the sheath from being held in the same position on a fixed line for months. The sheath hid the damage until it was too late. Makes you rethink checking gear just by looking at it.

That point about the sheath hiding the damage is exactly right, @nguyen.tara. I had a similar scare with an old rope that felt stiff in one short section. I started pinching and bending it along the whole length, and you could feel a flat, crunchy spot where the core was gone even though the outside looked okay. Now I make a habit of running the rope through my hands like that, feeling for any change in texture or diameter. It takes a bit more time than just a visual check, but it catches what your eyes might miss.
