In a very fun shoot, we met up with Rich Hattier of ISC.  Rich is not just one of the best technical riggers I have met, but one super nice guy as well.  Our shoot was scheduled to discussed the upward and downward mobility of arborists, but also look into the transitory elements of what industrial access athletes can pull from the arbor professional athletes. What we found is that both industries pull from each other and may actually not even know it.

In standard rope access system, a two rope system is always used.  Both are on known anchors.  The ascent and descent modes are not in question, however if in the case of a problem with the mainline, the technician must first rely on first, the back up systems, and then… move to a change over self-rescue mode of ascent or descent.

In the case of the a 2 rope or twin rope system, the climber or technician is always on primary ropes…. There isn’t a designated main/belay or main/safety line as they are both “main” or primary.  There is no backup.  So.. if something were to happen with one, the mirrored system continues to progress on… whether ascend or descend.


And what about rescue?  We’ll get into this in another video.

We’ll talk about pros and cons in our video below.
