And you thought going up your mast was scary?
OK, here is another super cool video for your morning entertainment…
While I, like most people, was wowed by the fantastic imagery in that video, I was especially intrigued with how the rigger working up the mast had his safety line secured. You can see what I’m referring to from approx. 0.40 in the clip until 1:07. Curious about the device that he was using to secure himself to the safety line, I sent a message to my sailing and rock-climbing friend Drew, and my arborist buddy Cary. Neither of them were very impressed by how long of a tether that guy was using (if he fell, he would have fallen hard!) but they did both point me in the right direction in terms of what he was using. It turns out the device on the safety line is something like a Petzl ASAP.
As the video below shows, when unloaded, the device slides freely on the safety line. If the primary line should fail causing the person climbing to fall, the sudden load on the backup device would cause it to lock. Cool, eh? By the way, as often as we see people going up the mast, we seldom see people using any kind of backup!
