If we’re using Petzl IDs, or we’re using MPDs, what we can do is we can make a three-to-one haul system on either one or both of them, lift our victim up just enough to get him off, disconnect, switch back over to our lower and lower him down to the ground. When he does make those connections, when he comes back down, there’s three different ways that we can lift that victim up. The ground’s going to take up tension on our victim, and then our rescuer is able to disconnect whatever our victim’s hanging off of and to bring him down to the ground.
Then, the ground’s going to take up tension. He’s going to sit back, communicate with the ground. Once he makes his connections to the sternal D-ring, he’s in a work position, and then he’s good to go. The way he’s positioned right now, he’s going to connect both into a sternal D-ring. He only has a sternal or a dorsal D-ring. On this one again, he has a tower harness on. Two anchor slings, then he’s going to go back down, and he’s going to make his connection point to our victim. He’s going to make his connection points around six feet at least above our victim. It’s kind of the sweet zone up top above our victim.īoth are going to be at the exact same spot, twin-tensioned again, they’re both going to be, trying to mirror each other, if you will, up top and on the ground. When he’s making his anchors up top, he’s trying to get to that 6′ – 10′ range. Once he assesses the victim, he goes past him.
He is bite carrying both of his ropes, his main and his belay, up to the top above our victim, once again, maintaining 100% fall protection using Y lanyards and his work positioner as he gets to up top.Īs he bypasses the victim, once again, he is assessing the victim as he goes, seeing what exactly is wrong with him, checking his harness before we make any connections to it, before we actually put any pressure on it to lower him down to the ground. In our skate block system what we’re using is we’re doing it with one person trying to be as clean and efficient as possible with a small group of highly trained individuals. There could be many scenarios that we could use this operation for. He’s either fallen on his fall arrest device or sitting in his work positioning device, unable to get out of it, and he’s unable to get down to the ground. We have a victim up top, once again, he is a compliant climber. All right, this is the rescue scenario we’re doing right now is called a twin-tension skate block.
