Sterling Bound Loop Prusiks in Rescue Litter Rigging
Hi, I’m Matt Hunt, the Work Market Manager here at Sterling, and we wanted to talk to you a little bit about our Litter Rigging System, which incorporates two pieces, the head end litter spider, and also the bearer tie-in, or the foot end. So what we have rigged up here is developed by Reed Thorne at Ropes That Rescue, and it’s known as the Arizona Tri-Bridle Setup. In the master point up here, we have two of the head end pieces that are running down to the litter rails, and these are seven millimeter sewn cords, 68 inches long, in a Purcell Prusik configuration, which allows them to be adjusted to keep the litter level. At the foot end, we have the bearer tie-in, also known as the foot end spider, which are also seven millimeter sewn loops. These ones are 34 inches, and they’re also used in a pair in a Purcell configuration to allow for adjusting length and angle and they’re joined to this delta link up here.
Now, at the foot end is connected up to the master point with a set-of-fours, like our pocket hauler. Including the set-of-fours in there allows the attendant to easily change the litter from a horizontal to a vertical orientation. You’ll also see an additional set-of-fours, the AZTEK Elite here in the middle of the litter, for an attachment for the litter attendant, which we cover a little bit more over on the AZTEK page. Now, the nice thing about this system is that, for moderate angle operations, you can quickly detach the foot end, leaving the head end attached to the rope system. The attendant can then attach themselves to the litter to help maneuver over rough terrain while being still somewhat controlled and supported by the rope system.
