…and the only prescription is more cowbell !
Just kidding, it’s more Doortex.
Continued work at the vacant buildings that double as the testing sites at R2T brought us to yet another variation of the Appalachian Doortex. We’re toying with the name Appalachian Slingshot (APS); again with the obvious shoehorning of East Coast stuff in to a rope topic. The APS concept was tested a few years ago when I hooked up and rappelled out of a window on it. The pictures below show us using it in an elevator shaft, but can be used out of a window or even for creating an anchor in a doorway.
The basic configuration for lowering:
This front tie is only needed when the APS is unloaded.
A change of direction was added to the haul line in order to make the hauling easier. We were able to pull down instead of up.
Here it is used to create a strong, simple doorway anchor. The AZTEK is there to pre-load the system.
Also under development is the stand alone use of leg sections sections as anchors in doorways. Here are a couple of pictures of two outer leg sections used to span a doorway and create anchor for the two MPDs used to raise and lower the load. We’ll be taking a serious look at this in the coming year to find out the limits of these leg sections.
