It seems that some builders have no foresight. For at least the second time in as many months, somebody has crashed through their porch flooring and into a well. This time it was under an overhang, so no aerial was able to be used…. and it was a 60 foot drop. This rope rescue occurred in Hendersonville, NC.

I imagine that these guys had the same problem as the guys doing a well rescue that we talked about a couple of weeks ago: the tripod is going to want to tip towards the direction of haul because of the resultant force being outside of the tripod footprint. Just looking at the pictures, it might have been possible to use the bottom of the porch column for a change of direction down low to help minimize that.
Also take note of the VERY long bights an the end line figure 8 knots. Those are going to eat up a lot of valuable real estate when trying to get in and out of the hole. The knot passing pulley is also going to eat up quite a bit of that same space. By tightening the bights and using a smaller pulley, it is possible to gain several inches of extra clearance where it is needed most.
Rig Tight!
