I keep my "go bag" in my truck in case I need to do some impromptu climbing, but it's also my heavy lift
bag, used for raising and lowering tower sections and large antennas. It originally was a "self-rescue" kit,
the kind OSAH might require you to have at a work site. I cut off and threw away the "auto-ascender" it came
with, but kept the rope (DBI/SALA, although I assume it's manufactured by Sterling or some other name brand)
and all the accessories it came with.
I really only bought the bag for the rope, so I was pleasantly surprised to find it came with some extra
goodies inside. These included a 6ft heavy strap, a fall-arrest strap, a high visibility vest, and to my
surprise, a nice adjustable harness with good carabiner. The harness didn't have positioning straps so I
added two short climbing straps.
I added a steel ladder hook to the end of the rope, and threw in a heavy pulley with chain for the tower base,
as well as a heavy pulley for the tower. These are #50 stainless pulleys, with built-in swivels, a working
load limit (WLL) of 880 LBS.
Finally, I tossed in a basic rope and climbing equipment bag and a "mechanical advantage" pulley kit, that
gives me 5x advantage to move just about anything by hand, great for emergencies.
