Q: What makes a one pulley more efficient than another? There are a couple of key factors that affect the efficiency of a rescue pulley. The diameter of the sheave (the wheel in a pulley system that supports the rope) can make a difference – the smaller the diameter, the more bending of the fibers …

So lately, I have been going through a type of transformation of sorts. I will be honest… not all of the process has been fun and pushing through bias demons can be difficult, but with friends like Craig McClure, Jason Ilowite and Rich Delaney… the sojourn has been rewarding. Bear in mind that a sojourn …
