Well, we were almost done today. The problem we now have is that the "winch" only "detents" and "locks in place" in one-direction, on the way up! The operator would have to lower the chassis very carefully as the load of the chassis is continuosly felt at the "crank-lever" as it is lowered. We will be testing a "worm-drive type winch" as they are much safer and easier to use. Stay tuned...
