Yes, that's what I mean. (If you dig deep enough in that Bend-Pak website you'll find photos and diagrams of their method.)
It's superior to a winch because getting cable to wind onto a drum is more difficult than it seems. Getting 4 cables to lay down side-by-side is really tough. Running the cable over a simple pulley and down to a counterweight is a good solution to that problem but I don't think you want 4 steel weights hanging above your head.
