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.)
Thanks. I'll dig in deeper, but I can imagine it now. Aren't actuators pretty consistent? In other words, if I use one on each side, then could I count on them to generally move at the same speed and keep it level?
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.
Okay. Thank you for explaining. I'm one of those people who benefits from the extra information.
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.
Yeah, I would say that's true!
