opnspaces gijoecam - my roof raise has an added length of cable permanently mounted to the roof and the bottom wall to let you know when the the roof is at its maximum height. You can play a pretty good high C note on this cable when the roof is fully up.
After I insert my four lifter arm support pieces in the four corners I do bump the electric switch down a couple of times to lower the roof on top of the arm supports to relieve a little strain. Maybe down to a low C note on the test cable... Its isn't enough slack to allow the cable to walk out of the pulleys... My 12VDC Electric lift system is the Powerwinch Model P55000 Folding Camper Winch. I don't think I have any drawings on the LIFT ARM Assemblies or the wiffle tube showing any pulleys. I'm thinking all of the pulleys on my setup are closed around the top of the pulley to prevent the cable from coming off per say. I know the top of the lifter arm assembly is a closed top on the pulley. I probably should look at this more closly...
Been doing this since 2008 without any problems for what ever that means... I can only remember one time where when lowering the roof that one corner didn't go down all the way. It went down to about 10-inches or so of remaining travel needed to bottom out. That problem was because I was not on level ground.. I moved the trailer a few feet and it came on down just fine...
