Hello from a non-engineer. This post has a very practical purpose: I'm about to move into a small loft apartment with high ceilings but limited living and closet space. I'd like to find some way to mount a pipe to the ceiling via pulleys and rope or cable that can be lowered and raised with a hand crank. My dilemma is how to keep the pipe level, since I'd like to use only one hand crank. I've looked at a setup something like this (a repurposed bike rack), but I can only imagine that it could be difficult to keep a heavy rack of clothes level while raising and lowering it. Any suggestions? (Thanks for the help).
