I'm not sure of what you are trying to control. A brief description would be nice.
However, I can comment on a couple of things:
1. Use meaningful-as-possible name for your symbols. left hand and right hand doesn't tell me much. If it is limit then say "left-side limit". But then you get into the problem where it all depends on what side of the machine you are standing on. For example, north door down limit switch is much more descriptive.
2. Rung comments are a good thing. Not only do they help others troubleshoot, they also help you.
3. Speaking of limits, motors, and rams. If you ever design something. Make a print showing the location of all these items. This becomes a real issue when you got dozens or hundreds of items on a machine. I've wasted a lot of time just trying to find the limit that I know is bad.
4. Too much documentation is never enough.
