You use the mainsheet to raise or lower the mast. Some people have modified things to use an electric winch.
The mast struts
The system with gin pole
Looking at your engineering drawings; this is a Hunter designed system? Was the entire system sold by Hunter? Do the struts need to dynamically lengthen as they travel the raising arc? How heavy is your mast? Perhaps my 140 lbs isn't heavy for a 33' mast, but it was beefier than I expected when first lifting. Do you have any photos available of your install?
