       | ok so like the lid moves up and down on those? How does it seal?
       | How does it keep from tipping sideways or jamming on the walls?
       | fascinating

         | TL:DR yes there is a seal along the roof edge and alignment
         | poles/rods so things stay flat.
         | 
         | I do fire suppression builds for these tanks, so all of my
         | equipment on the tank lid has to move up and down with it as it
         | gets filled/emptied. So we end up with self coiling
         | cables/hoses that have to collect themselves on the lid as it
         | fills up. Linear heat detection wire goes all the way around
         | the rim of the tank and also along the lid, which melts and
         | signals the alarm/suppression system in the event of a fire.
         | Companies with more money also have us install UV/IR based
         | flame detection.
         | 
         | Same with these usually having a ladder that becomes more or
         | less stairs depending on how full the tank is.

       | right might still be an improvement from where you are, I
       | suppose.
