I would look carefully at the construction. There are no doubt some bolts (possibly even those in one of your pictures above) holding the sections together.
I would be surprised if Gorilla wouldn’t give some guidance over the phone.
If you try to disassemble anything, make sure to take pictures of everything before you start taking it apart, and of each step along the way. I do this all the time with machinery to make sure I can put things back together.
