Martin tower packages include a hinge base system which makes installation of your tower simple. After receiving your package via motor freight, the first project is to install the foundation assembly (CHB-13 or CHB-18). The CHB-13/18 is our basic concrete foundation assembly which is used as the footing of the tower. The HB-13/18 is a hinging base assembly attached to the bottom section of the tower that allows the entire tower to be assembled on the ground! Tower erection is as simple as walking the tower into its upright position, and tightening down the bolts on the footing. It's that simple! Once erect, tower plumb is easily fine tuned via leveling bolts on the base. (See Left)
