In addition, in the area of fastening the lugs the central support unit is formed as a dual closed box profile and to the central and side walls ears with a wall of greater thickness are attached and from the lower end of the thick wall of outer lugs at an angle a curved sheet sidewall is upwardly mounted, which forms the box-shaped profile with low sidewalls, and on the upper belt of the central support unit a C-shaped curved belt is installed, which forms a segment section and holds outer ears with a central ear.
