      In the following slides, the special towers with installation for public use are illustrated.  It will be noted that each tower head has its own distinctive appearance - in spite of the fact that the function is more or less the same in each case.

 

H84.  Overall view.

TELECOMMUNICATION TOWER AT HAMBURG
(HEINRICH HERTZ TOWER)
(1964-68)

H85.  Overall view.

  • Total height 271.5 meters, height of towerhead for public use 119 to 134 meters, and of towerhead for the Post 143.5 to 159 meters, height of concrete tower 204.7 meters.
  • Tower diameter 16.5 meters at foundation and 6 meters at top, wall thickness 0.9 meters at foundation and 0.3 meters at top.  Foundation on a conical shell, maximum diameter 41.0 meters, at 13.6 meters depth.
  • Towerhead for public use with lookout platform and revolving restaurant, maximum diameter 32.4 meters; towerhead for communications with three stories and a maximum diameter of 39.8 meters.  Six antenna platforms.  Supporting structure for towerheads and antenna platforms consists of conical shells (see also Slide H92).

TELECOMMUNICATION TOWER AT MANNHEIM
(1972-75)

H86.  Overall view.

  • Total height 204 meters, height of towerhead 121 to 137.5 meters, height of concrete tower 166 meters.
  • Tower diameter 13.3 meters at foundation and 4.6 meters at top, wall thickness 0.6 meters at foundation and 0.3 meters at top.  Due to poor soil conditions, foundations on 160 drilled piles, each 0.5-meter diameter; pile cap prestressed.
  • Towerhead consisting of a lookout platform, a revolving restaurant, and two stories for communication services.  Due to large diameter of up to 29 meters, first towerhead as a composite structure of steel beams and concrete slabs.  Four antenna platforms.
  • TV-antenna carrier as steel lattice structure, covered with a plastic shell (RGF).

Design in cooperation with E. Heinle as architect.  Final structural design.
