  • eight to nine platforms are usually provided for a 6-stage preheater, so that the building tower can reach a height of 160-170 m.
  • the construction time of the preheater tower is particularly time-consuming and usually takes 14 to 19 months.

  • the current method is time consuming and expensive with the use of expensive large cranes and many overhead lifting maneuvers for steel and equipment into the building. These maneuvers are also associated with a risk of accident that cannot be neglected.
  • the invention is therefore based on the object of developing a preheating tower and a method for erecting such a preheating tower with which the construction and assembly time can be shortened considerably. According to the invention, this object is achieved by a tower structure of a preheating tower with the features of independent device claim 1 and by a method for erecting a preheating tower with the features of independent method claim 9.
