Dantronik 45m total, only 20m used, plus rotator pole

Pick up of the 6 tower elements from DJ7WW in Auetal

getting the tower in Dec. 2006 - it took me dammned 8 years to install the tower...."only" over a year to get the permission.....

tower tunnel :-)

22. Sept 2014 - old BP60 tower on the left, new basement on the right

torque - Drehmomenttabelle für HV-Schrauben

treatment for the tower bolts

OKS 220 MoS2-Paste Rapid use this to treat the tower bolts - because of high torque

Digging the basement

on Monday 22.9.2014 I started with digging the hole for the foundation.
It took 8 hours.    4m x 4m x 2,10m depth.

foundation part / flange part

ELF delivered the galvanized flange parts

today was an exciting day!  the flange parts came back from galvanizing and Andre brought it from ELF to my home.
It looked so easy how he lowered the 300kg part into the pit. Roloff-Bau (concrete work) and ELF (welding) did a perfect job. Everything is levelled.. ......perfect 10 for both !

10. Oct. 2014 - 27 cubic metres = roughly 50 tons weight

today 27cubic metres of special quick mix concrete were poured into the pit.
