Installation for the new big tower in 2014 – a diary
see some pictures and details from the installation of my new antenna tower.
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…..
September 22nd 2014 –
start with new tower foundation
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 8.10.2014 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.
