Quick-Connection
Simple interlocking between tower
and slewing platform with only one
hammer blow.
One-Man-Assembly
Patented, semi-automatic bal-
lasting tongs and the ballast
centring enable one-man as-
sembly.
Fast climbing
Up to 6 tower sections can be inserted comfortably and without
ground contact.
The better ballasting
The interplay of hoist and assembly winches enables fast and
comfortable mounting of the counterweight. With the assembly
winch, the tower moves up to 5 metres when unloading the
counterweight. Ballast plates are quickly mounted with the
hoist winch.
CC-Ballast
Bolted ballast plates reduce the time for mounting of counter-
weights by up to 50%. Only 8 hoists are required. Save time
and money!
