n Assembly platforms
The assembly platforms by goracon were specially deve-
loped for the assembly of concrete towers for wind energy
plants.
In this case, the innovation lies in that the concrete towers
are built from the inside. In the traditional assembly the
concrete tower is scaffolded from outside and then refitted
part by part. Not only is this extremely time-consuming
during the assembly, but also the set-up of these scaffolds
binds precious time resources and tower crane capacities.
During the assembly of concrete segments with the
, the platform is connected inside the first
concrete ring by a mobile crane, in compliance with the
requirements for passenger transport.
If the following concrete tower segment is attached, the
crane has already been positioned properly in order to
elevate the to the next level. After lowering
the crane gear, the is inserted and pulled to
the next tower section. During the upward movement, the
assembly operators must not leave the .
The fixation inside the concrete segment is carried out by
spring-actuated hang-up crossbars of the
adaptable to the respective diameter of the tower. The
superior platform rotatable over 360º of the
is additionally equipped with 4 to 6 telescopic bars as soon
as the tower segments are conically reduced. This conti-
nuous rotation of the superior platform and the telescopic
bars guarantees safe and easy work everywhere inside the
concrete segments .
Irrespectively of how high the tower will be,
all working positions can be reached by
different variants of assembly platforms, even
in case of different tower segment diameters

The main advantages of for the assembly of
concrete towers are the following:
• Easy assembly preparation.
• Rapid availability.
• Saving of crane capacities.
• Time saving because there is no need for a time- consuming set-up and refitting of the towers from the outside.
• Easy transport thanks to modular structure.
• Working inside the tower allows protection from the wind.
• All working positions can be easily reached.
• Rapid and efficient work of the assembly team.
The following standard variants of the are
available:
• GW-1410 module 0
• GW-1410 module 1
• GW-1410module 2
• GW-1410 module 3
