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
