Europe´s highest located demolition Site
Technology performance on the highest level
Certainly there are barriers but just because they are there is motivation for us to break them time and again. At Jänschwalde and Boxberg power plants we have climbed up to a height of more than 300 meters to demolish stacks from top to bottom with especially developed technology in an environmentally friendly way.
The SAK 30 complex consists of an externally positioned work and safety platform (SAK 30-K), providing maximum safety for personnel and the construction site, and the internally positioned modularly extendable demolition machine (SAK 30-A) capable of operating with up to three hydraulic pliers, winches, hammers or crushing devices.
It can demolish tower-like buildings, no matter how high, from12 to 30 meters in diameter and a wall thickness of up to 80 centimeters. The bitten-off pieces then fall down inside and are moved away. Our staff, with many years experience operate around the clock, to make sure that nothing but a green meadow remains at the end.
Video RTL Welt der Wunder “The highest demolition site in Europe”
http://www.tvf-altwert.de/de/wp-content/uploads/2008/09/sak30.flvThe film describes the technical challenges of demolishing the Chimney Y2 in Jaenschwalde. After the installation of a new de-sulphurisation plant the concrete giant was no longer required and needed to be removed. However, space is too limited for a controlled explosion and no crane in the world is capable of working at such a height. For this reason, the company “TVF Altwert” took on the task with their specially designed construction SAK 30. Shift for shift, their three excavators remove the chimney with surgical precision. This job makes the highest demands on the excavator operators, not least the ability to work at a great height without feeling dizzy.
2002-2004 Project power station Jaenschwalde
Objectives: The demolition of a chimney in power station Jaenschwalde, owned by the Vattenfall Europe Generation Group. Using the specially designed SAK-30, the demolition of the chimney from 300metres down to 45 metres should be completed by March 2004. The first 320 metres of the four internal gas pipes were demolished using a technique specially designed for the operation. A centrally located revolving crane was installed, which was able to demolish each pipe bit by bit down to the bottom of the chimney.
History: The chimney was built in the 1970s as the 500 megawatt plant was constructed. The construction of a de-sulphurisation facility in the 1990s made the chimney obsolete. Due to the close proximity of the working power station only the piece by piece removal was possible. The work began at the end of 2001.
Dimensions: The chimney is made of steel reinforced concrete with a wall thickness of up to 65centimetres. The total quantity of material is around 30,000tons. The machine used has already been successfully used in Boxberg power station. It is intended, after servicing, to use the machine for similar deconstruction projects.
