New demolition cutter breaks Leipzig's "prefabs" CC 3300 from Atlas Copco used in controlled reverse construction of several 11-story prefabricated concrete buildings.
The city of Leipzig is ridding itself of many of the prefabricated concrete housing settlements built extensively in the 1970s under the former East German regime. Architecturally bland and technically outdated, they can only be integrated in the modern cityscape and adapted to modern living standards at great expense. In many cases, complete refurbishment is simply not worth it. The only alternative is to pull them down.
Demolition contractors Ruppert GmbH & Co KG, Frickenhausen (www.ruppert-erdbau.de) recently tore down several 11-story housing blocks situated literally a stone�s throw from a shopping center.
The precision demolition work on the roughly 40 meter high buildings called for expert excavator operation and special equipment. Ruppert used a Liebherr 974 with a 37 m demolition boom and an Atlas Copco CC 3300 U demolition cutter.
Weighing in at 3.3 metric tons, the cutter was fitted with universal jaws suitable both for breaking concrete and cutting through rebar.
Excavator operator Klaus Wiessmann: �We had to work with great care; one part of a facade falling in the wrong direction could have caused considerable damage to neighboring buildings. The cutter has a rotary drive for exact positioning, which is particularly important when working at such heights.�
With a breaking force of 109 tons on the outer teeth and a cutting force of 400 tons on the blades, the CC 3300 has considerable power reserves making it ideal for light- to heavy-duty building demolition, industrial demolition, cutting steel girders (general structural steel), and for secondary breaking and material sorting.
