Revolution in tamping technology

Improved productivity and less impact on workers and the environment.


This year, Rhomberg Sersa Ireland has installed System7 technology on a Plasser & Theurer Unimat 08 Compact tamping machine from Irish Rail and is the first company worldwide to do so.


System7 tamping banks are unique in that no rotating parts are required. The fully hydraulic drive and the bank only vibrate during placement and compaction of the ballast. This technology also “reads” the ballast to be put in place and adjusts the feed and compacting pressure accordingly. 


In addition to the improved results of the tamping process, the noise generated is significantly reduced compared to older tamping units. Noise emissions, vibrations and the amount of silica fume are reduced by up to 50%, thus minimising the burden on operators and the environment.
