Overview and comparison of vibratortechnologies for formworks

BRECON Vibrationstechnik GmbH, Cologne, Germany


Since the 1950’s, the activities of Bosch have included the development and production of vibrators for precast element formworks. And since 1995, Brecon has taken over the further development of these technologies under license from Bosch. Much experience with the different technologies (pneumatic, electrical and electro-magnetic) and applications in the low (approx. 3,600 rpm) and high (from approx. 4,500 rpm) frequency ranges has also been gained during this period. This report describes the advantages and disad-vantages of the different techniques and shows which frequency range gives the best results for concrete compaction. The possibilities of conversion to the new SL technology is also discussed.
