New generation of efficiency-enhanced,
emission-free vibrating tampers

Currently used combustion engines for vibrating tampers leave only little Period
room for reducing emissions and improving handling. The ILK, together with 01.07.2018 – 30.04.2021
the project partners RAVI Bau- und Mietgeräte GmbH and EMEC-Prototyping
GmbH, is meeting the increased requirements for emission-free operation, Project Director
handling and occupational safety by developing an electric, battery-powered Prof. Dr.-Ing. Niels Modler
drive system for a new vibrating tamper. The work is taking place within a proj-
ect funded by the SAB and, in addition to the development of the electric drive Contact Person
system, also includes scientific investigations to reduce the vibration load on Dr.-Ing. Martin Dannemann
the operator by means of adapted mechanisms and materials. For example, Philip Steinbild
the demonstrator developed at the end of the project uses compliant struc-
tures made of glass-fibre-reinforced plastic, which dampens the vibrations Funding
transmitted to the operator through their material properties. Furthermore, • Free State of Saxony
novel compliant mechanisms for power transmission in connection with lin- • European Regional Development Fund
ear drives were investigated. This design innovation has a high potential for (ERDF)
reducing the number of components and the vibration load on the operator, • Sächsische Aufbaubank (SAB)
which is of particular interest in the construction machinery environment.
