  • Patent number: 8491222
    Abstract: A vibration tamper for compacting subsoil comprises a superstructure and a substructure, with the superstructure comprising a motor and an eccentric disk which is driven by the same. A connecting rod is eccentrically mounted on the eccentric disk, which connecting rod converts the rotational movement into a linear movement. The substructure comprises a tamper foot with a tamper plate which is driven by the linear movement of the connecting rod into a tamper movement along a tamper axis. As a result of the bent portion of the connecting rod, the tamper axis is disposed in a plane which is disposed parallel to a plane opened up by the bearing of the connecting rod on the eccentric disk against a direction opposite of the advancing direction of the vibration tamper.

  • Patent number: 8332105
    Abstract: A method and a system is described for controlling at least one compaction machine in which the oscillations propagating from the compaction machine in the ground are detected by means of a sensor at least at one relevant measuring location. The measured oscillation values as detected by the sensor are sent to a data-processing unit which then compares the same with a permissible oscillation limit value for the respective measuring location. Upon exceeding the limit value, at least one compaction parameter of the compaction machine is changed in such a way that the measured oscillation values as measured at the measuring location are set by a control loop circuit automatically to a value smaller than or equal to the oscillation limit value.
