A soil compaction device has a receptacle in which a cage can be placed to hold a battery. At the external side of the cage there are spring-damper elements provided that keep the excessively strong acceleration loads away from the battery. The cage and the battery can be pulled out of the receptacle in a simple manner in one piece.

The invention relates to a guiding cart for a manually guided tool, for example an abrasive cut-off machine, which comprises a movable frame on which a first and a second locating recess for inserting the abrasive cut-off machine are provided. A locking device is assigned to the first recess by means of which forces can be applied to the abrasive cut-off machine in the direction of the first locating recess and the second locating recess. In this way the abrasive cut-off machine can be reliably and rapidly fixed to the guiding cart after it has been inserted into the locating recesses. The insertion of the abrasive cut-off machine is facilitated by inclined inserting elements situated in the locating recesses.

A device for generating directed vibrations has two centrifugal weights which are independently driven at the same speed of rotation but in opposite directions. The centrifugal weights are supported on a largely stiff carrier secured by a holder to a bracket. The holder allows the carrier to move relative to the bracket. When the centrifugal weights start moving, they become synchronized within a short period of time and generate vibrations which can be used in the desired manner via the bracket.

Device for generating directed vibrations

A vibration generator for generating directed vibrations in a compacting device includes a housing and a first and second flyweight shafts rotatably supported in the housing and extending parallel at a distance to one another. The flyweight shafts have a respective flyweight connected thereto. A first and second intermediate shafts are rotatably supported in the housing and extend parallel to and between the first and second flyweight shafts. Gear wheels positive-lockingly connect the first and second intermediate shafts to one another, the first intermediate shaft to the first flyweight shaft, and the second intermediate shaft to the second flyweight shaft. In this manner, the first intermediate shaft and the first flyweight shaft, respectively, the second intermediate shaft and the second flyweight shaft rotate in opposite directions. One of the intermediate shafts has connected thereto two gear wheels, with one being coupled to the first flyweight shaft and another coupled to the second flyweight shaft. A rotational drive for driving the first and second flyweight shafts so as to rotate in opposite directions with identical rpm is provided. A phase-adjusting mechanism changes in a controlled manner the phase angle between the first and second flyweight shafts by adjusting the angular position of one of the two gear wheels relative to the second intermediate shaft in a controlled manner during operation of the vibration generator.
