1. A tamping device for soil compaction, comprisingan upper mass having a drive;
- a lower mass which has a soil contact element and which is movable relative to the upper mass;
a vibration-exciting device which is drivable by the drive and which brings about a working movement of the soil contact element; and
a manipulation device which produces a manipulation effect that influences the movement behavior of the upper mass and the lower mass with respect to each other, the manipulation device being provided in an operative connection between the upper mass and the lower mass; and
wherein the vibration-exciting device has a crank device driven by the drive, a piston which is moved linearly to and fro by the crank device, and a spring device which is arranged between the piston and the lower mass.

Abstract
A tamping device for soil compaction having an upper mass with a drive and a lower mass that can be moved relative to the upper mass with a soil contacting element. In order to cause a working movement of the soil contacting element, a vibration generating device is provided. In addition to the vibration generating device, a manipulating device, for example in the form of a damping body, is provided in an operatively connected manner between the upper mass and the lower mass. The damping properties of the damping body can be modifiable.

11. A tamping device for soil compaction, comprising
an upper mass having no a drive: -
a lower mass which has a soil contact element and which is movable relative to the upper mass; a vibration-exciting device which is drivable by the drive and which brings about a working movement of the soil contact element; and a manipulation device which produces a manipulation effect that influences the movement behavior of the upper mass and the lower mass with respect to each other, the manipulation device being provided in an operative connection between the upper mass and the lower mass, and wherein the detection device monitors a rotational speed of the drive and identifies deviations of the rotational speed from a predetermined rotational speed behavior. - View Dependent Claims (12)

13. A method of operating a tamping device for soil compaction, comprising:
-
providing an upper mass which has a drive; providing a lower mass which has a soil contact element and which is movable relative to the upper mass; providing a vibration-exciting device which is drivable by the drive and which brings about a working movement of the soil contact element, wherein the vibration-exciting device has a crank device driven by the drive, a piston which is moved linearly to and fro by the crank device, and a spring, device which is arranged between the piston and the lower mass; providing a manipulation device in an active connection between the upper mass and the lower mass; and changing a manipulation effect of the manipulation device depending on an operating behavior of the tamping device. - View Dependent Claims (14)
