bo becomes e.g. a position of the unbalanced bodies, in which the Eccentricity of the vibrations generating. Crowds is smaller, a higher speed is assigned, while "at a greater eccentricity of the same hatred that how already mentioned, by shifting unbalanced bodies, a lower speed is set.

Preferably, the device for the two is dependent changes to be made in such a way that by means of a single control unit, both the yr modification; like the beam or »switching on eggs associated Speed takes place. For example, you can use an operating lever for the reversing gearbox as well as for the speed-regulating gearbox as well as their clutches to be operated when retained.

In another embodiment, an operating element, for example a hand lever, can be provided for the reversing gear and the speed change gear; these are according to the invention by locking means in dependence, brought so dai3 of an operation lever can only be placed in that position, which causes the operating state which the operating condition is associated with, welcner by the insertion of the first operating lever was prepared ds rird so by The locking device ensures that the fog for the speed can only be used in the division that corresponds to the position of the IJnv / ucht-

body disengaged.

In a preferred embodiment, the fixed and loose unbalanced bodies are designed and the speeds are graded so that that the same centrifugal forces at different speeds be generated. This embodiment is based on the idea that it is useful for various applications is to increase only the frequency, but not the fluid force, oo can be z.ü. coarse-grained and deeper-lying material ijodensCiiichten compact well if at low frequency large imbalances are effective, while fine-grained material and they contributed directly to the surface a higher frequency and smaller effective unbalance masses well compacted.

The disadvantage of known vibratory rollers, in which only the Speed of rotation of the inflammatory bodies is changed and. so the Centrifugal force changes quadratically, is with the vibratory rollers • en - "_ i .; eier invention eliminated. In addition, aie has with the vibrating roller geml-Jä of the invention provided change of .Speed in steps has the advantage that the power of the drive gate can be better utilized, while larger motors are required with stepless speed control.

The overriding facilities that are provided are two Operating levers are available, can be mechanical and / or electrical devices.
