摘要： The present invention relates to a rear finisher for smoothing an outer surface, which is attached in the forward direction behind a device for outdoor preparation and particularly for snow piste preparation. In order to allow a uniform appearance of the piste surface, the rear finisher has a guide device, which is applied so that the material to be prepared is guided in front of the bottom of the rear finisher and subsequently smoothed thereby. Furthermore, the present invention relates to a method for smoothing an outdoor surface, in which the outer surface to be smoothed is smoothed by two different oscillating means guided one after another on the outdoor surface.

摘要： A method and a device are provided for determining the degree of compaction during ground compaction with a roller or a vibrating plate compactor comprising a top section and a vibrating plate. The method involves determination of one or more amplitude values of the vibration at approximately the excitation frequency of the plate relative to the top section, one or more amplitude values of one or more vibrations of the plate relative to the top section at a maximum of 60% of the excitation frequency, and the quotient of the aforementioned amplitude values as a measure of the current degree of compaction of the ground. The device includes a sensor for non-contact detection of the relative movements between the top section and the vibrating plate or roller.
