Abstract (en)
[origin: EP0011692A1] 1. A mobile tearing-up apparatus for treating a ground surface (4), having a heating device which heats up the ground surface (4) and having a number of tearing-up spikes (1, 2) for penetration into the ground surface (4) and functioning as tearing-up tools upon moving the tearing-up apparatus, characterized in that some tearing-up spikes (11) are attached to the casing (8) in an electrically insulated manner and are connected to a high-frequency generator and serve as "live" electrodes and the remainder (2) as earthed electrodes of the high-frequency heating apparatus exhibit earth potential and are electrically connected to the casing (8).
