Device and corresponding method for processing a hard surfacing. The device comprises a frame to be mounted to a vehicle, a support coupled to the frame, for carrying at least a first rotary processing unit for processing the hard surfacing, and wherein each rotary processing unit comprises a drive motor with a drive shaft, for rotating the rotary processing unit relative to the support; a substantially flat first disc comprising a plurality of processing heads for processing the hard surfacing; a substantially flat second disc coupled via vibration-damping coupling elements to the first disc and extending parallel to the first disc; a substantially flat third disc coupled via one or more deformation-reducing coupling elements to the second disc and extending parallel to the second disc, wherein the first, second and third discs form a stack of discs that is rotatable relative to the support.
The invention relates to a device for processing a hard surfacing, the device comprising a rotatable hammering unit configured to process the hard surfacing under the hammering unit with hammers, the hammering unit comprising a substantially flat first and second disc with a number of hammer wheels on the underside of the second disc, wherein the coupling between the first and second disc is formed by one or more vibration-damping coupling elements. The invention also relates to a method for processing a hard surfacing with a vehicle provided with the device described herein.
