Abstract

A tool having an operating element that is driven by an integrated power drive for the percussive, pounding or vibratory loading of a material to be worked, in particular a tamper, a vibration plate or a vibration roll for ground compaction or a hammer for breaking and/or drilling operations, can be guided using a handle. This handle is actively vibration-damped by at least one actively controlled or regulated compensation element, which counteracts the transmission of a vibration to the handle and which, depending on the vibration that can be transmitted to it and is produced in and/or on the tool, produces a compensating force and/or movement in the potential vibration transmission path from the location of production of the vibration to the handle.
