Abstract (en)
[origin: EP0791443A2] The shuttering has a skin supported by a frame of steel profiles on the external vibrator for compacting the concrete. The entire shuttering is mounted on torsional vibration damping elements. A strong lengthwise support is rigidly joined to the shuttering. Pendulum vibrators (13) are fixed to one of the lengthwise sides of the lengthwise support (12,21) and are fixed to horizontal rotor shafts connected for forced synchronisation.
