Tapping Machine Type 3207 uses five hammers operated via tappets on a single shaft. The shaft is driven by a DC motor via a toothed belt and gearbox. The sound generator is robust, and is based around a welded aluminium chassis. Both size and weight have been minimized for easy transportation.

Three extendable legs with rubber feet support the unit during operation. The rubber feet are height adjustable with supplied gauges. This gives stable and level mounting during operation in accordance with the relevant standards.

The tapping machine is powered via the supplied mains adapter or an optional battery kit. The unit can be remotely switched on and off with cable AQ 0633 or Wireless Remote Control Option UA 1476.

  • Part of a complete building acoustics system featuring sound level meter Types 2250 or 2270
  • Remote operation via cable or wireless remote control
