Small Tapping Machine

The small tapping machine system Gösele is a seismic source, which is based on the periodic impact of a moving mass.

Deviating from the norm, it is primarily intended for exiting components, namely walls, fixtures, pipes etc.. However, it can – with restrictions also be used for ceilings. Using the standard tapping machine, gravity acceleration drives the colliding hammers. Using the small tapping machine system Gösele an electro-dynamic force generated by periodic direct current pulses is used to drive the hammer.
