The fully equipped BG 20 H went to work on its first site in Freiburg, where it started operations on the day it was delivered at the end of November 2019. By drilling was carried out in gneiss soil classes 6 and 7, the BG 20 H has proven its versatility and reliability on site. 

Here is the comment about the Bauer BG20 H from the engineer of the project:

"We are very satisfied with our BG 20 H BT 50 and extremely impressed with its low noise levels. This is a great relief for the machine operator as well as for site personnel and of course local residents."
