| The auger drive BA or the auger drive with centre boring DBA can be operated at all common hydraulic excavators as well as mini excavators. Together with casing twister cased drilled shaft installation is possible. For the production of CFA piles a swivel for concreting must be mounted to the auger drive, so that immediate concreting is possible during the pulling procedure. The auger drive can be applied for ground release drilling, ground investigation, soldier pile installation, displacement augering, CFA piles, injection and soil improvement for foundations.
