The third Liebherr LRB355.1 from Votquenne is again fully equipped with Olivier drilling tools for full displacement screw piles. The BAT450.1 rotary drive is provided with a Olivier XL-coupling and a reduction piece to the standard Olivier coupling with the corresponding drilling pipes. At the bottom there is an Olivier auger head d41/61 type Votquenne. This setup operates in an open concrete system where concrete and reinforcement are placed through the funnel into the drilling pipes.
