for continuous flight auger (CFA), double rotary and full displacement methods
The drilling assistant regulates the crowd force and speed of the rope crowd system. This is matched to the speed and torque of the rotary drive. Even during subsequent extraction and simultaneous concreting the automatic control system takes over and also ensures that the optimum amount of concrete is filled. The result is a high-quality cast-in-place pile.
The correct match between the extraction speed and the amount of concrete filled is decisive for the required pile diameter in this method.
Once activated, the drilling process runs automatically. The values, preselected by the operator, are held constant by the control system. The parameters can also be adjusted during the drilling process.
The speed and the torque of the rotary drive as well as the crowd force are perfectly matched during drilling. Through appropriate parameters the progress of the drill can be adapted to suit the soil conditions.
During simultaneous extraction and concreting through the hollow stem, the control system adjusts the extracting speed and both the amount and pressure of the concrete accordingly.
