Fastening is one of the most crucial processes to be automated in the factory of the future. Based on more than 45 years of experience in high-precision assembly of large parts, Broetje-Automation has developed one of the largest fastening machines in the wind power industry. The Stator Torque System is a tailored automated bolting system for the automatic fastening of large bolts in the stator section of a wind turbine.

The process integrates the automatic fastening of large bolts in the stator section of the turbine. The tightening of the bolted connections in various stages, in this case up to 2200 Nm, is carried out fully automated. Broetje-Automation’s proprietary SCALE sensor system ensures a smooth and highly accurate fastening that dramatically increases the speed and accuracy.
