Anchor function principles – Heavy-duty anchor Guidebook Part 3
The metal cone must travel a certain distance inside the drop-in anchor in order to properly expand the sleeve in the borehole. The ETA-controlled setting tool ensures the correct distance. Advantages: Easy assembly (no setting tools, exception: drop-in anchors) Immediate load-carrying capacity (no curing times) Self-locking load bearing capacity: As soon as load is introduced via the add-on part, the cone bolt continues to pull into the sleeve.
