- Most helical pile failures in the field occur at the joint. This eliminates joint weakness. Under higher torque bolts and joints elongate and get distorted making them weaker.
The typical industry standard helical section has holes drilled into the ends of the tube section only relying on the steel tube for strength.
- Since both the box and pin connections on Helical Anchors are precision machined, we can hold tolerances to .001 of an inch. This gives the connection a very precise fit adding lateral support. This connection also allows us to shoulder or transfer the load on the anchor walls vs. the standard method of relying on the bolted connection.
- Helical Anchors have the highest torque ratings in the industry!
- We can use smaller diameter piles (shafts) for the same load capacity.
