Finger joint dovetails bridge, highway demands

The Wabo Trident Finger Joint System is designed and built to handle movements and rotation about all axes, as opposed to a standard alternative that is limited to longitudinal, and in some cases, vertical movements. Along with its unique ability to accommodate transverse movement, the system can also handle large movements, including seismic events, and restore its original position via internal torsional spring components. The advanced system design also allows the Wabo Trident to be installed quickly with minimal downtime and lane closures.

Watson Bowman Acme’s new Trident Finger Joint System is capable of handling complex structural movement among all principal axes.

“The Wabo Trident was developed to address a unique customer need requiring a solution that was not currently available,” says Watson Bowman Acme Operations & Engineering Manager Gary Moore. “WBAs Innovative Solutions Team met the challenge with a custom expansion joint system that can be used in many applications.” Watson Bowman Acme/BASF Construction Chemicals, Amherst, N.Y.,
