- Summary
- Altec has learned that the threaded hardware between the rotary joint and slip ring could have been installed incorrectly on certain AA, AN, AN-OC, AM, and A Class aerial devices built from January 2021 to February 2022. This can cause the rotary joint restraint bracket to disengage from contact with the rotation-bearing cap screw heads, allowing the outer housing of the rotary joint to turn in the pedestal and cause damage to the attached hoses.
