PURPOSE: A bolting system is provided to secure at least two structures with axial tensioned bolts. CONSTITUTION: A bolting system has a bolt, a coupling nut, a hydraulic tensioner, and a lock nut. The bolt has a body with a threaded end and another end with a bolt head. The coupling nut is engageable with the threaded end of the bolt and has a top face having one or more dog indentations. The hydraulic tensioner has a hydraulic cell with an engagement end that engages the threaded end of the bolt. The hydraulic cell stretches the bolt while an engaging member of the hydraulic tensioner engages the dog indentations of the coupling nut with complementing, engaging member dogs. The engaging member rotates the coupling nut while the engagement end of the hydraulic tensioner tensions the bolt. The lock nut is engageable with the threaded end of the bolt. |
