Abstract
A tensioning system for tensioning a stud is provided. The system includes an adapter ring having an external surface, an internal surface engaging the external surface of the stud or puller screw, and at least two bores defined therein. The posts have first and second ends and are disposed in the bores. The first ends are supported by a stop surface, and the second ends extend outwardly from the bores. A cylinder includes an internal surface engaged with the external surface of the adapter ring. First and second pistons are movably positioned within the cylinder with an intermediate cap disposed therebetween to define first and second hydraulic chambers. The first piston is configured for being supported by the second ends of the posts. The hydraulic chambers are hydraulically connected to one another, whereby providing a hydraulic fluid in the chambers operates to apply a tension force on the stud.
