ABSTRACT:
A mechanical tensioner for a nut-bolt assembly has two input elements engaging with one another and engageable by an actuating tool so that the input elements are turnable relative to one another in opposite directions, one of the input elements being engageable with a bolt so that when the input elements are turned relative to one another the one engaging element pulls the bolt in an axial direction, an output element engageable with a nut so as to turn the nut, and a transmission connecting the other input element with the output element so that when the other input element is turned the output element turns through the transmission and thereby turns the nut. The transmission is formed so that the output element is turnable with a speed which is substantially greater than a speed of turning of the other input element.
