Whether assembling cranes, mill roll stands, turbines or pipe flanges – you will find that our tensioners are the ideal choice for a wide variety of different bolting applications. Plarad tensioners transfer the desired pre-tensioning force into the bolting joint without any torsion. The tensioner elongates the bolt using hydraulic pressure. In the next work step, the nut is threaded down with almost no friction
