Therefore the pre-tensioning force of bolts is independent on the friction coefficient. The bolt tensioners are actuated by means of a hand pump or electric pump or pneumatic pump with the output pressure of 800 or 1600 bars depending on the unit version. Optional and customized designs of the bolts tensioners with various values of pre-tensioning force, size and application procedures are available upon individual orders.
