Hydraulic tension tightening
For reliable, uniform and fast industrial tightening
Bolted assemblies are without a doubt the most widely used mechanical connecting systems.
We know that amongst the different causes of failure (overloading, design flaw, manufacturing defect, etc.), the most frequent one is poor assembly. It is therefore essential to have perfect control over the levels of tightening force and the precision with which it is achieved in order to obtain the required performance for the bolted assembly. The optimum solution for accomplishing this is tightening by hydraulic tensioning.
Hydraulic tensioning by elongation of the screw makes it possible to develop a great tension force for tightening bolts without any torsional stress or friction, but with high precision and very good repeatability.
