Hydraulic Bolt Tensioners
Designed for screwing and unscrewing nuts with calibrated capacity in heavy duty fasteners when performing installation and dismantling and repair work in all industry branches.
The work of the bolt tensioner is based on pre-stretching of a stud (bolt) with a capacity equal to the required capacity of screw connection fastening and the subsequent tightening of nuts without the application of capacity against stop into the support surface.
Bolt tensioner can be grouped and powered by a single pressure source through multi-way valves, which is the essential solution when you need to produce a synchronized tightening of the large number of bolted joints.
Complete with removable holders and adapters according to the operating range.
