TENSOR delivers complete bolt tensioning systems including digitally controlled pump units with multiple redundancies. 

The bolt tensioner from M80 (3” UNC) and upwards are assembled with a counterbalancing device to make it easier to turn the puller sleeve down/up, an indicator to prevent over-stroke, and an air-drive to rotate the puller sleeve up and down. We can also deliver quick hoists for the tensioners.

On-demand we also deliver optimized tensioning and detensioning programs.
