AS Tech Mehrstufige Schraubenspannvorrichtung

Multi-stage bolt tensioning device with exchangeable tension nut

The multi-stage bolt tensioning device with exchangeable tension nut is used to generate high prestressing forces using small outside diameter. This tool is mainly used in the field of turbines, large bearings and pumps. Also in many different industrial applications. Standard design Hydraulic body with turnable, fixed support sleeve Drive gear, teethed nut and gearbox…

AS Tech Automatische Schraubenspannvorrichtung

Automatic bolt tensioning device

This purely axial method allows engaging the tensioning force exactly into the connection. The optimization of assembly time is the biggest benefit. Due to the automatic bolt tensioning device eliminates time-consuming screwing and unscrewing. The resulting time saving of the tensioning is approximately 50%. Standard design Patented thread clamping Drive gear, teethed nut and gearbox…
