AS Tech Einstufige Schraubenspannvorrichtung mit austauschbarem Zugelement

Single-stage bolt tensioning device with exchangeable tension nut

By the feature of the exchangeable tension nut we create in common with a hydraulic cylinder and multiple supplementary sets, an assembly tool for bolts and nuts used in general engineering. It is highly cost effective, for example if for a machine, a tool for different thread sizes is necessary.

AS Tech Lufthydraulikaggregat

Air-Hydraulic Power unit

With our air-hydraulic pumps you can generate pressures up to 2500 bar. With the selected increasing ratio, the pump can be adjusted to the existing air pressure network. The air-hydraulic pumps are mainly used in explosion-proof areas. A pressure regulator installed at the input side can adjust the hydraulic pressure at the output side. The…

AS Tech Elektrohydraulikaggregat

Electric hydraulic power unit / Power unit for tensioning devices

Our electrical hydraulic power units produce a very high flow rate at operation pressures up to 2500 bar. The electro-hydraulic power units are available for several voltages and in different power configurations. Due to the considerable greater flow rate in comparison to the hand-lever and air-hydraulic pumps, these power units are mainly used for quick…

AS Tech Einstufige Schraubenspannvorrichtung mit Gewinde im Kolben

Single-stage bolt tensioning device with threaded puller

A feature of this bolt tensioning device is its low profile. The single-bolt tensioning device is low-cost and thus has a short payback period. It is used in many different industrial applications.

AS Tech Handhebelpumpe

Hand-lever pump

With our hand-lever pumps you can easily generate a hydraulic pressure up to 2500 bar. The pumps are mainly suitable to operate small devices or during maintenance. Manual operation is independent from an external energy supply. Of course, we are pleased to offer you special solutions regarding tank size, max. pressure and construction of the…

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…
