AS Tech Automatische Schraubenspannvorrichtung

Automatic bolt tensioner

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 tensioner 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 Automatic…

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 austauschbarem Zugelement

Single-stage bolt tensioner 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 Mehrstufige Schraubenspannvorrichtung

Multi-stage bolt tensioner with exchangeable tension nut

The multi-stage bolt tensioner 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 Automatic…

AS Tech Industriehydraulik

Hydraulic systems

Our spectrum ranges from small mobile units up to stationary hydraulic systems. The operating pressures starts at 300 bar (4,350 psi) in the auxiliary hydraulics by 1000 bar (14,500 psi) in the working hydraulics up to 4000 bar (58,000 psi) in the high pressure hydraulics. It is important for us to analyze your application parameters…

AS Tech Druckübersetzer

Pressure Intensifier

Our pressure intensifier is useable with existing hydraulic pumps from low-pressure application or from hydraulic torque wrenches application – up to 2500 bar. Connection is possible to pumps made by all manufacturers and suitable for pressure ratio up to 1:16.
