AS Tech Elektrohydraulikaggregat auf Akku

Electrical hydraulic power unit – battery driven / Power unit for tensioning devices

Our battery-driven electro hydraulic pumps are available in the pressure ranges of 1000, 1600 and 2500 bar. They are mainly used where a network supply is not available or difficult to reach. The two batteries will allow a continuous operation for approximately 2.5 hours. In the meantime 2 additional batteries can be charged with our…

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.

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 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 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 Spannwegabhängige Ausführung mit Passblech

Clamping stroke dependent version with spacer plate

The hydraulic nut consists essentially of an internally threaded cylinder, a piston and a splitted spacer plate. The hydraulic nut will be pressurized up to the desired pre-tensioning force. This creates a gap between the piston and cylinder corresponding to the elongation and compression of the components. In this calculated gap the corresponding spacer plate…
