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 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…

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 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 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 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…
