BodAS (Documentation System) Automatic documentation of all screw connections in the force flow Transmission of the datas by radio (2.4 GHz) Evaluation of data via Windows (Printable) Usable for bolt tensioners as well as for torque tools Bidirectional data transfer possible Control of the aggregates with the corresponding PDA BomAS (Monitoring System) Measuring physical sizes…

AS Tech Spannwegunabhängige Ausführung mit Kontermutter

Clamping stroke independent version with locking nut

The hydraulic nut consists essentially of an internally and externally threaded piston, a cylinder and a locking nut. The hydraulic nut will be pressurized up to the desired pre tensioning force. This creates a gap between the locking nut and cylinder corresponding to the elongation and compression of the components. The locking nut will be…

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 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…
