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 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

Electrical hydraulic power unit for Torque wrenches

Qur electro-hydraulic power units have been developed for all common hydraulic torque wrenches. The units are ideally suited for continuous operation thanks to active recirculation cooling. Due to the compact and ergonomic design including support frame, a safe and comfortable screwing ist possible.

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…
