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 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 Automatische Schraubenspannvorrichtung

Automatic bolt tensioning device

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 tensioning device 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…

AS Tech Einstufige Schraubenspannvorrichtung mit Gewinde im Kolben

Single-stage bolt tensioning device with threaded puller

A feature of this bolt tensioning device is its low profile. The single-bolt tensioning device is low-cost and thus has a short payback period. It is used in many different industrial applications.
