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 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.

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 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 Einstufige Schraubenspannvorrichtung mit austauschbarem Zugelement

Single-stage bolt tensioning device 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.
