AS Tech Mehrstufige Schraubenspannvorrichtung

Multi-stage bolt tensioning device with exchangeable tension nut

The multi-stage bolt tensioning device 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…

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.

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 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 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…
