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 3000 bar. Connection is possible to pumps made by all manufacturers and suitable for pressure ratio up to 1:16.

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 Sonderhydraulik

Special-purpose hydraulics

We do not limit ourselves to existing products to the technique of axial pre-tensioning of bolts. Through in-depth knowledge and extensive experience in the field of high-pressure hydraulics, we are specialists in the creation of customized solutions.

Hydraulic systems

Our spectrum ranges from small mobile units up to stationary hydraulic systems. The operating pressures starts at 300 bar (4,350 psi) in the auxiliary hydraulics by 1000 bar (14,500 psi) in the working hydraulics up to 4000 bar (58,000 psi) in the high pressure hydraulics. It is important for us to analyze your application parameters…

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 Einstufige Schraubenspannvorrichtung mit austauschbarem Zugelement

Single-stage bolt tensioner 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.
