Effective protection against self-loosening in large bolted connections Large bolted connections with a nominal size of ≥ M24 can only be pre-tensioned by hand with great effort. The torque required to tighten the connection is simply too high, which means that electrically, pneumatically, or hydraulically powered torque tools must be used. However, the use of…

AS Tech has longtime experience in the manufacture or repair and installation of hydraulic cylinders. Use this experience to your advantage and get a comprehensive service from one source. All cylinders and components are manufactured in our own production . You benefit from an expanded knowledge and years of experience of our team of designers,…

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…

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…

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.

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…

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…

BodAS (Documentation System) Automatic documentation of all screw connections in the force flow Transmission of the datas by radio (2.4 GHz) Evaluation of data via Windows (Printable) Usable for bolt tensioners as well as for torque tools Bidirectional data transfer possible Control of the aggregates with the corresponding PDA BomAS (Monitoring System) Measuring physical sizes…

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. Standard design Supply voltage 90-264 V / 47-63 Hz Pressure 700 bar…
