Precision under tension – why bolt tensioners matter more than ever
In critical bolting applications, torque alone is not always enough.
Bolt tensioners provide a controlled, direct preload – independent of friction – ensuring maximum accuracy and repeatability.
Whether in wind energy, heavy industry, or fl**ge connections:
Using hydraulic tensioners significantly reduces the risk of uneven load distribution, bolt fatigue, and costly failures.
At PLARAD, we offer both single-stage and multi-stage tensioners – designed to adapt to different space conditions, load requirements, and application complexities.
✔ High precision through direct axial force
✔ Uniform bolt elongation across multiple studs
✔ Ideal for safety-critical connections
✔ Scalable solutions for simple to complex assemblies
Choosing the right tensioning solution is not just a technical decision – it's a matter of reliability, safety, and long-term performance.
