BESISTA® BVS pretensioning systems With the development of the BVS-230 and BVS-500 , BESISTA® offers extra-lightweight pre- tensioning systems which permit the economical pretensioning of our tension rod systems.
With the BVS-230, a tension of up to 230 kN can be applied by a single person in a few minutes. The BVS-500 allows pretensioning up to 500 kN. The applied force is displayed in kN.
Example: Red Bull Arena in Leipzig: 320 BESISTA M45 and M68 tension rods were pre-tensioned at a height of up to 56m at low cost, in a short time and without incident.

By simplifying the pretensioning process, our BESISTA pretensioning systems offer a consi-derably more cost-effective solution.Thanks to the direct connection of the pump to the hydraulic cylinders, the potentially hazardous on-site handling of „hydraulic hoses“ and associated risk of accidents are all but eliminated. As the loss of hydraulic fluid can be virtually ruled out, the build-up of force and display in kN are highly reliable. Both before and after the pretensioning equipment is loaned out, we prepare documentary photos for the structural engineer and the client. These document the conformity of the force display on the pump with the officially approved load cell. This provides evidence of their faultless operation.
Note: Since these machines are often out on loan, you are advised to reserve your machine well in advance.
