Over the past few years, TT
Fijnmechanica B.V. has built up a top-class reputation
manufacturing stressing jacks. Stressing jacks are manufactured
with tonnages varying from 110 tons to 1,000 tons with
various stroke lengths. The majority of the stressing
jacks are manufactured at the client’s request because
of the often client-specific requirements. That is why
close cooperation with the client is fundamental. |

Stressing jacks are used in
prestressing technology for the stressing of single and
multi-strand systems and are equipped with hydraulic locknoses
or self-tightening locknoses. The locknoses are used in
order to secure the wedges thereby guaranteeing good anchoring.
Depending on the client requirements multi-use stressing
heads can also be supplied. Jacks are tested for both
safety and function and can be calibrated for stressing
strength if so desired. |
