TRAXX handles the assembly and tightening of a structure at your site.
In what situation?
-
You are looking for a service provider for the assembly and tightening of your bolted structures.
-
You want to be sure that you have assembled your structure correctly and that you are applying the same tension to all of the bolts.
-
You are seeking a precision of ± 5% on the tightening of your assemblies.
How does the operation proceed?
The operation proceeds in 3 stages.
The first stage is the characterization phase of the screws, which involves testing the screws to establish the properties specific to each batch of screws. This stage takes place before the construction site.
The second stage is the construction site setup: the most suitable tightening tools are selected (hydraulic wrench, extender, etc.), the intervention team, the configuration of the TRAXX-M2 tension measurement system, and the intervention schedule and procedure are defined. Then, the tensioning can begin. Our operators apply the pre-defined tension by the specifications to each screw.
During the tensioning, the values measured in real time by the TRAXX-M2 measurement system are considered to be accurate. The procedure is simple: before the tensioning, the sensor of the TRAXX-M2 measurement system is placed on the head of the screw. The operator follows the induced tension in real time and stops the tensioning when the optimal value is reached. A daily report is prepared for each day of intervention.
Finally, at the end of the service, a report is provided containing all the data from the construction site (date, time of tensioning, screw number, screw type, applied tension). In addition, all of this data is recorded by the acquisition system, which will make it possible in the future to track the evolution of the assembly and thus easily detect any anomalies.
