Praxistipp: Wie Coiler und Stahlseil beim TWISTER gewechselt werden

The protective boots from Rosenbauer are made from high-quality parts only. Nevertheless, even the best products are not immune to damage in demanding operations. If damage does occur, it is often possible to repair the boots with little effort. For example, switching the steel cord and coiler of the TWISTER and TWISTER-cross is done in a few minutes.


The BOA® lacing system is, for many fire departments, the system of choice: With a few turns of the coiler the steel cord is tightened and gives good support in the protective boots. The pressure distribution is uniform, the boot is laced quickly, and the lacing can be readjusted quickly during operations. When cleaning, no annoying obstructions are caused by loops or laces. The TWISTER and TWISTER-cross - like all operational boots from Rosenbauer - have been proven to be incredibly robust over the years. Only the toughest and most powerful lacing system version from BOA® is used. Nevertheless, in some cases - for example due to mechanical stress - it may become damaged, requiring the coiler and the steel cord to be replaced.

Steel cord and coiler replacement: step by step

 

Tip before you start: If both boots need a replacement, one should always be kept in its original state. This way, you always have a boot as an example. It is also important to choose the right cord length for each shoe size: lengths for sizes 36-40 and 41-52 are available.

Step 1: With a tool (e.g., a small screwdriver), remove the coiler. For this, simply exert pressure at the marked position and rotate the coiler to the right. Now you can pull it out

Step 2: Now pull out the steel cord with a wire cutter or similar. Threading out the cord from the coiler is most easily achieved with a pair of pliers. The steel cord is now pulled out of the boot feeders too.

Step 3: The new steel cord is threaded in. It is recommended to use the second boot as an example. It may be the case that you have to continuously push the steel cord in some places with pliers.

 

Step 4: The steel cord is attached to the coiler according to the instructions (included with any replacement steel cord or coiler). Here too, refer to the second boot.

 

 

Step 5: The coiler is again fixed to the corresponding insert on the boot. It is properly latched when you hear a clicking sound. Now wind up the steel cord.

 

 

 

Finally, you should also test whether the lacing system is working properly by putting on the boots and tightening the coiler firmly. Should the damage affect only the coiler, this can also be replaced individually. However, Rosenbauer recommends replacing the steel cord and coiler together.


In some instances, it is not possible to repair the coiler yourself. This is the case when permanently connected components on the boot are damaged, for example. In such cases, you should send the boots to Rosenbauer, where experts can replace the insert.


Rosenbauer's repair service is used by many fire departments: Protective boots are provided with new soles, seams are replaced as needed, and individual parts are replaced. Thus, with often only minimal effort, the life of a boot is considerably extended.
