Bomatec manufactures and assembles the magnetic return yokes for the magnetic wire rope testing devices from ROTEC GmbH in Stuttgart, Germany, entirely in-house at its site in Switzerland. The return yokes guide the magnetic flux in the sensor head and are a key component for the accuracy of wire rope inspection. They are made from soft magnetic materials designed for efficient flux guidance with minimal losses.
What does Bomatec supply for ROTEC's magnetic rope testing devices?
Bomatec produces the magnetic return yokes as part of its magnets, assemblies and sensors, the field in which the company has specialized for 30 years. The return yokes are not purchased and simply installed. Bomatec makes them itself, from material selection through to the finished assembly. Assembly also takes place entirely in-house, with no external supplier steps in between.
How do ROTEC's magnetic wire rope testing devices work?
ROTEC's devices use a sensor concept of induction coils and up to 48 Hall sensors, which are digitized directly in the sensor head. This allows flaws in wire ropes to be not only detected but also located in three dimensions. The magnetic return yoke closes the magnetic circuit and largely determines how efficiently and reliably the sensors can operate.
Why is in-house assembly in Switzerland a quality advantage?
Bomatec manufactures at several production sites worldwide, but the return yokes for ROTEC are deliberately made in Switzerland. This enables short communication paths between development and production, seamless quality control at every production step, and fast response times for modifications. For ROTEC, and ultimately for the users of the testing devices, this means consistently high, traceable component quality.
Where are magnetic rope testing devices used?
ROTEC's magnetic rope testing devices are used on cable cars and ropeways, bridges, cranes, offshore installations, amusement rides and in mines. They are used wherever the condition of wire ropes must be inspected regularly and reliably. Further technical details on ROTEC's magnetic rope testing devices can be found on the manufacturer's website.
What does the partnership mean for the future of rope testing?
For Bomatec, working with ROTEC shows how Swiss precision manufacturing and German engineering can join forces to advance safety-critical testing technology. Bomatec's high level of in-house manufacturing allows it to work with ROTEC on new sizes and further developments, for example as part of the "Rope Testing 4.0" concept, with which ROTEC is driving the digitalization of rope inspection. Bomatec will continue to contribute to the safety of rope applications worldwide.
