Good grip on the road – Tests and technical reports for your products

Wheels are technical products with high demands on functionality and on manufacturing quality. To design the wheels for sufficient strength, the different loads with their resulting stresses on the wheel-body must be known.

The influences on the loads and stresses within the wheel and with that the influences on the strength of the wheels which can be specified are assessed and tested by us. Basis for our tests are the national and international legal requirements and the manufacturer’s demands. Tested wheels are classified as sufficiently dimensioned, when they withstand the loads and reach the intended life span under test conditions. High manufacturing quality assures that all produced wheels have the same high production quality.

We test and assess your wheels on different test stands for a god product- and manufactur-quality.
