When a castor is in motion, it has more than one force acting upon it. Its development must therefore take into account the interplay of all of the forces acting on it in order to guarantee the highest quality standard in terms of durability. A distinction is always made between the two loading states: Static and dynamic. In the first case, the acting force and its direction of action remain unchanged. The castor stands still and is subjected to a constant load. In dynamic loading, however, the force and direction of action do not remain constant.
The castor is in motion and the load is determined by numerous influencing factors – starting with the weight of the load, through to the acceleration and speed, the duration of travel and the associated temperature changes. All these factors affect the individual components and materials of the castor. It is also necessary to consider possible impact loads. These include forces from above, below or from the sides. In some applications, the castors must withstand loads that are well above those of the standardised test conditions. This is precisely why we have our own test centre, where products are tested in the development phase according to the individual requirements of our customers.
Our production is subject to permanent monitoring within the framework of continuous quality assurance, during which the various influencing factors and production facilities are critically examined again and again. It goes without saying that we also constantly monitor the final products. To this end, a defined proportion of the products from the production line are tested rigorously in our laboratories on a daily basis.
