On September 18, 2019 a training of lifting and feeding technology was held for the global operator of galvanizing plants, which mainly uses Stahl lifting technology on a large scale. The training also included energy supply systems of enclosed trolleys, energy chains and winding drums. This technique is widely used in galvanizing plants and the reliability of this technology significantly affects the operating costs of the galvanizing technology. Particularly in the context of demanding environments and the high degree of utilization of the technology being operated, any upgrading of the skills of maintenance personnel is a significant element that can significantly increase the reliability of the technology being operated.
