They ensure the transfer of the entire power supply system of a drivage or longwall workplace simultaneously with the advancement of that workplace. They are usually suspended on a monorail technological track and pulled by either additional hydraulic motors, or directly by a working machine (e.g. roadheader) connected to the system. This entire complex system significantly reduces idle times required for technological equipment transfers and increase productivity while reducing numbers of operating personnel. Systems include frames for safe placement and fixing of various types and kinds of transformation, switching and control technology. Furthermore, the system includes components for secure placement high and low voltage cables. Based on your needs and requirements we are able to offer specific solutions which we will process, manufacture and supply.
