Effective protection of power supply cables and people in industry
In the automotive sector, OBO concentrates mainly on system construction and conveyor technology. Our focus is on chassis construction, meaning the wiring of machines or systems along the production lines. The electrical installation in chassis construction covers 75% of the overall installation. Powerful protection against footfall, dust and many other loads is essential for supplying the systems with power and data reliably. To meet these requirements, OBO offers the BKRS walkable cable tray system. The system is designed for the highest loads, which frequently occur in the vicinity of machines and automated production systems with robotic elements.
