Steel Coils, Cranes, Wireless, and PROFINET

& filed under , .

Automakers are buying huge volumes of high-strength steel as they attempt to build solid, lightweight cars. Annealing and galvanizing plants throughout the Midwest process these thin steel sheets, creating steel coils that weigh up to 40 tons.

Hoisting and moving these huge coils through the plant is no simple task, it requires large bridge cranes that are precisely controlled. When multi-ton loads are being moved, slips, bumps and drops can’t be tolerated. Accidents can have grave impact on nearby personnel, equipment and infrastructure.

They used Wireless Access Points connected via Ethernet cabling and powered via PoE.  They communicate back to plant’s SCADA system as well as bring the video signals to the control room and DVR, all via Profinet
