Hot Strip Mill-2 (HSM-2) of SAIL, Rourkela Steel Plant has successfully implemented an innovative anti-collision alarm system for its Electric Overhead Travelling (EOT) cranes in the slab yard, effectively addressing a critical safety challenge. These systems have effectively mitigated the risk of crane collisions on the same level.
Previously, Crane 3 and Crane 5 operated on different DSL levels, with their work zones overlapping and posing a collision risk. Past incidents, including significant machinery damage, highlighted the need for a solution to prevent such accidents. In response, the HSM-2 Electrical Crane Group developed an in-house anti-collision alarm system designed to detect and alert operators of potential risks.
The system, which uses a combination of photo sensors and RF transmitters and receivers, monitors Crane 3’s movements as it enters the work zone of Crane 5. When a potential collision is detected, synchronized audio and visual alarms are triggered in both operator cabins, ensuring timely action to avoid accidents.
With the system’s real-time alerts, crane operators can now work with heightened awareness, reducing human error and preventing costly collisions. The successful implementation of the system has eliminated the risk of accidents between Crane 3 and Crane 5, enhancing both safety and operational efficiency at HSM-2.
The New System was inaugurated by Mr. Subrat Kumar, CGM, (HSMs and Aux) in the presence of Mr. R. K. Muduli, CGM, (Electrical), Mr. Abakash Behera, GM (Safety) and other Senior Officers of the plant. The project was led by Mr. R. Kujur, GM and HOS, HSM-2 (E), Mr. S. Soren, GM, HSM-2 (E) and Mr. Tribikram Seth, Senior Manager, HSM-2 (E) under the guidance of Mr. Subrat Kumar and Mr. R. K. Muduli. The implementation was done by Mr. R. K. Panda, Mr. S. Mallick, Mr. K. C. Adha and their team. The in-house solution has significantly minimized operational disruptions, structural damage, and costs, setting a new standard for safety in crane operations.
