Mar. 2008: Salzgitter Flachstahl GmbH, the largest steel subsidiary in the Salzgitter Group, produces about 4.6 million tonnes of steel each year. With its extensive investments in new plant technology, Salzgitter Flachstahl guarantees compliance with all quality standards into the future. The company also sets the highest standards of safety for its workers while simultaneously maintaining high workflow efficiency. For this reason, potential crane collisions must be recognised and avoided without exception.
An automatic anti-collision system is to guarantee complete protection from collisions. The redundantly designed system should deliver constant position data in the close-up range, including data monitoring at any distance between the individual cranes in the input stock area of the hot strip mill. GIPA mbH, the company commissioned to implement the project, uses Symeo LPR sensor technology to ensure absolutely fail-safe operation.
LPR sensors attached to gantry and overhead travelling cranes provide paired measurements of their relative distance and speed to one another at rates of up to thirty times a second. Two sensor pairs enable redundant measurements, ensuring maximum data quality and fail-safe collision avoidance. The projectís success up to now and the fail-safe anti-collision system are convincing: Symeo sensor technology will be used to upgrade additional cranes.
