حل ذكي للرافعة العلوية الكهرومغناطيسية لورشة العمل المتدحرجة لمناولة المواد

Lianyuan Steel Overview

Lianyuan Steel, a major state-owned enterprise under the Fortune Global 500 Hunan Steel Group, has an annual production capacity of over 12 million tons. As a leading high-quality steel production base in Central and Southern China, it operates the world’s largest medium and thin-gauge heat-treated plate production line. Its silicon steel base metal output also ranks first in China, with products widely used in landmark projects such as the Hong Kong–Zhuhai–Macao Bridge and Tesla.

To upgrade material handling operations in its rolling workshop, Lianyuan Steel introduced DAFANG’s رافعة علوية كهرومغناطيسية, achieving a significant step toward smart, efficient, and safe steel logistics. Equipped with electromagnetic lifting technology, laser positioning, and an intelligent monitoring platform, the system has greatly enhanced operational efficiency and workplace safety, supporting the steel industry’s move toward standardized and intelligent crane operations.
