Metallurgy and steel mill cranes face extreme heat, abrasive dust, scale, vibration, and shock loading. Crane brakes in these environments must deliver stable torque at elevated temperatures, resist fade, and maintain mechanical integrity under harsh contamination. This often drives selection toward heavy-duty electro-hydraulic brakes with robust linkages, high-temperature-capable friction materials (commonly semi-metallic, sometimes sintered where appropriate), and designs that remain serviceable despite dust and scale.
Heat management is critical: dragging or undersized brakes quickly overheat, glaze linings, and damage brake wheels/discs. Components should have suitable seals, heat-resistant materials where needed, and protective covers where practical.
Maintenance access matters because downtime is expensive—choose designs with easy lining replacement and clear adjustment procedures. For critical cranes (e.g., ladle cranes), redundancy (dual brakes) and fail-safe architecture are often required. Always align brake specification with the crane’s duty class and the plant’s safety standard.
