Metallurgical cranes operate by longitudinal movement along the factory track direction, lateral movement of the trolley, and lifting movement of the hook. They are applicable to metal smelting workshops and are special cranes for lifting molten metals that comply with the standards of JB/T7688.1-95 and JB/T7688.15-95. The application of metallurgical cranes is generally suitable for an ambient temperature ranging from -10°C to +50°C. The relative humidity does not exceed 50% at a temperature of 40°C, and the radiant temperature of the molten metal lifted on the forging hook and plate hook does not exceed 300°C. Working levels: A7 and A8 are used in relatively busy metallurgical foundry workshops.
Metallurgical cranes are mainly special cranes applicable to metal smelting, rolling and hot processing, etc. These include open-hearth charging bridge cranes, ground charging cranes, hopper cranes, ingot stripping cranes, full-mold cranes, cover uncovering cranes, clamp cranes, slab turnover cranes, forging cranes, charging and discharging cranes for heating furnaces, hopper – electromagnetic cranes, and hopper – grab cranes.
