The Metallurgical Gantry Crane is a specialized heavy-duty lifting solution manufactured by Henan Mine, engineered for high-temperature, harsh-environment operations in non-ferrous and ferrous smelting plants, steel mills, and foundries to handle molten metal ladles, hot slag, copper slag, and other high-temperature materials .

This crane features a robust double-girder box-type or truss gantry structure with U-shaped or L-shaped legs to improve ladle passing capacity, redundant safety systems including strong wind alarms, anti-break shaft devices, anti-tipping devices, and overload protection, and is designed with comprehensive heat-radiation protection including fireproof panels and insulation layers at the bottom of main beams, trolleys, and driver's cabins .

The crane meets international standards including JB/T 7688.1-2008 for metallurgical overhead cranes and JB/T 7688.5-2012 for foundry cranes, with typical specifications including lifting capacity from 32 to 320 tons (customizable up to 500 tons), spans from 6 to 24 meters, working duty class A6 to A8, and ambient temperature range from -10°C to +50°C with heat-radiation resistance up to 300°C . The crane integrates PLC control, variable frequency drive for smooth operation, electric intelligent anti-sway systems, redundant control technology at key positions (electrical control, limit position, overload), and optional safety monitoring systems for real-time operational data and fault diagnosis .

The Metallurgical Gantry Crane is designed for high-temperature and heavy-duty lifting operations in steel mills, foundries, and smelting plants. It features double girder construction, heat-resistant insulation, spark protection, dual braking systems, and overload protection to safely handle molten metal, ladles, steel billets, slabs, coils, and scrap materials. This crane is widely used for charging furnaces, pouring molten metal, transferring hot ingots, and handling raw materials in extreme conditions. Typical specifications include lifting capacity from 5 to 200 tons, span from 10.5 to 31.5 meters, lifting height from 6 to 20 meters, duty class A6 to A8, power supply 380V/50Hz three-phase AC, and ambient temperature range from -20°C to +60°C.

Core Applications – Metallurgical Gantry Crane
1.Non-Ferrous Smelting (Copper, Aluminum, Lead, Zinc) – Handles and transports molten metal slag ladles (e.g., copper slag at 1200°C+) from furnaces to cooling areas, with U-shaped leg design allowing trains to operate within the span for direct slag unloading and loading .
2.Ferrous Steel Mill Slag Handling – Lifts and transfers hot steel slag pots from basic oxygen furnaces or electric arc furnaces to slag processing yards, with heat-resistant construction and anti-radiation protection for high-temperature slag handling .
3.Molten Metal Transfer – Transports liquid steel or iron ladles from melting furnaces to continuous casting machines, teeming platforms, or foundry molds, with fixed-spacing hooks on the main trolley for ladle lifting and independent auxiliary trolley for tilting operations .
4.Furnace Charging & Scrap Handling – Charges furnaces with scrap steel, pig iron, DRI (direct reduced iron), and alloy materials using magnetic or grab attachments, serving in both indoor and outdoor environments at steel plants and foundries .
5.Metal Rolling & Thermal Processing – Handles red-hot steel slabs, billets, blooms, and coils from continuous casting to reheating furnaces or rolling mills, with anti-radiant heat protection for the bottom of main beams and driver's cabins .
6.Heavy Equipment Maintenance – Lifts and replaces large metallurgical equipment such as converter trunnion rings, furnace shells, ladle turrets, and electrode columns during plant shutdowns and major repairs, with heavy-duty A7-A8 classification for continuous high-cycle operations .
