The Double-Trolley Electromagnetic Hook Dual-Purpose Gantry Crane is a versatile heavy-duty lifting solution manufactured by Henan Mine, featuring two independent trolleys on a robust double-girner gantry structure—one equipped with an electromagnet for handling ferrous scrap, plates, coils, and billets, and the other with a standard hook for heavy individual loads such as machinery, containers, and structural components . This crane combines the space-saving L-type or U-type leg design (allowing trucks or rail cars to pass under) with the operational flexibility of dual-trolley configuration, enabling both trolleys to work separately for simultaneous material handling or synchronize for coordinated lifting of extra-long loads .

The electromagnet system includes a silicon-controlled rectifier converting AC to DC power, an emergency battery backup maintaining magnetic force for 10-30 minutes during power failures, and forced demagnetization for instant load release . Typical specifications include lifting capacity from (5+5) to (16+16) tons (magnet) and (5+5) to (50+50) tons (hook), spans from 10.5 to 35 meters, lifting heights from 6 to 30 meters, working duty class A6 to A8, and operating temperature from -20°C to +50°C .

It is widely used in steel service centers, scrap recycling yards, ports, and heavy manufacturing plants, improving material handling efficiency for both bulk steel and oversized items.

Core Applications – Double-Trolley Electromagnetic Hook Dual-Purpose Gantry Crane
1.Steel Mill Scrap Yards – Uses electromagnet to collect and sort loose scrap iron, shredded steel, and revert scrap from storage piles, while the hook lifts heavy scrap buckets, pig iron, and furnace charging boxes for electric arc furnace feeding .

2.Port & Terminal Steel Yards – Employs magnet to unload steel coils, plates, and structural steel from vessels or rail cars, while the hook handles heavy machinery, containers, and oversized cargo on the same dock without changing cranes .

3.Scrap Recycling & Processing Plants – Grabs mixed ferrous scrap with electromagnet for sorting and loading into shearing presses or balers, while the hook lifts heavy equipment, replacement parts, and processed scrap bales for shipment .

4.Steel Service Centers – Handles steel plates and coils with magnet for stacking and retrieval from storage racks, while the hook lifts heavy machinery, dies, molds, and finished product bundles for loading onto trucks .

5.Foundry Melt Shops – Uses magnet to transfer pig iron, cast iron returns, and heavy ferrous scrap to furnace charging areas, while the hook handles ladles, alloy additions, and heavy molds for cupola or induction furnace charging .

6.Railway & Heavy Equipment Maintenance – Employs magnet to collect scrap metal, rail offcuts, and metal waste from workshop floors, while the hook lifts locomotive engines, railcar bodies, wheelsets, and heavy components for repair and replacement .
