This drawing is for a QC electromagnetic overhead crane, model QC 50t-22.5m-14m A8.
The crane is a double girder overhead crane with electromagnetic devices, built with a 50 ton lifting capacity. It is designed for metallurgical slag and steel scrap handling — loading, lifting, transporting, unloading, and lowering. The crane uses full VFD on all motions, and the operator works from an enclosed cabin control station. This is a demanding, heavy-duty application, so the hoisting mechanism is M8 class and the trolley and long travel mechanisms are M6 class.
This is a heavy duty electromagnetic overhead crane. The hook is fitted with a heavy duty magnetic chuck — model M-61DKM-180EMG-180-49M — suspended on the trolley hook. The magnet is heat resistant up to 500°C and water-wade capable, so it can handle hot slag and wet steel scrap without losing lifting force. This makes the crane suitable for metallurgical slag handling, steel scrap loading and unloading, and similar heavy industrial tasks. The working environment is high dust and non-explosion-proof, with an ambient temperature range of -40°C to +40°C.

Common questions about heavy duty electromagnetic overhead cranes, double girder overhead cranes with electromagnetic devices, overhead cranes with magnetic chuck, M-61DKM-180EMG-180-49M, metallurgical slag handling, steel scrap handling, 50 ton capacity, A8/M8 duty, full VFD, 500°C heat resistance, and water-wade operation.
A heavy duty electromagnetic overhead crane for metallurgical slag and steel scrap is a bridge crane with a heavy duty magnetic chuck instead of a standard hook. It grips ferrous materials with magnetic force and moves them through loading, lifting, transporting, unloading, and lowering cycles. This crane uses a 50 ton capacity double girder structure and a heavy duty magnetic chuck M-61DKM-180EMG-180-49M suspended on the trolley hook. The magnet is heat resistant up to 500°C and water-wade capable, so it can handle hot slag and wet steel scrap without losing lifting force.
M-61DKM-180EMG-180-49M is the heavy duty magnetic chuck model used on this crane. The "M" prefix indicates a magnetic chuck. The "61" and "180" refer to the magnet diameter and coil configuration. "EMG" indicates the electromagnetic series. "180-49" refers to the magnet dimensions and pole configuration. This model is selected for metallurgical slag and steel scrap handling because it provides strong holding force on irregular and heavy loads, and it is built with heat resistant insulation up to 500°C and water-wade protection for wet or humid conditions.
A8 is the overall duty class for the crane, which means very heavy duty and continuous operation. The hoist mechanism is M8 class because lifting and lowering are the most heavily loaded motions in metallurgical slag and steel scrap handling. The trolley and long travel mechanisms are M6 class, which is still heavy duty but slightly lighter than M8. This combination matches the actual working pattern of a scrap handling crane: long lifting cycles with frequent travel moves. Using different mechanism classes where appropriate keeps the crane reliable without over-specifying every motion.
Full VFD (variable frequency drive) on the hoist, trolley travel, and long travel gives smooth acceleration and deceleration, precise load positioning, and lower mechanical wear. For metallurgical slag and steel scrap handling, the load is heavy, irregular, and often hot or wet. VFD lets the operator position the magnet accurately over the scrap pile, lift without shock loading, and set the load down cleanly. The speeds in this drawing — minimum hoisting 7.55 m/min, trolley 43.5 m/min, long travel 100 m/min — are all achieved with VFD control, and the VFD also allows slow, controlled motion when the magnet is close to the load.
Metallurgical slag can be hot when it is handled, and steel scrap is often stored or processed in wet conditions. The 500°C heat resistance means the magnet coil, insulation, and housing can handle hot slag without losing magnetic force or damaging the winding. The water-wade capability means the magnet and its cable system can operate in shallow water or wet conditions without short circuits or insulation failure. Together, these features make the crane suitable for demanding scrap yards, slag pits, and steel mill environments where heat and water are both present.
3-phase, 380 V, 50 Hz is the standard supply for this crane. This covers the hoist motor, the trolley travel motor, the long travel motors, the VFD drives, and the cabin control system. The heavy duty magnetic chuck M-61DKM-180EMG-180-49M and its control system also operate on this power supply, usually through a separate magnet controller panel with battery backup or capacitor buffer to maintain holding force for at least 30 minutes after power failure. The electrical quotation for the electromagnet system is handled separately.
High dust means the working environment has a lot of airborne dust from slag, scrap, and steel processing. The electrical equipment, motors, and control panels are specified with appropriate protection (such as IP54 or higher) to keep dust out and maintain reliable operation. Non-explosion-proof means the environment is not classified as a hazardous area with explosive gases or combustible dust, so the crane does not need explosion-proof motors or enclosures. This keeps the crane simpler and more cost-effective for the actual site conditions. If your site does require explosion-proof equipment, Yuantai can supply it as a customized option.
Key safety features for heavy duty electromagnetic overhead cranes handling metallurgical slag and steel scrap include: battery backup or capacitor buffer to maintain holding force for at least 30 minutes after power failure; heat shielding between the magnet and the load to protect the coil; water-wade protection for the magnet and cable system; swivel-type mechanical suspension to prevent cable twist; armored flexible cable rated for high temperature and crane trailing applications; and residual magnetism release to ensure clean material drop. For this crane, the M-61DKM-180EMG-180-49M magnet is built with these features, and the full VFD control helps prevent load swing and shock loading.
