Main Components
Core Structure Elements
The electromagnetic bridge crane consists of several integrated systems working together for efficient metal handling:
Crane Bridge: The main structural framework supporting all operational components, designed with double girder configuration for enhanced stability and load distribution.
Hoisting Trolley: Travels along the crane bridge, carrying the electromagnetic chuck and hoisting mechanism for vertical material movement.
Crane Traveling Mechanism: Enables the entire crane assembly to move along the workshop rails, providing complete area coverage.
Crane Cab: Operator control station providing direct visibility and control over all crane functions.
Electrical System: Comprehensive power distribution and control circuits managing all crane operations.
Electromagnetic System: Including the electromagnetic chuck, rectification control equipment, and cable connector – the core components for magnetic material lifting.
Working Principle
The electromagnetic crane utilizes electromagnetic principles to move steel objects. The electromagnet serves as the main functional component. When current flows through the system, the electromagnet generates a strong magnetic field that firmly attracts iron and steel materials, lifting them to designated locations. When the current is cut off, the magnetism disappears and releases the materials. This efficient lifting mechanism proves particularly valuable in scrap iron recycling and steelmaking workshops where continuous material handling is required.
Application Areas
Primary Industrial Applications
The QC series electromagnetic overhead crane serves multiple industries requiring efficient metal products handling:
Metal Scrap Yards: These cranes move and load/unload large quantities of metal scrap, streamlining recycling operations and material sorting processes.
Steel Mills: Essential equipment for handling raw materials including scrap metal and various steel products. The crane manages materials throughout the production cycle, from raw material intake to finished product dispatch.
Recycling Facilities: Used extensively for sorting and moving various material types, including iron, steel, and separating ferrous from non-ferrous metals.
Construction Sites: Facilitates movement and lifting of heavy materials such as steel beams and reinforcement bars, improving construction efficiency.
Automotive Manufacturing: Handles heavy machinery components including car bodies and engines during assembly processes.
Mining Operations: Assists in moving and lifting heavy materials including ore and mining equipment.
Ports and Shipyards: Manages steel cargo and heavy marine components during loading and unloading operations.
Power Plants: Supports maintenance activities requiring movement of large metallic components.
Product Features

- Power failure protection
- Over current protection
Operational Safety Guidelines
Load Handling: When the lifting electromagnet stops working or during rest periods, loads must be lowered to the ground rather than suspended.
Weather Conditions: During rainy and snowy weather, special attention to brake testing ensures reliable operation before commencing work. Lifting operations should proceed more slowly in adverse weather.
Personnel Safety: No personnel are permitted under suspended loads or standing beneath the crane during operation. The hook must never carry people, and standing on lifted objects is strictly forbidden.
Maintenance Requirements
Essential Maintenance Practices
Regular maintenance ensures optimal electromagnetic bridge crane performance and extends service life:
Cleanliness: Maintain clean oil, water, gas, and machine body conditions. Impure fuel causes oil leakage and potential oil circuit blockage. Low purity air and water affect heat dissipation and increase wear. Surface contamination leads to corrosion and unnecessary losses.
Supply Systems: Ensure sufficient oil, water, and air supply. Insufficient supply causes starting difficulties, poor lubrication, power reduction, severe wear, abnormal operation, and shortened service life.
Daily Inspections: Conduct regular safety inspections on crane components prone to problems. Operational vibrations can loosen bolts and nuts in fastening parts, requiring frequent inspection to prevent machine damage.
