ZOMAX electromagnetic overhead crane is a heavy-duty, high-speed crane that uses electromagnetic technology to complete the lifting, moving and stacking of electromagnetic materials such as scrap iron, scrap steel, steel coils and steel plates.
The crane spreader is available in two configurations: one featuring a hook with a lifting magnet and the other equipped with a magnetic lifting beam, depending on the specific material handling demanding.The magnetic lifting beam can be customized as a non-rotating beam or a rotating beam to accommodate various operational needs. In the event of a power outage or system failure, the electromagnetic force can last 10 to 30 minutes to prevent the immediate release of lifted materials.
A magnetic bridge crane, also known as an electromagnetic crane, is designed for lifting and transporting metals such as steel. It operates using electromagnetic technology and can be equipped with two types of lifting devices: a hook fitted with a lifting magnet or a magnetic lifting beam (either fixed or rotatable), allowing it to handle different material-handling needs.
Magnetic bridge cranes are widely used in recycling plants and scrap yards. They work by generating a magnetic field through electric current flowing around coils surrounding the magnet. The current controls the magnet’s on/off state as needed. When power flows through the electromagnet—which consists of wound wire coils and an iron core—it produces the magnetic force required for lifting.
Highly Efficient for Handling Ferrous Materials
One of the greatest advantages of magnetic cranes is their ability to easily manage ferromagnetic materials. Whether lifting steel coils, plates, or scrap metal, the magnets provide a secure grip, significantly reducing the risk of materials slipping or falling.
Enhanced Safety
Because the magnets firmly hold the load, the chances of accidents caused by slings, hooks, or other traditional lifting tools are greatly minimized. Operators can control the lifting and releasing processes remotely, reducing manual handling and limiting exposure to hazardous environments.
Increased Productivity
Electromagnetic bridge cranes can pick up and release loads without manual intervention, speeding up the entire material-handling process. A single crane can lift multiple pieces at once, cutting down on idle time and improving overall operational efficiency.
Versatile and Precise
The ability to switch electromagnets on and off provides precise control during lifting. This allows operators to gently move single items or lift multiple pieces at once, depending on the operational needs.

Electromagnetic Suction Cup: A core component that absorbs and transports ferromagnetic metals by converting AC to DC power and transmits it via a dedicated cable drum to power the suction cup ,enabling the lifting of heavy objects.
Bridge, Crane Operating Mechanism, Trolley, and Electrical Equipment: These components form the crane’s structure, with the bridge supporting the crane, the operating mechanism moving along the bridge, the trolley running on the main beam, and the electrical equipment controls the crane’s operation and safety functions.
Rotating Structure: Some designs include a rotating structure, allowing the crane to perform 360-degree rotation for enhanced flexibility and efficiency.
Working Principle: The crane lifts objects using electromagnetic force. The suction cup generates magnetism to lift the object, and after moving it to the desired location, the power is turned off, releasing the load.
Steel Manufacturing
Electromagnetic bridge cranes are indispensable in steel mills, where they are used to move large steel products such as steel plates, blooms, coils, and bars.
Metal Processing and Manufacturing
In metal processing and manufacturing plants, electromagnetic bridge cranes are used to lift and transport metal sheets, coils, or plates, which are typically used in the production of various components.
Scrap Metal Recycling
In scrap metal recycling yards, electromagnetic cranes play a crucial role in lifting and sorting ferrous scrap metal. Their ability to handle scrap metal of different sizes and shapes makes these cranes highly efficient in recycling operations.
Warehouse and Storage Operations
Electromagnetic cranes are also widely used in warehouses and storage yards to efficiently manage and store metal products. Their capability to lift and move heavy metal products reduces labor costs and enhances operational efficiency.

Before purchasing, calculate the typical load weight (steel plates, billets, coils, scrap bundles, etc.) and the maximum peak load. Also consider working hours per day, cycle frequency, and whether the crane will run continuously. Choose a magnet and crane system designed for heavy-duty, frequent lifting if your operation involves long shifts (like steel mills or scrap yards). A properly matched duty cycle prevents overheating and extends magnet lifespan.
Confirm magnet type based on material shape, thickness, temperature, and surface conditions.
For steel plates → rectangular electromagnets
For scrap metal → circular magnets
For steel coils → magnet + special coil lifting beam
Choose cranes with battery-backup systems, dual power supply, or fail-safe magnet controllers. These systems maintain magnetization for several minutes after a power cut, ensuring operators can safely lower the load.
Check whether the magnet requires DC power from a rectifier, voltage level, and cooling requirements. Modern cranes use intelligent magnet controllers with features like:
Overheat protection
Stepless magnetization adjustment
Energy-saving modes
Make sure the system matches your plant’s electrical standards and can integrate with your existing overhead crane controls.
If lifting billets, slabs, or hot castings, choose a high-temperature-resistant magnet (usually 300–600°C durability). Request technical sheets showing temperature resistance and insulation class.
Choose modular designs where magnets, beams, or controllers can be swapped or upgraded. This allows the crane to handle new materials (coils → plates → scrap) without buying a new system.
