20 Tons Electromagnetic Suspension Overhead Crane

Der 20 tons electromagnetic suspension overhead crane integrates advanced electromagnetic suspension technology with reliable overhead crane design, delivering exceptional performance, Präzision, and safety for industrial material handling. Specifically engineered to handle loads up to 20 Tonnen, this crane is tailored for scenarios requiring efficient, contact-free lifting and transportation of ferromagnetic materials, addressing the limitations of traditional lifting equipment and setting a new standard in heavy industry operations.

20 Tons Electromagnetic Suspension Overhead Crane

20 Tons Electromagnetic Suspension Overhead Crane Core Technology & Working Principle

The crane adopts electromagnetic suspension (EMS) Technologie, which leverages the attractive force between electromagnets and ferromagnetic tracks to achieve contact-free suspension and movement. Unlike traditional overhead cranes that rely on wheels and rails with physical contact, this crane’s trolley and lifting mechanism suspend stably above the track through a precisely controlled magnetic field, eliminating friction between moving parts. The electromagnetic system generates a strong magnetic force when energized, securely adsorbing ferromagnetic materials such as steel plates, billets, Altmetall, and steel coils, while enabling smooth, precise lifting, Senkung, und horizontale Bewegung. A high-precision closed-loop control system dynamically adjusts the current in the electromagnet coil to maintain a stable suspension gap, ensuring consistent performance even during heavy-load operations.

Electromagnetic Suspension Overhead Crane Key Features & Vorteile

20 Tons Electromagnetic Suspension Overhead Crane

• ◆ Superior Load Capacity & Präzision: With a rated load of 20 Tonnen, the crane is capable of handling heavy ferromagnetic materials with exceptional stability. The electromagnetic suspension design eliminates mechanical friction, reducing vibration and ensuring precise positioning—critical for applications requiring high accuracy, such as mold handling, steel plate stacking, and precision component transportation. The adjustable magnetic force allows for safe handling of irregular or layered materials, minimizing material damage.
• ◆ Enhanced Safety & Zuverlässigkeit: Equipped with a power-off magnetic holding function, the crane retains magnetic force even in the event of sudden power failure, preventing loads from dropping and minimizing accident risks. Additional safety features include overload alarms, Not-Aus-Systeme, and anti-sway technology, ensuring safe operation in high-intensity industrial environments. The contact-free design reduces wear and tear on mechanical components, extending the crane’s service life and reducing maintenance costs.
• ◆ High Efficiency & Energy Saving: By eliminating friction between moving parts, the crane operates with lower energy consumption compared to traditional overhead cranes. The electromagnetic lifting system eliminates the need for manual rigging or slings, reducing operational time by up to 40% and significantly improving handling efficiency. It supports continuous 24-hour operation, making it ideal for high-volume production scenarios such as steel mills and scrap recycling facilities.
• ◆ Flexible Operation & Adaptability: The crane offers multiple control modes, including pendant control, kabellose Fernbedienung, and cabin operation, adapting to different working environments and operator preferences. It can be customized with different electromagnetic chuck configurations—such as rectangular, circular, or extended beams—to suit specific materials, including high-temperature steel, thin plates, and irregular scrap metal. The crane’s robust steel structure and IP65-rated magnet assembly ensure dustproof, wasserdicht, and corrosion-resistant performance, suitable for harsh industrial conditions with ambient temperatures ranging from -20°C to +180°C.
