Core Technical Advantages
- 360° Precision Rotation for Full Coverage: Utilizing an upper-rotation drive structure with high-precision slewing bearings and variable-frequency motors, it achieves continuous 360° stepless rotation. Adjustable rotation speed ranges from 0.5 to 2 r/min with positioning accuracy of ±3 mm, effortlessly meeting multi-angle material alignment and precise workstation adaptation needs (e.g., 90° turning and cutting of steel plates in shipyards, multi-angle stacking of slabs in steel mills). The rotation mechanism incorporates dual braking protection, automatically locking upon positional completion to prevent accidental movement during operation and ensure safety.
- Intelligent Electromagnetic Adhesion: Dual Assurance of Safety and Energy Efficiency: The electromagnetic beam is equipped with a high-efficiency, energy-saving electromagnetic chuck. Utilizing copper-core coils and vacuum-poured insulation technology, it achieves Class H insulation with stable holding force and an annual decay rate below 0.5%. Features an intelligent power-off magnetic retention system that automatically switches to emergency power during sudden outages, maintaining magnetic force for at least 15 minutes (far exceeding national minimum standards) to prevent material drop. After stable material adhesion, it automatically switches to low-current maintenance mode, achieving 20%-30% energy savings compared to traditional electromagnetic chucks.
- High-strength structural design for heavy-duty applications: Main beams utilize Q345B/Q690 high-strength steel, optimized through finite element analysis and full annealing treatment to eliminate welding stresses, delivering 30% improved torsional resistance over conventional structures. The electromagnetic beam adopts a box-type beam structure with customizable lengths based on material dimensions. It supports multi-chuck grouped excitation control, with a single unit’s rated lifting capacity ranging from 5 to 50 tons. This enables one-time lifting and transport of various material specifications without manual strapping, boosting operational efficiency by over 30%.
- Intelligent Control Upgrade for Streamlined Maintenance: Utilizes a PLC + variable frequency control system supporting triple control modes—wireless remote, cab operation, and remote monitoring—for flexible adaptation to diverse work environments. Equipped with an intelligent fault diagnosis system that continuously monitors parameters including electromagnetic chuck status, rotation mechanism temperature, and motor load. Automatically alerts operators and pushes fault cause notifications during anomalies. Key electrical components feature IP55 protection rating, ensuring reliability in harsh conditions such as high temperatures, heavy dust, and high humidity.

Your Top Concerns About Henan Mine Machinery's Overhead Rotating Electromagnetic Beam Crane and Professional Answers
-
Will the electromagnetic chuck lose magnetism and cause material to fall during sudden power outages?Answer: Absolutely no loss of magnetism or material drop will occur, as our magnetic retention capability far exceeds national standards. Our equipment incorporates a dual power failure magnetic retention system: First, it features an independent emergency power supply that automatically and seamlessly switches over during sudden power outages, ensuring continuous power to the electromagnetic chuck. Second, it employs a “permanent magnet + electromagnetic” hybrid retention design. Even if the emergency power fails, the permanent magnets still provide stable holding force.
-
What is the maximum rotation angle achievable by the upper rotation mechanism? Will there be any shaking or positioning inaccuracies during operation?Answer: The upper rotation mechanism enables 360° continuous stepless rotation with precise positioning and smooth operation, eliminating swaying risks. Its core utilizes high-precision slewing bearings and variable-frequency drive motors, allowing precise rotation speed adjustment to prevent start-stop impact-induced sway. Dual protection from photoelectric positioning sensors and mechanical limit switches ensures positioning accuracy of ±3mm, fully meeting requirements for precise stacking and workstation docking.
