At a major shipyard in Dalian, our electro permanent lifting magnet was implemented to streamline unloading and sorting of steel plates for hull construction. These plates range from 5mm to 50mm in thickness, with individual pieces weighing up to 10 tons. Previously, this work required multiple workers using traditional lifting equipment, such as slings, hooks and clamps.
The conventional steel plate handling process presented several issues: Each shift needed 3-4 workers coordinating operations, resulting in low efficiency and frequent production bottlenecks. Workers had to operate dangerously close to heavy plates, creating serious safety hazards. Additionally, manual stacking often resulted in uneven piles.
Now operators simply use a handheld remote to: Precisely unload plates from trucks, automatically sort by thickness and size, create perfectly aligned stacks in storage yards, and quickly retrieve specific plates when needed. The entire process is both safer and more efficient.
"The system has completely transformed our plate handling process," said the shipyard's logistics manager. "It's not only improved safety and efficiency but also given us much more precise inventory control of our steel plates."
The system only consumes power during magnetization/demagnetization, with minimal daily energy use. It works reliably on both clean and rusted surfaces, requires simple maintenance, and is compatible with existing crane equipment.
This case demonstrates how electro permanent magnet technology can optimize material handling in shipbuilding, addressing both efficiency and safety challenges. The system has become an indispensable tool for the shipyard's daily operations.
