Application of Electro Permanent Lifting Magnets in Ship Building

Aug 28,2024

The shipbuilding industry is a multifaceted sector that involves numerous stages, from raw material preparation to final assembly. Efficient logistics and handling technologies are critical throughout this process. Electro permanent magnets, an advanced handling tool, play a significant role in both upstream and downstream applications within the shipbuilding industry. Let's explore how these tools are used across various stages.

Upstream Stage (Steel Mills and Suppliers)

1. Raw Material Handling: During the raw material processing phase, electro permanent magnets are invaluable for transporting materials such as steel plates. For instance, HVR's electro permanent magnets can effortlessly handle 20-ton steel plates with a thickness of 100mm, essential for shipbuilding. These magnets can also tackle challenges like lifting ribbed plates that traditional electromagnets struggle with.

2. Cutting and Loading: In the cutting and loading of plates, electro permanent magnets can easily manage individual steel plates. By integrating with automated equipment, these magnets enhance handling efficiency. HVR’s products offer features such as one-touch demagnetization and compatibility with PLC systems, which boosts production rates and meets the demand for automated workshops.

Midstream Stage (Shipyards)

1. Assembly and Welding: Electro permanent magnets are not only used for lifting individual steel plates but also for rotating and tilting multiple plates. This capability aids in precise positioning during assembly. The ability to automatically adjust and ensure only one plate is lifted at a time minimizes plate sticking and increases assembly efficiency.

2. Side Lifting and Handling: For steel plates requiring edge or tilted lifting, HVR offers specially designed side lifting electro permanent magnets. These magnets have a gripping force at least four times stronger than horizontal lifting, ensuring no slippage during side lifting operations.

Downstream Stage (Assembly and Maintenance)

1. Finished Product Handling: During the final stages of product handling, electro permanent magnets continue to play a crucial role. For example, HVR's products can be integrated with robotic arms for rapid clamping and movement of steel plates. This is particularly useful for welding, handling, loading, stacking, and disassembling tasks. HVR’s automation applications, such as the replacement of permanent magnets for curved panels, exemplify this use.

2. Remote Operation and Automation: For handling large outdoor steel plates, multiple electro permanent magnets can be used in tandem to facilitate remote operation. This approach accommodates variations in plate length and ensures smoother, safer, and more efficient handling operations.

Summary

Throughout the various stages of the shipbuilding process, HVR MAG's electro permanent magnets stand out for their powerful magnetic holding capacity, flexibility, and safety. These tools are instrumental in improving production efficiency and reducing costs. By incorporating electro permanent magnets, shipbuilders can enhance handling efficiency while ensuring safety and precision in operations.
