The Large Ball Magnet for Heavy - Load Lifting is a robust, industrial-grade magnetic component designed to tackle the demanding task of lifting and moving heavy ferrous objects in construction, manufacturing, scrap metal processing, and logistics. With diameters ranging from 60mm to 200mm (and custom sizes available for extreme applications), this oversized spherical magnet is engineered for maximum strength and durability. Crafted from high-grade neodymium (typically grade N45 or higher) or samarium cobalt (for high-temperature resistance), it delivers exceptional holding forces—from 100kg to over 1,000kg—capable of lifting steel beams, iron plates, scrap metal piles, and other heavy loads with ease.

A key design feature of the Large Ball Magnet for Heavy - Load Lifting is its reinforced structure. Unlike smaller ball magnets, which rely on their material strength alone, large ball magnets for heavy lifting are often encased in a thick steel or aluminum shell. This shell serves two critical purposes: first, it protects the fragile neodymium core from impact, abrasion, or damage during heavy use (such as when the magnet is dropped onto a pile of scrap metal). Second, the steel shell acts as a magnetic conductor, concentrating the magnetic field at the point of contact with the load and reducing magnetic leakage—significantly boosting the magnet’s effective holding force. For example, a 150mm neodymium ball magnet encased in a steel shell can lift up to 800kg of steel, compared to 500kg for an unencased magnet of the same size.

Another advantage is its versatility in lifting irregularly shaped loads. The spherical shape of the magnet allows it to make contact with uneven or curved surfaces—such as the rounded edges of steel pipes or the jagged surface of a scrap metal pile—more effectively than flat magnets. This ensures a secure grip, even when the load’s surface is not perfectly flat. In a scrapyard, for instance, a crane equipped with a 200mm large ball magnet can easily lift and move a pile of mixed scrap metal. The magnet’s spherical shape conforms to the irregular surface of the pile, creating multiple points of contact and distributing the load’s weight evenly, reducing the risk of slippage.

Safety is a top priority in heavy-lifting applications, and this magnet is designed with multiple safety features. Many models include a built-in release mechanism, such as a manual lever or electromagnetic coil, that allows operators to disengage the magnet from the load safely. This is crucial for precise placement of heavy objects—like positioning a steel beam during building construction—where accidental release could cause damage or injury. Additionally, the steel shell is often equipped with lifting eyes or hooks that allow for secure attachment to cranes, hoists, or other lifting equipment, ensuring the magnet and load are stable during transport.

Durability is also enhanced by specialized coatings and treatments. The steel shell is typically coated with a layer of epoxy or powder coating to resist corrosion, rust, and wear—essential for outdoor use in construction sites or scrapyards where the magnet is exposed to rain, snow, or saltwater. The neodymium core is protected by a nickel-copper-nickel coating, which prevents oxidation and maintains magnetic strength even in harsh environments.

In manufacturing facilities, the Large Ball Magnet for Heavy - Load Lifting is used to streamline material handling processes. For example, in an automotive factory, a 100mm neodymium ball magnet can be mounted on a robotic arm to lift and move heavy metal chassis components between assembly stations. The magnet’s strong force ensures the component stays securely attached, while its spherical shape allows for easy alignment with the robotic arm and the assembly line.

Whether used in construction, scrap metal processing, manufacturing, or logistics, the Large Ball Magnet for Heavy - Load Lifting delivers the strength, versatility, and safety needed to handle the heaviest loads. Its robust design and exceptional performance make it a valuable asset for any industry that requires efficient, reliable heavy-lifting solutions.
