Frequently Asked Questions (FAQs)

Frequently Asked Questions About Crane Lifting Magnet Factories in China

What materials are used in the construction of crane lifting magnets?

When it comes to building crane lifting magnets, high-quality materials are crucial. These magnets are typically made from structural steel, often sourced from European suppliers to ensure they meet European standards. The steel is machined using CNC machines and then welded together to create a robust and durable construction.

How are the magnets inserted and secured inside the lifting magnet?

After the outer construction is ready, the actual magnets are inserted. For permanent lifting magnets, multiple neodymium magnets are placed inside, along with a rotor that turns the magnet on and off. These magnets are secured with epoxide to ensure they stay in place. For electromagnets, a coil is inserted which gets magnetized when connected to a power source.

Can crane lifting magnets handle all types of metal?

No, crane lifting magnets are not suitable for all types of metal. They are designed to handle ferrous materials with good magnetic conductivity, such as steel. These magnets cannot pick up non-ferrous materials like stainless steel or aluminum.

What safety tests are performed on crane lifting magnets?

Safety is a top priority, and crane lifting magnets undergo rigorous testing. Each magnet must be able to safely carry at least three times its nominal capacity, which is tested through a pull-off test. Some manufacturers even simulate real-life conditions by inserting a piece of paper between the magnet and the lifting surface to account for air gaps and surface irregularities.

How long does the manufacturing process for crane lifting magnets typically take?

The manufacturing process for crane lifting magnets generally takes around 4-6 weeks. However, many manufacturers keep their most popular models in stock for quick delivery. Customized orders may take longer, as they require close collaboration between engineers and the sales department to meet specific customer needs.
