Frequently Asked Questions (FAQs)

What are the key parameters to consider when selecting a crane magnet for lifting steel plates?

When selecting a crane magnet for lifting steel plates, several key parameters need to be considered. These include the size of the steel plate (length, width, and thickness), the number of steel plates to be transported at one time, and the type of material being lifted. For instance, the magnetic lifting system needs to be customized based on the thickness of the steel plates, with thinner plates requiring adjustments to the magnetic flux to ensure safe and efficient lifting. Additionally, the configuration of the overhead crane, such as whether it is a single beam or double beam and its loading capacity, is crucial for ensuring compatibility and safety[1][2][4].

Can crane magnets handle stainless steel or other non-ferrous materials?

Crane magnets are generally not suitable for lifting stainless steel or other non-ferrous materials because these materials do not have good magnetic conductivity. Magnetic lifting systems are specifically designed to handle ferrous products, such as steel plates and pipes, where the magnetic field can effectively interact with the material. For non-ferrous materials, alternative lifting solutions like vacuum lifting systems may be more appropriate, although they come with their own set of limitations and safety concerns[2][4].

How do you ensure the safety of the load during power outages or failures?

To ensure the safety of the load during power outages or failures, electro-permanent magnets (EPMs) are often preferred over traditional electromagnets. EPMs generate a magnetic field using permanent magnet materials that are activated and deactivated by brief electrical pulses. Once magnetized, the lifting force of EPMs remains even in the event of a power failure, preventing the load from dropping. This makes EPMs much safer and more reliable in critical lifting operations[5].

What is the minimum thickness of steel sheets that crane magnets can lift?

The minimum thickness of steel sheets that crane magnets can lift varies depending on the specific magnet system. However, most advanced magnetic lifting systems can handle steel sheets as thin as 2mm. For such thin sheets, the magnetic lifting system must be carefully customized to ensure that only one sheet is lifted at a time and to prevent the magnetic field from weakening due to air gaps or the sheet’s thinness[2][4].

What kind of maintenance and inspections are required for crane magnets to ensure longevity and safety?

To ensure the longevity and safety of crane magnets, regular inspections and maintenance are essential. This includes scheduling periodic checks by qualified technicians to assess the condition of the magnet and identify any potential issues. The inspections should focus on detecting wear and tear, damage, or any maintenance requirements that could affect the magnet’s performance. Additionally, ensuring compliance with safety standards such as EN 13155:2020(E) and CE standards is crucial for maintaining the quality and reliability of the lifting magnets[1][3][4].
