FAQ
What is the difference between hook crane and magnetic crane?
A hook crane lifts various items of different shapes and materials using a mechanical hook, making it widely applicable. In contrast, a magnetic crane is equipped with an electromagnetic lifter, which can only lift ferromagnetic materials like steel. It is primarily used in steel mills, scrap metal handling, and similar environments. The main difference between the two is the type of lifting device and their suitable applications.
What problem is the electromagnetic crane going to solve?
The electromagnetic crane is designed to solve the problem of efficiently handling large volumes of magnetic metal materials. It enables fast, safe, and efficient loading, unloading, and transportation, reducing manual labor and significantly improving operational efficiency—especially in high-frequency tasks such as stacking, sorting, and loading.
What are the advantages and disadvantages of an electromagnetic crane?
Electromagnetic cranes offer high efficiency when lifting magnetic materials such as steel plates, billets, coils, and scrap. Their main advantages include quick pick-up and release of loads through electric control, reduced manual handling.
However, they also have limitations. They require a continuous power supply to maintain magnetic force—if the power fails, the magnet will lose its grip. To enhance safety, many cranes are equipped with magnet retention systems, such as battery-based backup, which help prevent accidental load drops during power outages. Additionally, they are not suitable for non-magnetic materials.
What is the difference between a magnet and an electromagnet?
A magnet is a general term that includes both permanent magnets and electromagnets. A permanent magnet produces a constant magnetic field without needing an external power source, while an electromagnet generates a magnetic field only when electric current flows through it. The key difference is that electromagnets require electricity to work and can be turned on or off, whereas permanent magnets always stay magnetized.
Will the crane with an electromagnet be safe?
Yes, electromagnetic cranes are generally safe when properly designed and maintained. They are equipped with various safety features such as overload limiters, anti-fall mechanisms, emergency stop systems, and limit switches to ensure stable and controlled operations. To address the risk of power failure, many cranes are fitted with battery-powered magnetic retention systems, which keep the magnetic force active for a period of time after a power outage, preventing the load from falling. Regular inspections and proper operator training also play a key role in ensuring overall safety.
