Electromagnetic overhead crane

The electromagnetic overhead crane is a specialized lifting device designed for handling magnetic ferrous metals, such as steel plates, billets, bars, and scrap materials. Its basic structure is similar to that of a conventional hook-type overhead crane, but it is equipped with a powerful DC electromagnetic chuck suspended from the hook. This magnet provides strong magnetic force to lift and transport metal materials efficiently and safely.

The system uses a thyristor DC control box installed in the driver’s cab, which converts AC power into stable DC power for the electromagnetic chuck. The power is transmitted through a dedicated cable reel mounted on the trolley, ensuring reliable current supply during crane movement. When the power is turned off, the magnetic field disappears instantly, allowing for quick and controlled material release.

With smooth operation, precise control, and strong lifting capacity, the electromagnetic overhead crane is widely used in steel mills, shipyards, scrap recycling yards, and warehouses. It greatly improves handling efficiency, reduces manual labor intensity, and enhances workplace safety. Its robust structure and intelligent control system make it an ideal choice for continuous heavy-duty operations in metal processing industries.
