AI Technical Summary
Traditional single-magnetic lifting devices cannot automatically adapt to the center of gravity of irregularly shaped steel plates, resulting in poor lifting balance and a tendency to tip over; dual-magnetic lifting devices have a fixed magnetic pole spacing that cannot be adjusted, resulting in poor adaptability and applicability only to standard rectangular plates.
A beam-type movable permanent magnet lifting device was designed, comprising a permanent magnet lifter, a beam, and a pulley block. The pulley block can move flexibly, and the magnetic pole spacing can be adjusted by a limiter to adapt to the center of gravity of the plate and maintain balance.
This technology enables balanced hoisting of irregularly shaped steel plates, improves hoisting efficiency, avoids hook marks, and ensures appearance quality.
