These magnets are used to lift bundles of material with an irregular surface, which complicates lifting operations. Longitudinal magnets, however, have a particularly deep penetration field that makes them unsusceptible to such irregularities. This enable safe and effortless transport of bundles of material. Moreover, two or more of these magnets can be used, depending on the length of the bundles. In the event that people are present in the lifting area, however, extra mechanical slings must be fitted for safety purposes.
