It can be a costly business for scrap firms when metal fragments damage the tyres of vehicles operating in the yard. To this end, Eriez Magnetics Europe has developed a Magnetic Sweeper which, once attached to a vehicle tow bar, uses its high-strength magnetic field to pick up and hold nails, wire, welding rod ends, bolts, ferrous chips and all kinds of potentially damaging pieces of metal - all in one sweep.
