Bi-Polar Lifting Magnets

Bi-Polar Magnet Ohio Bi-Polar Lifting Magnets do more than lift steel. They lift your profitability. These magnets handle finished and semi-finished steel slabs, structurals, coils or bundles. More importantly, they handle them without slinging, blocking and hooking operations. And Ohio Bi-Polar Lifting Magnets feature efficient, low-amp draw designs that cut energy costs every day. Add a price that is always reasonable and you're looking at today's superior value in lifting magnets.

Ohio provides a wide spectrum of standard and special bi-polar magnet designs with options to meet any application. These designs uniquely handle higher-temperature material than a standard rectangular magnet through a specially positioned magnet coil. A specially designed internal construction – just the right balance of wire to steel – develops maximum flux density for heavy-duty lifting with minimum power construction. Furthermore, Ohio’s bi-polar magnets use fewer square inches of magnet pole to contact the load, substantially reducing heat transfer and thus retaining maximum lifting capacity.
