The permanent magnetic lifters are in a small design and are manufactured by the best Permanent Magnetic Lifter Manufacturers in India, Magna Tronix. Our designs are more in line with products from other countries. The independent permanent magnet never runs out of holding power. The quality of the magnets utilized in our lifters is excellent. There are no dangling cables or switches needed because these lifters do not require an external electric supply. The safety handle's "ON - OFF" position regulates the permanent magnet's field. There is no risk of an accident because of an electrical supply outage. For lifting magnets to lift as much as possible, the surface must be in good shape. The best surfaces are those that have been ground or machined, but a forging, casting, or other well-clean surface will also function as long as there is enough flat space for the magnet to make contact with the work piece. For clean, flat ferrous plates that have been ground and de-rated by a factor of three, lifting capacity is advised. Because of factors including material thickness, alloy content, surface condition, and contact area, a safety factor is necessary. In extreme cases, the safety factor may need to be raised.
