26.1 FOREWORD

Although some manufacturers offer a standard range of magnetic lifters, unlike other lifting equipment, they are not usually regarded as “general purpose” equipment. Magnetic lifters are usually employed in specific circumstances to lift specific loads. As there is no positive connection between the lifting device and the load, the ability of the magnetic lifter to safely lift a particular load needs to be carefully considered. This will normally involve tests to determine the lifting power of the magnet on the specific load.

Magnets will only work on a magnetic material which usually means a ferrous metal although some other materials such as cobalt or nickel are capable of being lifted magnetically.
