It is also known as permanent lifting magnets, these magnets have an on/off handle to engage and release the magnet. They have a lifting eye for attaching a hook or sling. It’s handles lock in both the on and off positions to prevent accidental release.
1, Powerful: High capacity(up to around 10000Kg), even with a big air gap.
2, Safe: an on/off handle to engage and release the magnet.
3, Low weight: Detachment strength from 70 to 110 times its weight, can be incorporated in any type of crane mechanism.
4, Maintenance: The contact magnetic poles can be rectified frequently.
5, Comfortable: Magnetisation can be activated with one hand.

1, Contact Surface: When there are any air gap between the lifter and the object that is to be lifted, the magnetic flux is obstructed, thereby reducing the magnetic pulling force. Gaps are caused by various objects (oils, paints, oxidation or rough surface).
2, Thickness: Magnetic flux of lifter requires a minimum material thickness during working. When the material which has to be lifted doesn’t have a minimum thickness, the magnetic attraction strength will decreases considerably .
3, Material: As we know steels low in carbon are good magnetic conductors, however, those with a high percentage of carbon or alloy with another material, loose magnetic properties.
Note: Capacities listed are based on lifting rigid, flat metal which has a clean and smooth surface. If used on dirty, thin, oily or curved surfaces, the capacities will be reduced. Do not use on metal that flexes.
Warning: Don’t use to lift people or items over people.
