Misconceptions

Misconception 1. If you have attended a training course you are a competent rigger.

Training is only one part of being competent to carry out your job, you must also be adequately qualified and have sufficient experience.

Read Details

Misconception 2. Magnets can be used for lifting all types of steel.

The effectiveness of a magnet changes depending on the type of steel it is used with. Ratings can change depending on the type of material. Or the magnet may not be able to pick up the type of material.

Read Details

Misconception 3. Magnets can be used on any thickness of material.

The thicker the material the magnet lifts is generally better. Most magnets are restricted to a minimum thickness of material they can lift. 

Read Details

Misconception 4. A Magnets capacity is constant for different material sections, i.e. round bar, flat plate etc.

A Magnet can lift a significantly heavier flat plate than a round bar, if it is capable of lifting both types of material. Many magnets may only be capable of lifting one type of material. Consult manufacturer for any restrictions that may apply.

Read Details

Misconception 5. Material surface condition will not affect the magnets capabilities.

The surface of both the magnet and the object being lifted must be clean, if not the flow of the magnetic field between them will be affected and reduce the capacity of the magnet and could result in loss of the load.

Read Details

Misconception 6. Magnets can be used for lifting at angles.

Care must always be taken to ensure the load is evenly distributed. Magnets should not be used for side pulling or sliding the load.

Read Details

Misconception 7. Magnets can be energised prior to contacting the load.

It is not a good practice to have the magnet energised before making contact with the load as the energised magnet can collect magnetic debris before contacting the load and create an air gap which will reduce the capacity and efficiency of the magnet

Read Details

Misconception 8. Magnets can lift loads that are flexible.

As the length or width of the load increases the load begins to deflect and to peel at the magnet face, this can create an air gap which reduces the capacity of the magnet.
