In contrast, this very simple example of a bracket was attached to the top of a sandwich panel.  This fixed to the centre of the inner skin, but allowed lifting over the centre of the combined section.  This type also allows 4 lifting inserts to be used whilst only requiring 2 ropes.  This allows smaller capacity inserts to be used and minimises the need to thicken up the section.

The more usual type of lifting bracket is an ‘L’ or ‘C’ bracket. An ‘L’ bracket allows ‘flat’ panels to be lifted without lifters in the top face. A ‘C’ bracket will similarly allow a panel with an overhanging top to be lifted from the face without the need for a lifting device in the top face.

These brackets take a lot of stress, and for this reason they have to be fully designed.  In addition they must be tested and marked with a safe working load (SWL).  If there are limitations on their use, i.e. pitching, turning, vertical only etc, then this must also be marked.   

Access should always be checked to make sure that the bracket can be unbolted and removed safely after erection of the panel.  Close co-ordination with the erection company is vital.
