We have a 20+ tonne load to move and the original lugs have been removed (years ago) and we need to lift the 'chamber' away from its location. Having looked at PUWER / LOLER I can determine that as we are adapting the 'work equipment' e.g. installation of a new lug, it has to be suitable for its intended use. Furthermore, LOLER looks at strength and stability and that they are fit to use on the load (potentially multiple points) and that the point of connection to the load, that these points are also suitable and of adequate strength for use in a lift. Lifting lugs attached to a load need to be risk assessed for being suitable and sufficient for the lift - who can make this call and who can test at site?
I am approaching a competent 'rigger' to look at how they would rig the load, but need advice on how best to progress. The lift is evident to move the chamber away for full maintenance and replace on completion. If we believe an external competent authority is required then any advise?
Thanks

Your Competent Rigger will only tell you how they intend to lift and shift the load. In terms of suitability of lifting points you would need to get in touch with your local Lifting equipment engineers who would advise on how best to load test the lugs. Depending on whereabouts in Yorkshire you are you could try Northern Lifting (I have no affiliation to them) They do our load testing and are very reasonable.
Hope this helps,
Steve

Appreciate the role of the rigger, who will only give us 'how' he would lift it. Have looked a little deeper and it looks like we have specifications and types of welds to use and what NDT we need to undertaken, however these are in 'german'.
Happy days.

Waz, the lugs require to be an 'engineered item', these will also need to be attached by whichever means the engineer decides, if this is welded then you will need to have the welds suitably inspected & tested, can they be bolted on? Multiple lifting points are a must, this will also help the rigger should the load not be equally balanced / centred.
Best of Luck

Hi,
You will need to have new lugs designed to fit onto the load, the dimensions of which have been proved by calculation.
Before welding the lugs to the load, the area that the lugs will be attached to needs to be tested for laminations in the steel. UT could be a solution.
As you will probably be welding new steel to old, you will need to think about the welding procedure and ensure that your welders are coded.
After welding, the weld must be tested for defects. MPI could be a solution here.
You will probably want to decide the placement of the lugs in conjunction with your rigger to ensure a balanced lift.
Hope this helps (a bit) - Neil.
