RUD-Load Rings VLSB Welding Instructions
10 June 2013

1. Reference should be made to German Standards accord.BGR 500 or other country specific statutory regulations andinspections are to be carried out by competent persons only.

2. Before installing and every use, visually inspect RUD liftingpoints, paying particular attention to any evidence of weldcracks, corrosion, wear, deformations, etc.

3. The material construction to which the lifting point will beattached should be of adequate strength to withstand forcesduring lifting without deformation. The contact areas must befree from inpurities, oil, colour, ect.The material of the forged welding block is S355J2+N (St52-3,1.0577+N), B.S. 4360.50 D or AISI 1019

4. The lifting points must be positioned on the load in such away that movement is avoided during lifting.

a.) For single leg lifts, the lifting point should be verticallyabove the centre of gravity of the load.
b.) For two leg lifts, the lifting points must be equidistant to/orabove the centre of gravity of the load.
c.) For three and four leg lifts, the lifting points should bearranged symmetrically around the centre of gravity in thesame plane.

5. Load Symmetry:The working load limits of individual RUD lifting points arecalculated using the following formula and are based onsymmetrical loading:
