User Instructions1. Reference should be made to German Standardsaccording BGR 500 or other country specific statutoryregulations and inspections are to be carried out by competentpersons 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, etc.The material of the forged welding block is S355J2+N (St52-31.0577+N), B.S. 4360.50 D or AISI 10194. 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:W LL=Gn x cos ßW LLGnß= working load limit= load weight (kg)= number of load bearing legs= angle of inclination of the chain to the verticalThe calculation of load bearing legs is as follows:symmetrical asymmetricaltwo leg 2 1three / four leg 3 2(see table 1+ 5)6. All fittings connected to the RBS should be free moving.When connecting and disconnecting the lifting means (slingchain) pinches and impacts should be avoided. Damage of thelifting means caused by sharp edges should be avoided aswell.7. The complete design can be annealed stress-free up to

The welding shouldonly be carried outaccording to EN 287 orAWS Standards by anauthorized welder.Welding sequence:1 Welding of the block.The distance lugs assistin achieving the correctair gap for the root ofseam weld (approx.3mm, or 1/8") Lugs mustS *not be removed! Startwelding of root seam andtop run at point „S“ (seedrawing). Before carrying out roof weld (top run), carefullyclean root of seam. Append fillet weld (measurement „a“)acc. Chart 3. The whole welding should be carried out at thesame temperature. Do not interrupt welding. Keep area ofwater outlet open.2 Insert ring in the welding block. Attach second weldingblock as tight as possible to the ring, in order to stillguarantee moveability of same. Only fasten provisionally.3 Examine on 180° tilting ability. Possibly make corrections.4 Weld on second welding block, as described under 1 .• Attention: Do not weld at the red powder coated,heat treated load ring.Method of liftNumber of legs 1 1 2 2 2 2 2 3 and 4 3 and 4 3 and 4Angle of inclination
