This page has now expired please view the new RUD "VRBK-FIX" Weld on Corner Swivel Load Ring Lifting & Lashing Eye.

The welding point for all 90° edges.

The lifting eye, ready for welding VRBK / RBK is prepared for the direct welding at 90° corners at the transport goods. Directly attached at the corner, it saves the double number of lifting eyes. The welding blocks (made of easy weldable material 1.0577+N St. 52-3) have been provided with distance nabs as gap indication for the weld and stamped with the WLL identification number. The ring latch can be tilted by 270°, made of high-tensile material, 100% crack detected and thus overall loadable.

Eye Plate for Corners

• An enhancement of the well-established RBK - series with an over 30% increment of the WLL.
• A forged ring bracket according to EN1677-1, electromagnetically crack detected, pink powder coated and it can be loaded in all directions.
• Even force distribution owing to the two point attachment.
• Low profile sice it can be folded with in an angle range of 270°.
• The welding block for edges is forged out of a good welding material 1.0577+N (St 52-3) and clearly stamped with an identification number for the permissible WLL.
• Welding should only be carried out by qualified persons according to EN 287-1.

Proof Testing

There is no requirement to Proof Test RUD Products, either Bolt or Weldable after Installation if the user instructions for welding are carried out correctly. The welding should be carried out by a suitably qualified and competent welder/person.

The supporting structure, or the load, should be of adequate strength to take the stresses involved and this is the responsibility of the engineering designer or equivalent.

RUD Lifting and Lashing Products are Manufactured and conform to EN 1677. No further Proof Testing in the field is required. In fact it would be considered that the Product had been overloaded if a Load more than the recommended Working Load Limit had been applied.

RUD products should be regularly inspected in line with the requirements of LOLER and as per our user instructions at intervals decided by a competent person.

User Instructions

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

2. Before installing and every use, visually inspect RUD lifting points, paying particular attention to any evidence of weld cracks, corrosion, wear, deformations, etc.

3. The material construction to which the lifting point will be attached should be of adequate strength to withstand forces during lifting without deformation. The contact areas must be free from inpurities, oil, colour, etc.
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 a way that movement is avoided during lifting.
a.) For single leg lifts, the lifting point should be vertically above the centre of gravity of the load.
b.) For two leg lifts, the lifting points must be equidistant to/or above the centre of gravity of the load.
c.) For three and four leg lifts, the lifting points should be arranged symmetrically around the centre of gravity in the same plane.

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

The calculation of load bearing legs is as follows:

(See Table 1)

6. All fittings connected to the VRBK should be free moving. When connecting and disconnecting the lifting means (sling chain), pinches and impacts should be avoided. Damage of the lifting means caused by sharp edges should be avoided as well.

7. The complete design can be annealed stress-free up to <600°C (1100°F) without reduction of WLL.

8. The places where the lifting points are fixed should be marked with colour.

9. At outdoor sites or in case of special danger of corrosion, the welds should only be designed as continuous, fillet welds.
The HV weld at the VRBK guarantees a connection via the whole cross section of the material. This corresponds to a closed weld showing no signs of corrosion.

10. The distance lugs assist in achieving the correct root weld (approx. 3 mm = 0.1 inch). They should not be removed.

11. RUD-Lifting points must not be used under chemical influences such as acids, alkaline solutions and vapours e.g. in pickling baths or hot dip galvanising plants. If this cannot avoided, please contact the manufacturer indicating the concentration, period of penetration and temperature of use.

12. If the lifting points are used exclusively for lashing the value of the working load limit can be doubled.
LC = 2 x WLL

13. After welding, an annual inspection or sooner if conditions dictate should be undertaken by a competent person paying particular attention to the following.

Inspection criteria concerning paragraphs 2 and 13:

• The lifting point should be complete.
• The working load limit and manufacturers stamp should be clearly visible.
• Deformation of the component parts such as body and load ring.
• Mechanical damage, such as notches, particulary in high stress areas.
• Wear should be no more than 10% of cross sectional diameter.
• Evidence of corrosion.
• Evidence of cracks.
• Cracks or other damage to the weld.

Any non-adherence to this advice may result damages of persons and/or materials!

Welding sequence:

The welding should only be carried out according to EN 287 or AWS Standards by an authorised welder.

1. Welding of welding block VRBK.
The distance lugs serve as distance measurement for required gap for the root welding. Start of root and fillet weld at point 'S' (see drawing). Before carrying out the fillet weld, carefully clean the root. Possibly filled weld. Fix size 'a' acc. the table 3. The complete weld should be carried out in one heat.

2. Insert ring in welding block. Attach second welding block as tight as possible to the ring, in order to still guarantee 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 pink powder coated, heat treated load ring.
