RUD "VRBS" & "RBSB" Weld Down Swivel Load Ring Lifting and Lashing Eye - Range from 3000kg to 50000kg

Lifting Eye Plate for Welding, RUD VRBS.

Force distribution by 2-point-attachment, required thinner welding seams.

The lifting eye weldable VRBS / RBS is prepared for the direct welding at the transport goods. 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 180°, made of high-tensile material, 100% crack detected and thus overall loadable.

Load Ring Information

An enhancement of the well established RBS series with an up to 30% increment of the WLL!
The two points of attachment facilitate an even and optimal force distribution into the work piece and thus, usage of thinner base plates is possible.
A forged, pink coated ring bracket according to EN1677-1.
The welding block is forged out of a good welding material 1.0577+N (St 52-3).
Low profile, high dynamic and static strength.
The ring is stowable and okkothus avoiding the hazard of tripping.

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:

WLL =	G        n x cos ß	WLL = Working Load Limit G = Load Weight (kg) n = Number of load bearing legs ß = Angle of inclination of the chain to the vertical

The calculation of load bearing legs is as follows:

No. Legs	Symmectrical	Asymmetrical
Two Leg	2	1
Three / Four Leg	3	2

(See Table 1 and 5)

6. All fittings connected to the VRBS 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 distance lugs assist in achieving the correct root weld (approx. 3 mm = 0.1 inch). They may not be removed.

9. 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 be avoided, please contact the manufacturer indicating the concentration, period of penetration and temperature of use.

10. The places where the lifting points are fixed should be marked with colour. The load ring of the VRBS is pink powder coated.

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

12. After welding, an annual inspection, or sooner if conditions dicate, should be undertaken by a competent person examining the continued suitability. Also after damage and special occurrences.

Inspection criteria concerning paragraphs 2 and 12:

• 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.

A non-adherence to this advice may result damages of persons and materials !
