User Instructions

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

2. Before installation and every use, inspect visually RUD lifting points, paying particular attention to any evidence of corrosion, wear, weld cracks and deformations. Please ensure compatibility of bolt thread and tapped hole.

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 German testing authoritiy BG, recommends the following minimum for the bolt lengths:
1 x M in steel (min. quality S235JR [1.0037])
1.25 x M in cast iron (e.g. GG25)
2 x M in aluminium
2.5 x M in aluminium-magnesium alloys
(M = thread Ø, e.g. M 20)
When lifting light metals, nonferrous metals and gray cast iron the thread has to be chosen in such a way that the WLL of the thread corresponds to the requirements of the corresponding base material.

4. The lifting points must be positioned to the load in such a way that movements are 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 symmetrical around the centre of gravity, in the same plane if possible.

5. Load symmetry:
The required WLL of the individual RUD lifting point 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 2 for metric and 3 and 4 for imperial on the Load Charts and Technical Specifications tabs above.)

6. Drill and tap the workpiece so that the WBG is installed perpendicular to the surface of the work piece. The workpiece surface must be flat, providing complete contact for the WBG ball bearing house.
Countersink the tapped hole (Nom. dia of thread + 4 mm).

7. Due to the ball bearing it is sufficient to tighten by hand with a spanner, without using a bar. For a long term application the WBG-V / WBG should be tightened with torque according table 2 or 4 (+/- 10%).

8. The WBG-V/WBG is designed to rotate and turn the load, therefore the lifting point can engage any position. That's why the WLL is embosed for the worst case situation which which can happen (Picture X)
The ring can be manually adjusted to direction of pull (Picture Y). Then the values in the brackets can be used.
Load Ring Picture X, Y and Z

9. All fittings connected to the WBG-V / WBG should be free moving.
Also the lifting ring must be free moveable and should not be used over sharp corners.
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.

10. With shock loadings, twisting or vibrations, especially with through bore-hole and nuts, an unintentional dismounting may occur.
Possibilities of securing: liquid means such as Loctite (respect manufacturer´s recommendations) or form closed bolt securing such as crown nut, counter nut etc.

11. Effects of temperature:
Due to the greasing we recommand to use the WBG-V/WBG not in overheated areas. If this cannot be avoided please take the reduced WLL into consideration.

12. 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 galvanizing plants. If this cannot avoided, please contact the manufacturer indicating the concentration, period of penetration and temperature of use.

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

14. The WBG-V can be supplied with variable thread sizes (see F vario table 2) and metric variations with washers and crack-detected nuts.
The assembly or modification of the bolt should only be done by RUD or authorized persons.

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

Inspection criteria concerning paragraphs 2 and 15:

  • Ensure correct bolt and nut size, quality and length.
  • Ensure compatibility of bolt thread and tapped hole.
  • 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, load ring, bolt or threaded bolt.
  • Mechanical damage, such as notches, particularly in high stress areas.
  • Wear should be no more than 10% of cross sectional diameter.
  • Evidence of corrosion.
  • Evidence of cracks.
  • Damage to the bolt, nut and/or thread.
  • On the WBG-V/WBG the ring must always rotate smoothly.
  • The WBG-V/WBG should only be used within its WLL.
    See chart.
  • The max. gap between the upper and lower parts of the WBG-V/WBG should not be exceeded:
    WBG-V 0.3 up to 0.45: max. 1.2 mm
    WBG-V 0.6 up to 2.0: max. 1.5 mm
    WBG-V 3.5 up to 5.0: max. 3.0 mm
    WBG 6 up to 35: max. 4.0 mm
Attention: The WBG-V/WBG is not suitable for prolonged turning application !
A non-adherence to this advice may result damages of persons and/or materials!

User Instructions

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

2. Before installation and every use, inspect visually RUD lifting points, paying particular attention to any evidence of corrosion, wear, weld cracks and deformations. Please ensure compatibility of bolt thread and tapped hole.

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 German testing authoritiy BG, recommends the following minimum for the bolt lengths:
1 x M in steel (min. quality S235JR [1.0037])
1.25 x M in cast iron (e.g. GG25)
2 x M in aluminium
2.5 x M in aluminium-magnesium alloys
(M = thread Ø, e.g. M 20)
When lifting light metals, nonferrous metals and gray cast iron the thread has to be chosen in such a way that the WLL of the thread corresponds to the requirements of the corresponding base material.

4. The lifting points must be positioned to the load in such a way that movements are 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 symmetrical around the centre of gravity, in the same plane if possible.

5. Load symmetry:
The required WLL of the individual RUD lifting point 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 2 for metric and 3 and 4 for imperial on the Load Charts and Technical Specifications tabs above.)

6. Drill and tap the workpiece so that the WBG is installed perpendicular to the surface of the work piece. The workpiece surface must be flat, providing complete contact for the WBG ball bearing house.
Countersink the tapped hole (Nom. dia of thread + 4 mm).

7. Due to the ball bearing it is sufficient to tighten by hand with a spanner, without using a bar. For a long term application the WBG-V / WBG should be tightened with torque according table 2 or 4 (+/- 10%).

8. The WBG-V/WBG is designed to rotate and turn the load, therefore the lifting point can engage any position. That's why the WLL is embosed for the worst case situation which which can happen (Picture X)
The ring can be manually adjusted to direction of pull (Picture Y). Then the values in the brackets can be used.
Load Ring Picture X, Y and Z

9. All fittings connected to the WBG-V / WBG should be free moving.
Also the lifting ring must be free moveable and should not be used over sharp corners.
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.

10. With shock loadings, twisting or vibrations, especially with through bore-hole and nuts, an unintentional dismounting may occur.
Possibilities of securing: liquid means such as Loctite (respect manufacturer´s recommendations) or form closed bolt securing such as crown nut, counter nut etc.

11. Effects of temperature:
Due to the greasing we recommand to use the WBG-V/WBG not in overheated areas. If this cannot be avoided please take the reduced WLL into consideration.
-40° to 100°C no reduction -40°F to 212°F
100° to 200°C minus 15% 212°F to 392°F
200° to 250°C minus 20% 392°F to 482°F
250° to 350°C minus 25% 482°F to 662°F
Temperatures above 350°C (662°F) are not permitted.

12. 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 galvanizing plants. If this cannot avoided, please contact the manufacturer indicating the concentration, period of penetration and temperature of use.

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

14. The WBG-V can be supplied with variable thread sizes (see F vario table 2) and metric variations with washers and crack-detected nuts.
The assembly or modification of the bolt should only be done by RUD or authorized persons.

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

Inspection criteria concerning paragraphs 2 and 15:

  • Ensure correct bolt and nut size, quality and length.
  • Ensure compatibility of bolt thread and tapped hole.
  • 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, load ring, bolt or threaded bolt.
  • Mechanical damage, such as notches, particularly in high stress areas.
  • Wear should be no more than 10% of cross sectional diameter.
  • Evidence of corrosion.
  • Evidence of cracks.
  • Damage to the bolt, nut and/or thread.
  • On the WBG-V/WBG the ring must always rotate smoothly.
  • The WBG-V/WBG should only be used within its WLL.
    See chart.
  • The max. gap between the upper and lower parts of the WBG-V/WBG should not be exceeded:
    WBG-V 0.3 up to 0.45: max. 1.2 mm
    WBG-V 0.6 up to 2.0: max. 1.5 mm
    WBG-V 3.5 up to 5.0: max. 3.0 mm
    WBG 6 up to 35: max. 4.0 mm
Attention: The WBG-V/WBG is not suitable for prolonged turning application !
A non-adherence to this advice may result damages of persons and/or materials!
