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 sym-
metrically around the centre of gravity in the same plane.
5. Load Symmetry:
The working load limit of individual RUD lifting points are calculated
using the following formula and are based on symmetrical loading:
W
= working load limit
G
LL
G
= load weight (kg)
W
=
n x cos ß
LL
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:
symmetrical
two leg
2
three / four leg
3
(see table 1 and 3)
When using the eyebolt perpendicular only, the WLL from table 1 can
be used.
6. Drill and tap the work piece so that the eyebolt is installed perpendicu-
lar to the surface of the work piece. The work piece surface must be flat,
providing complete contact for the eyebolt.
7. Rotation during the transportation must be avoided.
8. All fittings connected to the eyebolt 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.
9. To prevent unintended dismounting through shock loading, rotation or
vibration, thread locking fluid such as Loctite (depending on the application,
please pay attention to the manufacturer's instruction) could be used to
secure the bolt, or use form-closed devices. For lifting points which remains
on the construction we basically recommend to secure with liquid locking
device or tighten with torque.

10. Effects of temperature:
If the RUD-Eyebolts are to be used in temperatures ranging from 200°C
upwards, the WLL has to be reduced accordingly:
-40° up to 200°C
no reduction
200° up to 300°C
minus 10 %
300° up to 400°C
minus 25 %
Temperatures above 400°C (752°F) are not permitted.
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. The places where the lifting points are fixed should be marked with
colour.
13. After fitting, an annual inspection or sooner if conditions dictate should
be under taken by a competent person examining the continued suitability.
Also after damage and special occurrences.
Inspection criteria concerning paragraphs 2 and 13:
•
Ensure compatibility of bolt thread and tapped hole
•
The plane area of the eye bolt can completely flat down
to the work piece.
•
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 and 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.
A non-adherence to this advice may result damages of per-
sons and materials!
