Before initial usage of the RUD VWBG
hoist rings please read carefully the safety
instructions. Make sure that you have un-
derstood all subjected matters.
Non-observance can lead to serious per-
sonal injuries and material damage and
eliminates warranty
1 Safety instructions
ATTENTION
Wrong assembled or damaged lifting points as
well as improper use can lead to injuries of per-
sons and damage of objects when load drops.
Please inspect all lifting points before each use.
• Remove all body parts (ngers, hands, arms, etc.) out
of the hazard area (danger of crushing or squeezing)
during the lifting process.
• RUD VWBG lifting points must only be used by instruc-
ted and competent persons considering DGUV 100-500
(BGR 500) and outside Germany noticing the country
specic statutory regulations.
• Do not exceed the working load limit (WLL) indicated
on the lifting point (except when used at straight lift and
with an optimized suspension link position - see Pic. 1
and table 3).
• A permanent turning action under load is not permissable.
RUD hoist rings VWBG are rotable 90° to the bolt-on
direction with the nominal working load limit.
• The load ring must not be bend.
• Ball bearing must not be disassembled.
• No technical alterations must be implemented on the
VWBG.
• No people may stay in the danger zone.
• Jerky lifting (strong impacts) should be prevented.
• Always ensure a stable position of the load when lifting.
Swinging must be prevented.
• Damaged or worn VWBG must never be utilised.
2 Intended use of VWBG
RUD VWBG lifting points must only be used for the assem-
bly at the load or at lifting means.
They are intended to be hinged into lifting means. RUD
hoist rings VWBG are rotable 90° to the bolt-on direction
with the nominal working load limit. A permanent turning
action under load is not permissable.
RUD VWBG lifting points can also be used as lashing points
to attach lashing means.
RUD VWGB lifting points must only be used in the hereby
described operation purpose.
3 Assembly- and instruction manual
3.1 General information
• Capability of temperature usage:
Usage at higher temperatures is not recommended due
to the grease lling in the ball bearing.
Should this though be necessary, the working load limit
(WLL) of the VWBG must be reduced as follows:
- -40°C up to 200°C no reduction
- 200°C up to 300°C minus 10 %
- 300°C up to 400°C minus 25 %
- Temperatures exceeding 400°C are prohibited!
Please pay attention when using DIN EN 7042 (DIN
980) nuts the max. operation temperature of 150°C
(acc. to DIN EN ISO 2320).
• RUD VWBG lifting points must not be used with aggres-
sive chemicals such as acids, alkaline solutions and their
vapours.
• Please mark mounting position of lifting point with a
coloured contrast paint for better visibility.
3.2 Hints for the assembly
Basically essential:
• 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 authority BG, recommends the following minimum
for the bolt lengths:
- 1 x M (thread diameter) in steel
(min. quality 235JR [1.0037])
- 1.25 x M (thread diameter) in cast iron
(e.g. GG 25)
- 2 x M (thread diameter) in aluminium
- 2.5 x M (thread diameter) in light alloys of low
strength (M = thread size/diameter, e.g. M20)
• 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 base material.
• The position of the lifting points must be carried out in
such a way that unintended movement like turning or
ipping will be avoided.
• For single leg lifts, the lifting point should be verti-
cally above the centre of gravity of the load.
• For two leg lifts, the lifting points must be equidi-
stant to or above the centre of gravity of the load.
• For three and four leg lifts, the lifting points
should be arranged symmetrical around the cen-
tre of gravity, in the same plane if possible.
• Load symmetry:
Determine the necessary WLL of each lifting point for
a symmetrical or an unsymmetrical load by using the
following physical calculation formula:
WLL = necessary WLL of lifting point / single strand
G = weight of load
n = number of load bearing strands
ß = inclination angle of single strand
G
n x cos ß
WLL=
Number of load bearing strands:
Symmetric Unsymmetric
two leg 2 1
three / four leg 3 1
Table 1: Load bearing strands
• A plane bolt-on surface (ØD) with a perpendicular th-
read hole must be guaranteed. The countersink of the
thread hole must be = nominal thread diameter plus
4 mm (RUD Lifting Points VLBG, VRS and PP each larger
than M30, can be installed into these tapped holes)
• Tapped holes must be machined deep enough so that
the bearing surface of the lifting point will be supported.
Machine through holes up to DIN EN 20273-middle.
• Due to the ball bearing it is sucient for a single lift to
tighten the VWBG until the bearing surface has support
by using a spanner acc. to DIN 895 resp. DIN 894, wit-
hout using an extension. If the VWBG shall permanently
installed at the load, tensioning must be carried out with
a torque (+/- 10 %) according to table 2.
• The type VWBG can be supplied with dierent thread
lengths (see Fvario in chart 2), and the metric versions
with washer und crack detected nut.

VWBG 3
ATTENTION
Disassembly of the ball bearing resp. the bush
bearing disc carried out by the user is forbidden.
• Check nally the correct assembly (see chapter 4, In-
spection / repair).
• The VWBG must not be loaded with the Manufacturing
Proof Force MPF (2.5 x WLL). Should at the production of
lifting means or similar products, a singular proof loading
be necessary, please ask RUD in advance.
3.3 User instructions
• Check frequently and before each initial operation the
whole lifting mean in regard of linger ability as a lifting
mean, regarding corrosion, wear, deformation etc. (see
chapter 4, Inspection / repair).
ATTENTION
Wrong assembled or damaged lifting means
as well as improper use can lead to injuries of
persons and damage of objects when load falls.
Please inspect all lifting points before each use.
• RUD components are designed according to DIN EN 818
and DIN EN 1677 for a dynamic load of 20,000 load cycles.
• Keep in mind that several load cycles can occur
with a lifting procedure
• Keep in mind that, due to the high dynamic stress
with high numbers of load cycles, that there is a
danger that the product will be damaged
• The BG/DGUV recommends: For higher dynamic
loading with a high number of load cycles (con-
tinuous operation), the working load stress must
be reduced according to the driving mechanism
group 1Bm (M3 in accordance with DIN EN 818-7).
Use a lifting point with a higher working load limit.
• VWBGs are suitable for turning and ipping of loads. In
doing so, all positions of the ring can occur. The stated
WLL at the lifting point is given for the most inappropriate
possible case of operation (see picture 1 – part X). When
ring has been adjusted manually (see picture 1 - part Y)
the higher (WLL) values from table 3 can be used.
ATTENTION
Pay attention during the usage that the
load type will not be change.
If the VWBG is will be loaded only perpendicular (in axial di-
rection of the thread, see picture 1 - part Z) the corresponding
WLL values from table 3 (inclination angle 0°) can be used.
• The ring of the manualy adjusted VWBG can be pivoted
by approx. 230° (see picture 2).
ATTENTION
The suspension ring resp. the attached lifting
mean must rotate and pivot without interference
during lifting and must neither have support
at the load edge nor at the bottom part of the
VWBG (see picture 3).
• When lifting means (sling chains) are hinged or unhinged,
no pinching, shearing or joint spots must occure during
the handling. Avoid damage of lifting means resulting
from sharp edges.
• Leave direct danger zone as far as possible.
• Watch always your hinged loads.
• VWBG must have been fully bolted in.
• Thread of the VWBG must be completely engaged and
the lifting point must be installed full-faced. (The diameter
of the bearing surface must be ≥ D, see table 2).
• Avoid impulsive and tiltful loading.
ATTENTION
Impulsive loading or vibration, especially at
through hole connections with nuts, can lead to
unintentional loosening.
Securing possibilities: liquid thread securing products f.e.
Loctite (read manufacturer´s instruction) or form closed
bolt securing such as a crown nut with split pin, lock nut
etc. can be used. Secure in general all lifting points which
are installed permanently, e.g. with glue.
• Please observe for the whole lifting mean the RUD sling
chain safety instruction.
4 Inspection / repair
4.1 Hints for periodical inspections
The operator must determine and specify the nature and scope
of the required tests as well as the periods of repeating tests
by means of a risk assessment (see sections 4.2 and 4.3).
The continuing suitability of the anchor point must be chek-
ked at least 1x year by an expert.
Depending on the usage conditions, f.e. frequent usage,
increased wear or corrosion, it might be necessary to check
in shorter periods than one year. The inspection has also to
be carried out after accidents and special incidents.
4.2 Test criteria for the regular visual inspection
by the user
• Correct bolt- and nut size plus thread engagement
• Solid bolt xture - Inspection of bolting torque
• The bearing surface of the VWBG must lay plane and
holohedral on the bolting area.
• Completeness of the lifting point
• Complete, readable WLL statements as well as manu-
facturer sign.
• Deformation at load bearing components like base body,
suspension ring and threaded pin.
• Mechanical damage, like strong notches, especially in
areas where tensile stress occurs.
• Locking screw at the side must be tightened
• Easy turning without jerk between upper and base part
of the VWBG must be guaranteed.
• The maximum allowance for clearance of s = 4 mm, between
upper and base part must not be exceeded, respectively the
proof groove in the ring connection must not be visible.

4.3 Additional test criteria for the
competent person / repair worker
• Reduction of cross-section due to wear >10 % or when
the wear lenses have been reached in the main load
bearing directions
• Strong corrosion
• Any other damage
• Function and damage of bolt threads and nuts
• further checks may be required, depending on the result
of the risk assessment (e.g. testing for cracks in load-
bearing parts).
