VRBS-FIX
3.3 Hints for the welding
The welding should only be carried out according to
DIN EN ISO 9606-1 or AWS Standards by an autho-
rized and certified welder.
Verification of the used weld-on material must be
checked with the supplier of the welding electrodes.
HINTS
• Never weld at the quentched and
tempered ring!
• Weld all seams at the same temperature.
• The pre-heating temperature for the
welding of the VRBS-FIX 31.5 t, 50 t
and 100 t must be between 150°C and
170°C.
1. Check before initial appending of the VRBS-Fix, the
position of the weld-on blocks to each other, that
means the base area must be at the same level.
2. Append weld-on blocks.
3. Check function of the ring. The ring must be able
to pivot 180°. If necessary please correct.
4. Remove any welding mistakes and dirt at the root
weld before applying the cover weld seams.
5. Weld blocks on.
Choose type of weld seam and size according to
picture 3 and chart 4.
6. Please check by a competent person after welding
the ongoing usage of the weld-on lifting point (see
chapter 4,
Inspection criteria
)
HINT:
By the position of the weld-seam (HY-weld
circumferential) the following requirements
will be observed: DIN 18800 steel con-
structions requires: at outdoor buildings or
when strong corrosion must be expected
weld seams must be carried out as conti-
nuous fillet weld seams.
3.4 User instructions
• Check frequently and before each initial operation
the whole lifting point in regard of linger ability as a
lifting mean, regarding corrosion, wear, deformati-
on etc. (see chapter 4,
Inspection criteria
).
ATTENTION
Wrong positioned or damaged weld-on
lifting points as well as improper use can
lead to injuries of persons and damage at
property, when load falls down.
Please check all lifting points carefully
before every usage.
• Please check carefully the wear indicator markings
of the weld-on lifting point (see picture 1):
Usage permitted:
no wear marks
visible
Use prohibited:
Replacement criteria rea-
ched. Material all the way
down to the wear lenses

Picture 1: Wear indicators
• Please note that the lifting mean must be free
moveable within the weld-on lifting point VRBS-
FIX. 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.
• If RUD-VRBS-FIX lifting points are used solely
for lashing, the value of the working load limit can
be doubled. LC = permissible lashing force = 2 x
working load limit (WLL)
3.5 Hints for regular inspection
In time periods complying to the need or usage, a
technical expert must control at least once a year the
appropriateness of the anchor point. This inspection
must also be done after each event of damage or
special incident.
4 Inspection criteria
Observe and control the following points before each
initial operation, in regular time intervals, after the
as-sembly and after special incidents.
• Completeness of the lifting point
• Complete, readable WLL statements as well as
manufacturer sign.
• Deformation at load bearing components like base
body and Ring.
• Mechanical damage, like strong notches, especial-
ly in areas where tensile stress occurs.
• Reduction of cross-section due to wear >10 %
• Evidence of corrosion (pitting)
• Evidence of cracks
• Cracks or other damages at weld seam
