Respect the user instructions for the corresponding lifting points!
Before every use, please read the User
Instruction of the Lifting Points carefully and
make sure that you understand all substance.
Improper use or care of this eyebolt can result
in bodily injury or property damage and
eliminates any warranty!

Application and warning information
Reference should be made to country specific statutory
regulations and installation to be carried out by competent
skilled persons only.

General information
• 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.
• The material construction to which the lifting point will
be attached should be of adequate strength to withstand
forces during lifting without deformations.
• The lifting points must be positioned on the load in such
a way that non- permitted loads such as twisting or
turnings will be avoided.
-
For single leg lift, the lifting point should be
vertically above the center of gravity of the load.
-
For two leg lifts, the lifting points must be
equidistant to/or above the center of gravity of the
load.
-
For three and four leg lifts, the lifting points should
be arranged symmetrically around the center of
gravity in the same plane.
• Load symmetry
The required WLL of the individual lifting point has to be
calculated based on the following formula
WLL = Working load limit (kg)
G
G =
W
=
n =
LL
n x cos ß

The number of bearing legs is:

• Capability of temperature usage:
Please observe corresponding user instruction of each
part resp. see website www.rud.com
• The places where the lifting points are fixed should be
marked with colour.

•
When handling the lifting means (sling chain), no
squeezing, shearing, catching and impact spots must
occur.
• Damaging of the lifting means and lifting points by sharp
corners has to be avoided.
• For the assembly of the lifting points, please follow the
user instructions enclosed.
• 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 (see
chapter 5 Inspection criteria).

Lifting Points for weld on
• The welding should be carried out by an authorised
welder acc. to EN 287-1.
• Effects of temperature
The lifting points for weld on, types VLBS, LBS, VRBS,
RBS, VRBK and RBK can together with the load (e.g.
weld construction) be one-time low-stress annealed
without reduction of WLL. Temperature < 600° C.
• Material of the welding block is S355J2+N (1.0577+N,
St 52-3N, B.S. 4360.50D, AISI 1019)
• The connecting surfaces must be free from dirt, oil,
colour, etc.
• Do not weld at the red or pink powder coated tempered
load ring.
• The complete construction can be annealed stress free
at <600°C without reduction of WLL.
• The welding spot has to be suitable for the corresponding
force.
• The distance lugs assist in achieving the required root
weld (approx. 3 mm).
ATTENTION:
By the arrangement of weld (continuous HV),
the following requirements are fulfilled:
DIN 18800 for steel building prescribes:
At outdoor sites or in case of spezial danger of
corrosion,the weld should only be designed as
continuous, fillet welds. The HV weld at the
VLBS, WPP, WPPH, VABH-W, VRBK assures
a connection via the whole cross section of the
material. This corresponds to a closed weld
showing no signs of corrosion.
