OPERATING INSTRUCTIONS
LIFTING POINTS "XKE-POINTS"
TWN 1884
6. ASSEMBLY AND REMOVAL
6.1 Preparations
All components to be installed or used must be in perfect
condition and the relevant working load limits of all parts must
accommodate the respective load to be handled.
The mounting location for each lifting point has to ensure that
• the load can take the forces including safety factors safely to
be applied without suffering deformation,
• the lifting point can be assembled flush,
• no areas of danger are created (crushing point, shearing
point),
• lifting and moving is not restrained by overhang,
• used lifting means (e.g. hooks) are freely movable and will
not be bended,
• incorrect use is avoided,
• the sling cannot be damaged, for example by sharp edges,
• lifting point can be used easily.
6.2 Assembly
The useful depth of the thread must enable the lifting points to
be safely screwed in. Use only the delivered screws!
The threaded hole must be perpendicular to the screw-on
surface in the load. The depth of the thread "L" of the
component must be at least as follows:
L = 1.0 x d for steel (yield stress R
L = 1.25 x d for castings
L = 2.0 x d for aluminum
L = 2.5 x d in aluminum-magnesium-alloys
(L = depth of thread; d = thread diameter)
• Make sure the threads of the lifting point and in the
component are clean and dry.
• For lifting points have to remain on the component a usual
fluid safety agent for screws has to be used.
• For through-boltings, the nut must be secured against
loosening.
• Single lifting operation WITHOUT turning or rotating:
Hand-tighten the screws with a suitable spanner for screws
with hexagon socket according to DIN.
It must be ensured that the screws of the lifting points
cannot loosen by themselves.
• Lifting WITH turning or rotating as well as multiple lifting
operations:
Tighten the screws to the tightening torques specified in the
technical data.
However, repeated lowering of the load to the ground
requires a new check!
Lifting points that remain on the loads should be tightened
to the tightening torques specified in the technical data.
• Chamfers on the threaded holes are not required.

6.3 Removal
Unload the lifting point and remove any lifting attachments
connected to it. Turn the screw counterclockwise and remove
the lifting point. Assure that no damage occurs during transport
and storage.

7. CONDITIONS OF USE

Continuous or long-term turning or rotating is not
An alternating use for lifting and lashing is not allowed.
7.1 Normal use
The working load limit for different applications of assembly can
be seen in the load table, chapter 5.2.
The force must be applied in the longitudinal direction of the
attached component (e.g. hook).
The attached component (e.g. hook) must always be able to
move freely. Supporting the component at the lifting point is not
permissible.
Using 4-leg chain sling assemblies may cause higher risk because
only two opposite legs may carry the load. Check the working
load limit of lifting points and chain sling assembly carefully and
chose if necessary bigger sizes.

foreseeable misuse:
