LIFTING POINTS
SCREW TYPE

7.2 Normal use

The working load limit for different applications of assembly can
be seen in the load tables, Table 3 and Table 4.
The top part of the lifting point including attachment link must
always be freely movable.
It must not rest on or be supported by other structural parts.
When attaching the components, make sure the position of the
lifting point always enables forces to be exerted in longitudinal
direction of the suspension link.
Make sure only the top parts of the lifting points turn into
loading direction and not the firmly secured stationary portions.
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.
TWN 1830:
The lifting point must not be used for a permanent or
prolonged turning of the load.
Take care for the usage of the preferred alignment
shown below:
PREFERRED REDUCED
If used, a load
reduction
acc. to
Table 4 must
be observed.
Please note that the values for the working load limits as a
function of number of legs and sling
on the preferred alignment.
The use of nominal sizes from M52 up to manufacturing date
"0423" (April 2023) is only permitted above 0° C, from
manufacturing date "0523" (May 2023) this restriction does
#
not apply.
Take care for a loss of lubricant depending on several fitting
positions and higher temperatures. A higher wear may occur.
Shorten the inspection interval for that case.

TWN 1890:
7.3 Use in through holes
If screwable lifting points are fastened by means of nuts in
holes (e.g. of metal sheets), the following conditions must be
observed:
• Rotating or turning the load is not permitted.
• The strength class of the nuts must be 10 or higher.
• The chamfer at the end of the screw thread must protrude
from the nut.
• It must be ensured that the component to be lifted is suitable
to withstand the force to be applied safely and without
deformation, including the corresponding safety factors.
• Suitable action must be taken to ensure that the nut cannot
loosen unintentionally, e.g. suitable torque or threadlocker.

7.4 Influence of temperature

The permissible working load limit of the lifting points reduces
at elevated temperatures.
The reduced working load limit figures shown in the following
tables shall only apply for short-term use at the temperatures
indicated.
Temperature range
-20° C ≤ t ≤ 100° C
- 4° F ≤ t ≤ 212° F
100° C < t ≤ 205° C
212° F ≤ t ≤ 400° F
205° C < t ≤ 250° C
400° F ≤ t ≤ 482° F
250° C < t ≤ 300° C
482° F ≤ t ≤ 572° F
