Common attachment methods for
using webslings in pairs
a) direct
23
b) choked
If more than one lifting sling is
used for the lifting process, they
must all be identical.
Uneven elongation of the
webslings poses a danger of
tilting the load.
With symmetrical load
distribution, equal sling lengths
and equal angles according to LOLER for
a 4-leg sling, only three legs are
considered to bear load.
With asymmetrical load
distribution and/or unequal
angles, with 2-leg slings, only one leg
can be considered load-bearing, and with
3 or 4-leg slings, only two legs can be
considered load-bearing.
If lifting slings are used in pairs, use
of a spread beam is recommended,
so that the load is distributed evenly

3.3 VarioWeb websling
shortener
VarioWeb offers continuous length
adjustment of websling. For this,
VarioWeb is easily integrated into the
websling individual straps. Then the
length of the sling can be adjusted to the
load and its special geometry.
24 1. Flip the buckle rightward to release
the
webbing
2.
Adjust the websling by sliding
lengthwise
3. Flip the buckle to the left
4. Thread the websling into the guide
slot, and you’re done!
3.4 Choosing the nominal load
capacity
The lifting straps’ nominal load
capacity must be greater than or
equal to the load’s mass. When
choosing the webslings, pay
attention to which attachment
method method and the angle at
which the lifting process is to take
place, because this affects the
useful load capacity of the lifting
sling. The lifting sling must lie
completely on the load suspension
device (e.g. crane hook) and on
the load.
Attention: Too tight a
bearing point (pinching) decreases
lifting slings
load capacity.
3.5 Arranging the load
Place the lifting sling on the load in
such a way that it cannot slip along
or even off the load during the
lifting process. Make sure the lifting
sling does not twist or intersect
with the load. Use adequate edge
protection for coarse and/or sharp-
edged loads
1
. Make sure that the
attachement point of the load to the
lifting sling can take the force
introduced during lifting.
4 Inspection, maintenance,
repair and disposal
Webslings/multi-leg slings must be
checked for defects before
each use. If you detect defects, the
webslings/multi-leg slings must be
withdrawn from use. An authorized
person must perform the check
according to the employer’s specifi ed
inspection interval, but at least in the
UK, twice per year. Depending on the
usage and operational conditions,
interim inspections may also be
necessary. The inspections must be
documented according to LOLER.
Additionally, all metallic fi ttings must
undergo crack inspection at least once
every three years. The inspection must
be done according to EN 10228 Part 1
(Magnetic powder testing - “fl uxes”) or
Part 2 (Penetration Test).
