Rescue of Casualties
1. Functional description and
application
Webslings/Multi-leg slings are intended
for slingers (authorized persons) to use for
lifting loads. Webslings/Multi-leg slings
must be used as intended. The various
SpanSet webslings/Multi-leg slings can
be clearly identifi ed by their sewn in label
27
and accompanying documents. All
modifi cations to webslings are forbidden.
SpanSet webslings/Multi-leg slings are
made of reinforced synthetic fi bres (e.g.
polyester or polyamide).
Their production is EN ISO 9001 certifi ed.
2. Safety instructions and handling
Only trained (authorized) persons
may undertake lifting operations.
When choosing and using slings,
the weight and mode of use 19

must be considered. The
weight, geometry, surface condition and
design features of the load are crucial
criteria for selecting the sling.
A sling’s nominal load capacity
can change depending on the
connection method. The change in load
capacity is shown by the mode factor (M).
A sling’s nominal load capacity is
indicated in the “straight pull” mode. The
mode factor (M) for the rest of the
connection methods

can be found in this operating manual.
Using webslings/multi-leg slings
with chemicals is permitted
only with manufacturer approval.
The required data includes: chemical,
concentration, temperature and retention
time.
Before storage and reuse, the
user must clean webslings/
multi-leg slings that have come into
contact with acids, alkalis or other
aggressive substances. Ask your
SpanSet dealer or SpanSet about
cleaning processes.
When the temperature falls
below freezing, ice crystals form
in damp webslings/Multi-leg
slings and damage the webbing. This can
cause loss of strength, so damp
webslings must be dried in ventilated
areas before reuse.
Webslings made of polyester
(PES) have a blue label, and
webslings of polyamide (PA) have a
green label. It is safe to use polyester
and polyamide webslings within a
temperature range of -40°C to +100°C.
Webslings made of polypropylene (PP)
have a brown label and can be safely
used within a range from -40°C to +80°C.
Never use webslings/multi-leg
slings with illegible or missing
labels, because missing safety
instructions can lead to improper use.
Always lift and lower in
a smooth manner. Sudden
movement creates forces that
cannot be controlled. The
webslings/multi-leg slings may tear or
become damaged.
If there are people in the danger zone,
they must be warned that a
lifting process is being
performed and, if necessary,
they must be removed from the area of
immediate danger. It is prohibited for
anyone to be under a suspended load!
Hands and body parts must be kept away
from the slings in order to
prevent injury if the slings
tighten.
Plan the load’s connection, lifting and
lowering process with the greatest
of care before the actual lifting
process. Reckless connection can
damage the load or endanger employees’
life and health!
When lifting sharp-edged loads, protect
webslings/multi-leg slings with
protection sleeves (e.g. secutex
protection sleeves or NoCut
®
).
For net weight of 25 kg and above,
ergonomic handling of webslings/
multi-leg slings requires ancillary
equipment, such as pulleys.
Note that UV radiation (sunlight)
may impair the properties of the
sling.
Use webslings/multi-leg slings so
that the they may be removed
without damage after the lifting process.
3. Operating webslings/multi-
leg slings
3.1 First use
Before fi
rst use, the user must
inspect the webslings/multi-leg slings
for compliance with the order,
completeness of accompanying
documents (e.g. declaration of
conformity and manufacturer
certifi cate) and conformance of the data
in the accompanying documents with
the product labels. Upon fi rst use, an
authorized person must make a visual
check and document it according to
LOLER. For this, a chart can be created
or an inspection card fi lled out and
saved. Equipping products with RFID
tags and electronic documentation of
commissioning, such as with IDXpert
®
(database), speeds up and simplifi es this
process.
3.2 Selecting the right
webslings/multi-leg slings
Determine the load’s weight by weighing
or calculation! Find out the position of
the load’s centre of gravity from design
documents or calculate it! The crane
hook must be positioned perpendicularly
to the load’s centre of gravity, and the
length and angle of the webslings must
be determined.

webslings:
a) direct straight
b) choked
