• These are available in widths from 25 mm to
450 mm.
• The colours of the lifting straps correspond to the
working load limits according to EN 1492-1:
– 1 t – violet
– 2 t – green
– 3 t – yellow
– 4 t – grey
– 5 t - red
– 6 t – brown
– 8 t – blue
– ≥ 10 t – orange
Note:
The harness strap material used for the
lifting straps is dyed. Direct contact can
lead to staining or colour imprints on
surfaces (e. g. plastics, painted surfaces,
etc.). This can be avoided by using suitable
intermediate layers.
• The lifting strap is inseparably sewn together via
a defined seam pattern. This seam pattern varies
in length depending on the type of lifting strap and
working load limit.

General remarks
Table 1 shows the working load limits of the
different rigging methods. The suitability of
the rigging method must be checked in
every case.
The safe working load (SWL) of a single
lifting strap corresponds to the working load
limit with the „direct" rigging method with
an angle of inclination ß of 0°.
