POWERTEX Web Lashing
Instruction for use (GB) (Original instructions)
WARNING
• Failure to follow the regulations of this instruction for use may cause
serious consequences as risk of injury.
• Read and understand these instructions before use.
Information for use and maintenance
Check the current regulations as required to achieve the approved car-
go securing. For transport within Europe the securing of cargo in most
cases meet the requirements of EN 12195-1.
GENERAL
Selection of lashing
When selecting and using lashing shall take into account demand
lashing capacity, method of use and the type of cargo to be lashed.
The size, shape and weight of the load, the intended method of use,
transport environment and the nature of the load affects the choice of
twine. When friction lashing of independent cargo, for reasons of stabi-
lity, at least 2 lashings should be used and in diagonal lashing at least
4 lashings should be used.
OPERATION
Generally
a) Make sure the webbing is not damaged by the sharp edges of the
load as it buzzes.
A visual inspection before and after each use is recommended.
Only lashings with readable label (label / tag) will be used.
b) Lashings must not be overloaded - only manual force may be used
up to 500 N (50 daN = 50 kg).
Mechanical means such as levers or pipes etc. may not be used un-
less it is part of the tensioning device.
c) Lashings should never be used if they are linked.
d) Damage to labels and marking plates shall be prevented by keeping
them away from the corners of the load or, if possible, from the load.
The webbing, cargo or both must be protected against wear
and damage using wear protection/inserts and/or corner
protectors.
LC (Lashing Capacity) must not be exceeded,
instructions on the label MUST be followed!
Preparations
The selected lashing must be both strong enough and of the right
length for the purpose.
Basic lashing rules:
a) Plan the fitting and removal operations of lashing before starting a
transport.
b) keep in mind that parts of the load may be unloaded during long
transports.
c) calculate the number of lashings acc. to EN 12195-1.
d) only the lashings designed for frictional lashing with STF the label
should be used for friction lashing.
e) verify lashing force periodically, especially shortly after the shipment
started.
f) should the carrier, e.g. trailer, at any stage of the transport chain to
go with other modes of transport, for example via rail or sea, then other
calculation methods for safe securing of loads than only to EN 12195-1
need to be taken into account.
Because of the different characteristics and elongation under tensi-
on, different lashing equipment (e.g. lashing chain and web lashings)
should not be combined to lash the same cargo.
When replacing the short or long part of the lashing, the
initial value of the lashing's STF is no longer guaranteed,
regardless of the stated value of the labels.
When using flat hooks, they should be loaded over their entire width.

Loading and unloading
Ensure that the stability of the load is not dependent on the lashing
strap and that can be released without load to fall of the vehicle, and
exposes the personnel at risk. Ensure that the stability of the load is
not dependent on the lashing strap and that it can be released without
load falling of the vehicle, and exposes the personnel to risk. This also
applies lashing equipment with controlled relief.
Before starting unloading of cargo, the lashings must be removed.
Lashing equipment must not be used for lifting or pulling.
Temperature effect
Web lashings are suitable for use and storage in the following tempe-
rature ranges:
- polyester: -40°C to 120°C,
These ranges change in a chemical environment in these cases should
the supplier be consulted.
Temperature fluctuations during transport may affect the lashing force.
Check lashing when the transport passes into a warmer area.
Acidic/alkaline conditions and chemical influence of synthetic
fibers
The materials used for lashings have selective resistance to chemicals.
Consult the supplier of the lashing to be exposed to chemicals. Note
that the chemical effect may increase with rising temperature.
The resistance of synthetic fibers to chemicals is summarized below:
- polyester (PES) is not affected by mineral acids (most) but damaged
by alkalis;
Harmless acid solutions or alkalis can evaporative become so concen-
trated that they can cause damage. Contaminated lashings should be
taken out of service immediately, rinse with cold water, air dried and
transferred to a competent person for examination.
Lashing components in grade 8/10 should not be used in acidic conditi-
ons. Contact with acids or acidic steam cause hydrogen embrittlement
in material of class 8/10. If exposure to chemicals is anticipated the
supplier should be consulted.
3. INSPECTION AND MAINTENANCE
Lashings should be discarded or returned to the supplier for repair if
they show any signs of damage.
The following are considered to be signs of damage:
Webbing:
a) only lashings that are marked should be repaired.
b) if lashing accidentally come in contact with chemical, products
should be taken out of service and the supplier be contacted.
c) lashing should be discarded at the following damage: tears and cuts
and fracture of the supporting fiber and/or stitches.
d) abnormalities because lashing exposure to heat.
Metal parts:
a) deformation;
b) cracks;
c) clear abrasion;
d) signs of corrosion.
