4 INSTALLATION AND INTENDED USE
The straps' pre-selected fabric must be strong enough and the correct length for the manner
of use. The requirements for anchoring to a base are:
Determine the mass, shape and centre of gravity for the load to be anchored;
Determine the fixing points for the straps;
Check the tensile strain capacity (LC) of the straps before tightening;
Check that the load is stable in the absence of a tie down;
Plan the mounting and removal of the strap before moving;
Remember that while moving, it may be necessary to unload parts of the load;
Calculate the number of fabric straps in accordance with UNI EN 12195-1:2010;
Only the fabric straps designed for friction securing and with the label that carries the
abbreviation S
TF
must be used for friction anchoring;
Periodically check the tensile load, especially immediately after initially moving the
load.
Selecting and Using the Straps
While selecting and using the fabric straps, one must take into account the required payload
of the strap, taking into account the mode of use and the nature of the load to be fixed. The
size, shape and weight of the load, together with the method of intended use, transportation
environment and the nature of the load, affect the correct choice. For reasons of stability, the
load's self-supporting units must be secured with at least a pair of fabric straps for friction
anchoring and two pairs of fabric straps for diagonal anchoring.
The fabric straps should not be overloaded: The maximum manual load of 500 N should be
applied (50 daN on the label; 1 daN = 1 kg). Mechanical aids (such as levers, bars, etc.)
should not be used as extensions, except in the case where they form part of the tightening
device.
Selecting and Using the Straps
Due to the different behaviour and breadth of load conditions, different anchoring or tie down
equipment should not be used (for example, tie down chains and fabric straps) to anchor the
same load. Attention should also be given to the fact that the auxiliary hooks (components)
and tie down devices within the load's tie down device are compatible with the fabric strap.
Storing the Strap
Before using the strap, check that it has been properly stored away from UV light sources
(direct sun exposure) and without deep wrinkles, twists or knots that may have weakened the
fibre.
