Quality
controls and products testing are fundamentally important to us.
In a modern lab, our technical staff systematically analyses the
main properties of all the raw materials that we use and of the
products made from them.
Particular equipment helps us to collect a huge amount of data
about the mechanical resistance of each rope and about its
durability and reliability in time. Thanks to a computer
assisted testing machine, we are able to determine its breaking
load, its stress vs. strain tensile curve, its creep and
relaxation curves, as well as its mechanical behaviour under a
cyclic load process.
In order to
verify and eventually improve the abrasion resistance and the
structural performance of our ropes, detailed studies are also
carried out. Specific equipment allows us to simulate with
extreme realism the life cycle of a rope.
Testing several
different materials and rope constructions in identical
experimental conditions, we can be certain to offer every time
the best product for a specific application.
The breaking load
values that we report in our data sheets are measured on tensile
testers equipped with special clamps, which are able to simulate
real working conditions such as winding on small diameters,
friction on metal parts during traction, tangling. Although
standard laboratory tests would certainly allow us to claim
higher breaking loads, we believe that the results of these
tests in realistic conditions are more representative of the
actual resistance of the rope and definitely more interesting
for the end users.
It must be
stressed anyway that the working load of a rope should never
exceed 20% of the minimum breaking load reported in our data
sheets, which have been measured on unused ropes.
It is also
important to remark that the breaking load could be reduced by
more than 50% by the presence of knots.
