The production of our ropes begins with the
production of the wires.
The upmost attention is paid to the production of the metal wires
as it goes without saying that a good cable is obtained primarily from a good
wire.
The operation of making
wires is a delicate one it is this stage that gives the wire its mechanical
characteristics ( traction resistance, bending, torsion and stretching)
that determine the successive quality of the rope.
In every stage of
production the wire is subjected to a series of tests and inspections that
control its quality and efficiency.
These tests normally
consist of a control of the
nominal diameter, traction resistence, and a determination of wire
torsion and bending behaviour.
The galvanized wires undergo a further control on the adherence, weight
and the uniformity of the galvanization.
From the wires, trough the process of
strandinging
the strands are obtained with
which, by means of closing, we obtain the ropes.
Before closing, the
strands undergo a preformation which gives them a spiral form
which they will finally have as a rope.
This preformation has
the following advantages:
- it eliminates the
tensions that occur during the making of the ropes, it allows an easy
manipulation, and decreases the chance of any possible deformations and
allows an easy assembly.
- the cables can be cut
without the need of preventive tying.
- a major guarantee
against the
wires coming out of their
place, avoiding the cutting of the hands of who inspects the ropes and preserves
pulleys and cylinders from scratches and abrasions.
