In conquence of being not only a steel wire rope producer but also a syn-thetic rope manufacturer, Oliveira has a strong and deep know-how of plastic and its applications. The PPI operation is applied during the Oliveira process in one continuous operation which guarantees a perfect impregnation and equal stress and tension of all the components. Resulting the plastic forms only small braces between the strands so they can keep their flexibility to give in to the relative movements within the rope.
Positive effects:
l Allows a homogeneous stress distribution in the rope
l Improves the structural stability
l Encapsulates the lubricant in the core
l Protects the core from corrosion
Resulting in:
l A longer rvice life
l Keeping its non rotational properties in the most vere conditions l Internal rope protection against corrosive environment
l Favouring outer maintenance

In a non parallel lay rope all wires and strands have different lay length.The high stress concentration at the crossover point leads to an early internal failure. In a parallel lay rope all wires and strands have the same lay length.The linear contact leads to an optimal stress distribution. Furthermore the com-pacted parallel design leads to a higher fill factor and ss lay (non-parallel) stress concentration parallel lay

OLIVEIRA is using the most improved and updated technology in the world (multiroll system) for compacting the strands, resulting in:
l Perfect control of the calibration and of the cross ction
l No outer surface wearing and injuring
l No peel-off of the zinc coating
l No damage of the inner wires, thanks to the gradual lamination l All the properties lead the ropes to the highest performance and resistance to fatigue, when compared with the other usual compacting technologies.cOMPAcTinG

As a standard feature, Oliveira special wire ropes receive intensive lubrication during the production process. This in-process treatment will provide the rope with ample protection against corrosion and it is meant to reduce the friction between the elements which make up the rope as well as the friction between rope and sheaves or drums. This lubrication, however, only lasts for a limited time and should be reapplied periodically.LUBRicATed
