Ropes with compacted strands are special ropes produced with strands with high filling coefficient.
Compacting process deforms strand's wires so that they fill all existing empty spaces between wire and wire.
As result compacted strand has a bigger metallic section and uniformly smooth surface.
Moreover deformation of wires extends surfaces in contact and as consequence reduces pressures during normal work of the rope.
Combined effect of compacting process is that compacted ropes have got higher breaking load, higher resistance to fatigue, to abrasion and to pressures of pulley, drum, etc.
