Many of our wire ropes
are manufactured using either the Strand Compaction- or the Swage Compaction
process. Here are the differences:
STRAND COMPACTION
This process is applied to the strands NOT to the rope. The ready made
strands are forced through a series of rollers which compress the strand
and shape the individual wires to have a flat outer surface. The advantages
are:
• increased strength
• less wire interlocking on multiple layer drums
• less contact pressures onto sheaves and drums
SWAGE COMPACTION
This process is usually applied to wire rope which is made using the
double parallel manufacturing method, or where the rope core is plastic
coated. This process is applied after the rope has been manufactured and
compresses the entire rope circumference. Individual surface wires are
shaped flat as well as closing strand gaps. The advantages are
• increased strength
• transforming the entire rope into a more 'round' shape
• less wire interlocking on multiple drums
• less contact pressure onto sheave and drums
• embedding strands into plastic coated cores
• achieve tighter diameter tolerances
• reduces constructional rope stretch to near zero |
