Rope Replacement:
Ropes that show severe damage should be replaced, repaired (damaged areas cut out and re-
spliced), or down-rated to other applications. Examples of severe damage in Plasma rope
include (but are not limited to):
a. More than 2 strands severed within a 2-foot segment
b. Fused segment that is no longer flexible (strands not separable)
c. Segment whose diameter is 20% less than other part of the rope
d. Melting on one side that fuses one or more strands together
e. Rope that has lengthened (between reference marks) by more than 10%
Note: It has been found that cleaners/degreasers containing d’Limonene (citrus based cleaners)
can rapidly deteriorate HMPE based ropes. Avoid contact with this chemical.
Each end user will determine through experience which signs of damage are more indicative
of impending failure. (For example, the critical damage mode of a rope that fails in service
might be identified if the location of the break can be traced to damage noted in a prior
inspection.)
Plasma represent a significant technological breakthrough in high strength lifting lines;
however, as with any synthetic fiber rope product, Plasma lines have a much better chance of
meeting expectations when coupled with careful maintenance and periodic inspection.
