LIFESPAN, OBSOLESCENCE AND COMPONENT INSPECTION
Friction Hitch Cord
Ocean Polyester
Ocean Polyester is a kernmantle construction, more speci-
fically a double braid i.e. a cover is braided over a braided
core. Both layers carry the load. In doubled (running) rope
systems using a friction hitch as the adjuster, the cover of
the friction hitch experiences abrasion and considerably
higher temperatures compared to the core. For this reason
heat resistant Aramid fibres are included in the cover.
Friction Hitch cord is a consumable wear part. Expect to see signs of wear. Expect to replace
friction hitch cord regularly. Regular monitoring is essential e.g. pre-use checks, weekly inspec-
tions, thorough examinations (consult national legislation for interval) and after exceptional cir-
cumstances.
Concentration of high temperatures, in association with abrasion, is likely to damage the Polyes-
ter fibres (red) before the Aramid fibres (straw). Inspect all fibres for damage. Look especially at
the section of cord used to make the top coils of the friction hitch.
Hitch function becomes less tactile as the Polyester fibres are removed, resulting in a friction
hitch that feels different i.e. it brakes and releases more abruptly. This is an advanced indicator
of wear, safety margins are still high. Replace friction hitch cord at this point i.e. when function
changes not when safety margins are low. Reckless climbing, characterised by rapid descents,
will reduce product lifespan dramatically.
The core of Ocean Polyester is braided polyester. Check for lumps, other irregularities and stiff-
ness during regular tactile inspections.
Inspect the stitched terminations. Ensure that the stitching is intact and protected by its original
cover sleeve. Check for cut, distorted or worn stitching. Inspect the eye for fibre damage. Re-
place the cord if there is any damage to the stitching.
Retire the friction hitch cord if:
any concern arises about abrasion or any other material damage;
ƒ
if the cover is ruptured;
ƒ
if it has been used to arrest a fall.
