Bridon Chairlift Haulage Ropes
6×19 (Bristar Core)
Usually friction driven single endless rope systems for carring people or minerals.
Round Strand or Triangular Strand construction recommended.
Resistance to wear (Single layer, Lang lay).
Crushing: IWRC core could be considered.
Flexibility: Compound construction.
Galvanised as atmospheric conditions under ground can be wet or damp.
Round Strand: Lang Lay, 6X19s, 6X26WS, 6X25F
Triangular Strand:Single Layer Langs Lay, 6X8TS, 6x9TS, 6X10TS
Compound Construction: 6X22TS, 6X23TS, 6X25TS, 6X28TS
ROUND STRAND PERFORMANCE CAN BE ENHANCED BY DYFORMING AS FOLLOW:
Increase breaking loads for same diameter.
Reduced interfaced on drive sheaves and pullies.
Increased resistance to crushing.
Improved fatigue life.
PERFORMANCE CAN BE FURTHER ENHANCED BY INTRODUCING ROUND STRAND WITH THE BRISTAR CORE AS FOLLOWING:
Increases diameter stabitlity and retention.
Increases fatigue life.
