Sinking RopesKibble Ropes – Ropes used for these duties must berotation resistant, to prevent excessive spin of thekibble or bucket in the shaft.Providing the hoist equipment is suitable, flexible fulllocked coil ropes meet these requirements admirably,and have been used successfully for many years.Where very small diameter sinking drums andsheaves are employed, or where a sheave is fittedabove the kibble to enable two parts of rope tosupport the load, multi-strand rotation resistant ropesare suitable.Bridon’s dedicated Mining Department will bepleased to discuss and recommend the best ropesconstruction for optimum performance on your kibblewinder.Stage Ropes – There are several methods ofsuspending the sinking stage or platform and this cangovern the choice of rope construction.Stage ropes are normally required to act has guideropes for the kibble so resistance to wear is anecessary characteristic. In addition a goodresistance to crushing on the multi-layer drum coilingis required.Full locked coil ropes offer excellent performance onthe correct design of equipment.Friction hoist operating to adepth between 500m and1000mFriction Hoists above 1000mSinking stage winderKibble winderTail/Balance rope6 Strand Ordinary/Langs LayCompound Triangular StrandLangs LayMulti-strand Rotation ResistantFull Locked CoilDyform 6R Ordinary/Langs LayLocked Coil Winding RopesMulti Strand RotationResistantDyform 6R Ordinary/Langs LayCompound Triangular StrandLangs LayMulti-strand Rotation ResistantFull Locked CoilAlternate Lay TriangularStrand Langs LayMulti-strand Rotation ResistantFull Locked CoilMulti-strand Rotation ResistantSuperflexFlat ropeWhere smaller drums and sheaves are employedmulti-strand rotation resistant ropes with relativelylarge outer wires or triangular strands with equalnumbers of left and right hand lay can be used. Withtriangular strand ropes however, problems can beexperienced with controlling the turn if slack ropeconditions occur.Bridon’s dedicated Mining Department will bepleased to discuss and recommend the best ropesconstruction for optimum performance on your stagewinder.Under normal circumstances it is recommended thatropes for both applications, but in particular stageropes, should be manufactured from galvanisedmaterial. However, where higher tensile grades ofwire are required galvanised material is not alwaysavailable. In these cases it is strongly recommendedthat the ropes are regularly cleaned andre-lubricated with emphasis on the evaluation ofcorrosion during examination.30 BRIDON Mining
