EN 12385-8:2002 (E)3ForewordThis document (EN 12385-8:2002) has been prepared by Technical Committee CEN/TC 168, “Chains, ropes,webbing, slings and accessories – Safety”, the secretariat of which is held by BSI.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest byApril 2003.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EC Directive(s).For relationship of this Part with EU Directives, see informative Annex ZA, which is an integral Part of thisdocument.The other Parts of EN 12385 are:Part 1: General requirementsPart 2: Definitions, designation and classificationPart 3: Information for use and maintenancePart 4: Stranded ropes for general lifting applicationsPart 5: Stranded ropes for liftsPart 6: Stranded ropes for mine shaftsPart 7: Locked coil ropes for mine shaftsPart 9: Locked coil carrying ropes for cableway installations designed to carry personsPart 10: Spiral ropes for general structural applicationsPart 1 provides the general requirements of Parts 4 to 10.This is the first edition of this Part.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.



EN 12385-8:2002 (E)4IntroductionThis Part of this European Standard has been prepared to be a harmonized standard to provide one means ofcomplying with the essential safety requirements of the Directive relating to cableway installations designed to carrypersons.During the preparation of this standard, it was assumed that a negotiation would take place between the purchaserand the manufacturer concerning the intended purpose of the rope.Although tables of breaking forces and masses are provided for a number of the more common classes, diametersand rope grades, this Part of this standard is not limited to those given, providing all of the other requirements aremet.1 ScopeThis Part of this European Standard specifies the particular materials, manufacturing and testing requirements forstranded steel wire ‘hauling’ and ‘carrying-hauling’ ropes for cableway installations designed to carry persons.The particular hazards covered by this Part are identified in Clause 4.The rope grade is limited to 1960.Minimum breaking forces for the more common classes, sizes and grades of rope are provided in tables 2, 3 and 4.Stranded tension ropes and ski-tow ropes are covered by EN 12385-4.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. For datedreferences, subsequent amendments to or revisions of any of these publications apply to this European Standard onlywhen incorporated in it by amendment or revision. For undated references the latest edition of the publication referredto applies (including amendments).EN 10264-3, Steel wire and wire products – Steel wire for ropes – Part 3: Cold drawn and cold-shaped non-alloyedsteel wire for heavy duty applications.EN 12385-1:2002, Steel wire ropes – Safety – Part 1: General requirements.EN 12385-2, Steel wire ropes – Safety – Part 2: Definitions, rope designation and classification.prEN 12408, Safety requirements for cableways for passenger transportation by rope - Quality control.DIN 21258:1986, Preservative compounds for koepe friction drive winding ropes in mining – Safety requirementsand testing.DIN 53521, Determination of the behaviour of rubber and elastomers when exposed to fluids and vapours.ISO 2592, Determination of flash and fire points – Cleveland open cup method.



EN 12385-8:2002 (E)53 Terms and definitionsFor the purposes of this European Standard, the terms and definitions in EN 12385-2 apply.4 List of hazardsIn addition to the hazards identified in clause 4 of Part 1, the hazard associated with uncontrolled relativemovement between the rope and the driving sheave, when applicable, is also identified.5 Safety requirements and/or measures5.1 GeneralIn addition to the requirements given in 5.2 to 5.7, the requirements shall also conform to those given in Part 1.The manufacturer shall also comply with EN 12408.5.2 Materials5.2.1
WireWires before ropemaking shall conform to EN 10264-3.The tensile strength grades of the wires shall be subjected to the limits given in Table 1.Table 1 — Wire tensile strength grades excluding centre and filler wires for given rope gradesRope gradeWire tensile strength grade, N/mm2MinimumMaximum1570137017701770157019601960177021605.2.2 CoreThe core shall be one of the following typesa) fibre;b) solid polymer;c) non-magnetic metallic covered with solid polymer;d) steel covered with solid polymer;e) steel, as an independent wire rope (IWRC) or wire strand (WSC).5.2.3 LubricantThe properties of the lubricant shall conform with the requirements of annex A.NOTEThe purchaser should specify any particular lubricant (see Introduction).



EN 12385-8:2002 (E)65.3 Rope manufacture5.3.1 LubricationLubrication shall be generally limited to the strands.NOTEThe purchaser should specify any particular lubrication requirements (see Introduction).5.3.2 ConstructionThe construction shall be either a)
one of those covered by the three classes given in Tables 2 to 4; or b)
another single layer rope construction as specified by the manufacturer and covered by the respectiveclasses in EN 12385-2.NOTEStrands can be compacted.5.3.3 Rope gradeThe rope grade shall be not less than 1570 or higher than 1960.NOTEThe rope grades are generally 1570, 1770 or 1960 although intermediate rope grades can also be specified.For the more common classes of ropes, refer to Tables 2 to 4, the rope grade shall be used in the calculation ofbreaking force. (See annex C).5.3.4 WavinessRopes shall be measured for waviness in accordance with annex B. The amount of waviness measured over a lengthequivalent to 3 rope lay lengths shall be not more than 0,01 d + 0,2 mm.5.4
Diameter5.4.1 TolerancesWhen measured in accordance with 6.7 the actual diameter shall be within + 1 % and + 5 % of the nominal diameterwith the rope under load on the closing machine.5.4.2 Differences between diameter measurementsThe difference between any two of the four measurements taken in accordance with 6.7 and expressed as apercentage of nominal diameter shall not exceed 4 %.



EN 12385-8:2002 (E)75.5 Breaking forceOnly the minimum breaking force shall be specified as the breaking force.The values of minimum breaking force for the more common classes and grades of ropes shall not be less thanthose given in Tables 2 to 4. For intermediate rope diameters, the values shall not be less than those obtained fromthe formula given in annex C using th
