26、, Spain, Sweden, Switzerland and the United Kingdom. EN 12385-6:2004 (E) 5 Introduction During the preparation of this standard, it was assumed that negotiations would take place between the purchaser and the manufacturer concerning the intended purpose of the rope. Customers, purchasers and users s

27、hould recognize that ropes for mine shafts are, more often than not, specially designed by the rope manufacturer to meet particular hoisting machinery conditions, and particular attention should be given to the selection of the correct dimension(s) of rope and associated tolerance. Although tables w

28、ith factors for the calculation of breaking forces, nominal rope length masses and outer wire diameters for a number of the more common classes of ropes and tables with physical properties of flat ropes are provided, this part of the standard is not limited to those given, providing all the other re

29、quirements are met. EN 12385-6:2004 (E) 6 1 Scope This European Standard specifies the special material, manufacturing and testing requirements for stranded ropes (with round and/or shaped strands) and flat ropes for use as hoist ropes, stage ropes and balance ropes in mine shafts. It is used in con

30、junction with EN 12385-1 and EN 12385-2. NOTE This European Standard can also be used for ropes in other mining applications, e.g. surface mining. The additional hazards covered by this part of EN 12385 are listed in clause 4. This part of EN 13285 is applicable to ropes for new installations and ro

31、pes that have been manufactured after the publication of this standard. It may also be applied to spare ropes for existing installations 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited

32、at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

37、e centre of a strand comprising a number of small wires manufactured in a separate operation instead of a large disproportional centre wire of a parallel or compound lay construction EN 12385-6:2004 (E) 7 4 List of hazards In addition to the hazards listed in clause 4 of EN 12385-1:2002, where appli

38、cable, the hazard associated with the uncontrolled relative movements between the rope and the driving sheave shall be taken into account (see 5.2.2, 5.2.3 and 5.3.3 with regard to the associated requirements). 5 Safety requirements and/or measures 5.1 General In addition to the requirements given i

39、n 5.2 to 5.7, the requirements shall also conform to those given in EN 12385-1. 5.2 Materials 5.2.1 Wire 5.2.1.1 Before ropemaking Round wires, except those which form a built-up centre shall conform to: a) EN 10264-3 for hoist ropes and stage ropes; and b) EN 10264-2 for balance ropes and the stitc

40、hing wires of flat hoist ropes. For a given rope grade, the tensile strength grades of the wires of stranded round ropes and flat ropes shall not exceed the limits given in Table 1. Table 1 Tensile strength grades of wires in stranded round ropes and flat ropes for a given rope grade Rope grade Tens

42、a tolerance not greater than that of the round wires of the same nominal metallic cross-section. The tensile strength grades of round and shaped wires used to form built-up centres shall be at least 300 N/mm 2 . For flat ropes, all loadbearing wires shall be of the same tensile strength grade. For o

43、uter wires the maximum tensile strength grade shall be 1960 N/mm for bright and class B zinc-coated wires and 1770 N/mm for class A zinc-coated wires. For inner wires the maximum tensile strength grade shall be 2160 N/mm for bright and class B zinc-coated wires and 1770 N/mm for class A zinc-coated

44、wires. The minimum tensile strength grade of stitching wires for flat hoist ropes shall be 1150 N/mm. EN 12385-6:2004 (E) 8 The maximum tensile strength grade of the stitching wires for all flat ropes shall be limited to 75 % of the tensile strength grade of the loadbearing wires. The tensile streng

45、th range shall be 300 N/mm. Reverse bend and torsion requirements are not applicable to stitching wires. The minimum diameter of the wires, excluding any filler wires and round wires for built-up centres, shall conform to Table 2. NOTE The approximate outer wire diameters of round-strand round ropes

46、 can be calculated with the formulae and factors given in Annex D.

In the case of built-up centres, either the individual wires or the centre as a whole shall be tested only for tensile strength. The tensile strength of wires from strands that have been compacted shall be calculated on the basis of their respective nominal diameters before stranding and compacting. The scope of the sampling depends on whether or not the rope manufacturer operates an independently verified quality management system: a) rope ma
