21、dentifying the different types of pulling eyes which are used to facilitate the installing and re-reeving of ropes on a machine.Such pulling eyes, sometimes referred to as beckets, are often used when another rope is required to pull the new rope into place.4DIN EN ISO 16841:2014-07 EN ISO 16841:201
22、4 (E) 1 ScopeThis International Standard identifies the different types of pulling eyes prepared at, or attached to, a steel wire rope end for connection to another rope when installing a new rope or re-reeving an existing rope on a machine.This International Standard also specifies the minimum requ
23、irements for pulling eyes, including their geometry, strength, maximum line pull to which the pulling eye is intended to be subjected and information for use to be provided by the manufacturer.The pulling eyes covered by this International Standard are not intended to be subjected to a load when the
24、 machine performs a service operation.This International Standard applies to those pulling eyes prepared at, or attached to, ends of steel wire ropes conforming to ISO 2408 and ISO 10425.This International Standard does not apply to steel wire ropes with fibre cores.This International Standard does
25、not cover those separate end connection accessories, which slide over the end of a rope and comprise an eye- and tubular-type braided rope, often referred to as a “wire rope stocking” or “cable sock”.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in th

33、uctions for each type of pulling eye that they intend to produce. These instructions shall, at least, as applicable to the type of pulling eye, include the following aspects: the rope types and diameters for which the pulling eye type is suitable; method for preparing the rope end; matching the pad
34、eye, modified eyebolt or chain link to the rope; method for welding component to the rope; method for forming the eye or loop; method for preparing the tapered section; inspection criteria.The manufacturers instructions shall be supported by a written declaration stating that the system has passed t
35、he type testing requirements of 4.3.Pulling eyes shall be made in accordance with the manufacturers instructions.In the case of the welded components attached to the rope end, the welding shall be performed by a qualified person.Qualification procedure shall be performed as defined in 4.5.Requalific
36、ation is not required, provided a minimum of three component welds are made during any 12-month period.6DIN EN ISO 16841:2014-07 EN ISO 16841:2014 (E) 4.2 Geometry4.2.1 Flexible-type pulling eye made from the centre strand of the coreThe dimensions of the eye or loop shall be such that it shall be p
37、ossible for its shape to change sufficiently enough to pass the completed pulling eye through an aperture of equivalent size to the diameter of the rope which is to be installed.The internal length of the eye or loop, as manufactured, shall be at least three times the diameter of the rope.An illustr
38、ation of such a completed pulling eye is given in Figure 1.Figure 1 Completed flexible pulling eye made from the centre strand of the core4.2.2 Flexible-type pulling eye made from the steel core itselfThe internal length of the eye or loop, as manufactured, shall be at least five times the diameter
39、of the rope.An illustration of such a completed pulling eye is given in Figure 2.NOTE It is not usually possible for a pulling eye made from the steel core itself to be passed through an aperture of equivalent size to the diameter of the rope.Figure 2 Completed flexible pulling eye made from the ste

42、bolt at its base shall be such that it will allow for a continuous fillet weld to be applied around its periphery in the first welding pass to secure it to the rope end.The maximum dimensions of the pad eye, modified eyebolt or chain link shall be no greater than the diameter of the rope.An illustra

44、pulling eye incorporating welded chain link4.2.5 Semi-rigid type pulling eyeThe selected diameter of the looped short length of rope shall be such that it protrudes above the parent rope diameter when inserted into the gusset between the outer strands of the parent rope prior to the compaction of th

46、 and pulling eye type, the following shall apply. Where the pulling eye design follows a mathematical progression throughout a given size range, rope diameters shall be selected for testing to represent the upper and lower quartiles of that range. Where the pulling eye does not follow a mathematical
47、 progression through a size range, each rope diameter within that range for which the pulling eye is designed shall be selected for testing. For rigid-type pulling eye, each rope diameter within the range for which the pulling eye is designed shall be selected for testing.NOTE Rope of the same diame
48、ter, but of different construction e.g. 8 19S and 8 36WS can contain significantly different wire diameters. Welding settings, electrode size, etc. suited to one construction will not necessarily suit the other construction, hence the need for process validation on each rope within the range.4.3.2 M
49、inimum breaking force of pulling eye (Fp,e,min)The pulling eye manufacturer shall determine the minimum breaking force of the pulling eye, Fp,e,min, and indicate the value on the certificate of compliance (see 6.2).In the case of the flexible-type pulling eyes, the manufacturer shall take account of the strength of the centre strand of the core or the core itself, as applicable, and also the efficiency of the Flemish eye of the core strand or the
