27、 as stated in EN 1070. This European Standard has been prepared to provide a means of conforming with the essential requirements of the Machinery Directive and associated EFTA regulations. Purchasers ordering to this standard are advised to specify in their purchasing contract that the supplier oper

28、ates an independently verified quality assurance system to ensure themselves that products claimed to comply consistently achieve the required level of quality. The wedge sockets concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this

29、 document. When provisions of this Type C standard are different from those which are stated in Type A or B standards, the provisions of this Type C standard take precedence over the provisions of the other standards, for asymmetric wedge sockets that have been designed and produced according to the

30、 provisions of this Type C standard. DIN EN 13411-6:2009-04 EN 13411-6:2004+A1:2008 (E) 5 1 Scope This European Standard specifies the minimum requirements, for asymmetrical wedge socket terminations for stranded steel wire ropes. Examples of the construction and sizes of two separate designs of asy

31、mmetric wedge sockets are given in informative annexes A and B. The informative annex C gives recommendations for safe use and inspection. This European Standard deals with all significant hazards, hazardous situations and events relevant to asymmetric wedge sockets for terminations for steel wire r

32、opes, when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. This standard applies to terminations of steel wire ropes with asymmetrical wedge sockets which are manufactured after the date of its publication. This standard does not cover rope fatig

41、s and events, as far as they have been dealt with in this standard, identified by risk assessment as significant for this type of steel wire rope termination which require action to eliminate or reduce the risk. In particular hazards caused by accidental release of a load, or release of a load due t

42、o failure of an asymmetric wedge socket puts at risk, either directly or indirectly, the safety or health of those persons within the hazard zone. Errors in the fitting of accessories can also lead to premature failure and this standard contains dimensional requirements to allow correct fit. Table 1

43、 contains those hazards that require action to reduce risk identified by risk assessment as being specific and significant for asymmetric wedge sockets.

45、Geometry of wedge and socket body Asymmetric wedge socket terminations for ropes shall conform to the following geometrical criteria (see Figure 1): The longitudinal axis of the live portion of the rope shall be perpendicular to the longitudinal axis of the pin. The difference between the wedge angl

The clamping length between socket body and the wedge in contact with the live portion of the rope shall be a minimum length (P) equal to

47、4,3 times the nominal rope diameter. The rope groove in the socket body and the wedge shall not exhibit protrusions, marks or casting joints that would affect the intimate contact with the rope.
