24、rnational Standard identifying 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.

25、eserved vBS EN ISO 16841:2014BS EN ISO 16841:2014Steel wire ropes Pulling eyes for rope installation Types and minimum requirements1 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
26、installing a new rope or re-reeving an existing rope on a machine.This International Standard also specifies the minimum requirements 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
27、 the manufacturer.The pulling eyes covered by this International Standard are not intended to be subjected to a load when the 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 an
28、d ISO 10425.This International Standard does not apply to steel wire ropes with fibre cores.This International Standard does 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 s
29、tocking” or “cable sock”.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable to its application.
