This document specifies the minimum requirements for solid thimbles made of steel or cast iron for terminations of stranded steel wire ropes. This document is applicable to ferrule-secured terminations with solid thimbles in combination with ferrules (see EN 13411-3), that have an efficiency factor KT of at least 0,9, and to spliced terminations with solid thimbles (see EN 13411-2), that have an efficiency factor KT of at least 0,8, which are used as accessories for steel wire ropes, such as slings or wire rope assemblies, having a lifting, lowering or load-bearing effect in hoisting equipment. Examples of designs of solid thimbles which meet the requirements of this standard are given in informative Annexes B and C. Round thimbles (thimble with rotational symmetry around the bore) are not subject to this document. This document is applicable to ferrule-secured terminations that are manufactured after the date of publication of this document. Hazards that are dealt with in this document are listed in Clause 4.
