Efficiency ratings of end terminations
 
This page lists several types of end terminations used for overhead lifting applications.

All efficiency ratings are based on the difference between the actual breaking strength of a rope and the attained breaking strength with that specific fittings. The only fitting which will attain a 100% efficiency are spelter sockets; provided they are properly attached.
  ALL other fittings are swaged or clamped onto the rope. The swaging or clamping process compresses the rope to varying degrees causing a slight loss of strength. Some publications refer to '100%' efficiency with swaged sockets. Bear in mind, that most wire ropes have an actual breaking strength up to approximately 5%-15% HIGHER than the breaking strength listed in catalogue tables. With other words: a fitting having an efficiency rating of 90% may very well develop 100% of the rope's CATALOGUE breaking strength because the rope's ACTUAL breaking may very well be 5%-15% higher.
 
     
(1) Use only with 6-strand wire rope.
(2) ONLY when applied with EN 14311 sleeves and fabrication method.
(3) Fabrication efficiency depends on fitting dimensions. Ask for information on UNI-LOC™ Assemblies.
