Figure 3-33.—Fold back eye and pressed metal sleeve.The tucked eye with the pressed metal sleeve isalmost 100 percent efficient; however, the tucked eyeand serving in group 2 can develop only 70 percent ofthe strength of the rope and tend to come free as therope unwinds. As the rope untwists, the tucks in theeye begin to pop free.All eye spices in group 2should have a least five tucks, and the complete spliceshould be carefully and tightly wrapped with a wireserving to cover the whole splice.The fold back eyes and pressed metal sleeves ingroup 3 are fabricated by bending the rope to the eyedimension required and securing the free or dead endof the rope against the live portion of the rope bymeans of a steel or aluminum sleeve set in place underpressure. Improper swaging or split sleeves used withfold back eye splices (fig. 3-34) can result in completefailure without warning.It is highly recommendedthat these eye splices never be used for overheadhoisting operations.An alternate method of forming a soft eye in theend of a wire rope without the use of permanentsplicing is fabricating a flemish eye splice (MolleyHogan). The eye is simple to form, requiring aminimum amount of tools, and does not require use ofa splicing vise. The flemish eye develops 90 percentof the breaking strength of the wire rope.To form a flemish eye (fig. 3-35), unlay the ropestrands 3 to 4 inches longer than twice thecircumference of the eye size desired. The wire ropecore can be cut out or laid in one section of the wire.A simple overhand knot is made, letting the strandslay together and adjusting the eye to the desired size.Bend sections of the strands through the eye so thatthe strands re-lay into position to form the rope.Continue until the eye is completed. Secure the bitterends of the strand to the rope with lashing, seizing, ora wire clip to prevent unlaying of the rope. Before thesling can be put into use, it must be proof-tested andtagged.Proof-TestingAll field-fabricated slings terminated bymechanical splices, sockets, and pressed and swagedFigure 3-34.-Fold back sling failure.3-28
