Aluminum EN13411-3 Form A Ferrules

Splicing instructions for Aluminum Ferrules (Form A + B) according to EN 13411-3

1. Allocation ferrule to wire rope
   Select the appropriate ferrule according to our splicing table. Wire rope constructions with a metallic crosssectional area factor of less than 0,283 should not be used. These splicing instructions work for wire rope constructions according to EN 12385-4. Wire rope constructions with a tensile grade above 1960 N/mm² should not be used.
2. Preparation of the rope end
   Ensure that the rope remains in lay after cutting and that no impurities (adhesive tape, etc.) will be within the pressed ferrule.
3. Selection of swaging dies
   Form A should be swaged in approved Universal or Cylindrical dies. Form B should only be swaged in approved and specially marked rounded dies. Ensure that the ferrule code No. and the No. of your swaging die set correspond.
4. Installation and condition of the tooling
   Swaging die faces with corresponding numbers need to be precisely aligned in the die pocket. Dies with worn out cutting edges do no longer assure an accurate swaging procedure according to EN 13411-3 and should be removed from service.
5. Swaging procedure
   The procedure shall be carried out by a competent person trained in ferrule securing. Ferrules 6mm and higher need to be swaged in hydraulic swagers. Smaller sizes might as well be swaged with our hand swaging tools.
   • Feed the wire rope through the ferrule in order to provide the required eye. Return the rope end and form the loop. If no thimble is fitted, the distance from the ferrule to the bearing-point should be at least 15 times the rope diameter.
   • The rope diameter D should be the guide value of how far the dead end of the rope should protrude out of the ferrule before swaging. This needs to be checked after each swaging procedure and adjusted if necessary, according to the type of wire rope, tensile grade and diameter.
   • For satisfactory results you need to first clean and then lubricate the die bore with mineral grease (no oil) before each swaging procedure.
   • Place the ferrule centered and ensure that it is truly vertical within the Die bore.
   • Cease Pressing immediately die faces meet. Do not repress ‘flash’ back into splice.
   • For thimbles without points the gap between the thimble end and the pressed ferrule should be about 1,5 time the wire rope diameter D. For thimbles with points the gap should be 1 time the wire rope diameter D.
   • After swaging the rope ‘dead’end for form A + B should protrude from the pressed ferrule by up to half a rope diameter. For ropes that are severed by annealing process, ensure that the annealed rope portion remains outside the ferrule after pressing.
6. Ferrules after Swaging
   On completion of swaging operation, resultant ‘flash’ must be removed. Swaging dies in good condition permit to either break the ‘flash’ off by hand or with a small hammer. Any residual edge may be filed or otherwise smoothed were required. Every pressed ferrule needs to be checked for correct dimensions and position of the ‘dead’ rope end. The temperature limits when used with a fibre core wire rope are -40° to +100° C The temperature limits when used with a steel core wire rope are -40° to +150° C
7. Marking the ferrule
   If the Ferrule secured Eye Termination (FSET) forms part of a wire rope assembly other than a sling:
   • the ferrule shall be legibly and indelibly marked with the FSET manufacturer’s name, symbol or mark; and
   • the assembly shall be legibly and durably marked with the traceability code identifying the assembly with the certificate in 7.2. of EN 13411-3. For FSET forming part of a sling you will find further details in the standard EN 13141-1.
8. Remark
   Our ferrule-secured system is in accordance with the type testing procedure of EN 13411.3 point 5.1.2. for steel wire ropes defined in EN 12385-4. Ferrule secured eye terminations should be removed from service if badly distorted or if body is reduced to 95 % of its original diameter.

Splicing Instructions for Flemish Eye Sleeves According to EN 13411-3

1. Allocation ferrule to wire rope
   Select the appropriate sleeve according to our splicing table. Standard Flemish eye carbon steel sleeves are recommended for use with 6x19, 6x37 or 6x3, IPS or XIP (EIP), XXIP (EEIP) RRL, FC or IWRC wire rope.
2. Preparation of the rope
   Slide the ferrule down the rope. Un-lay the wire rope. For IWRC rope 3 strands and core in one group and 3 strands in the other group.
   For FC rope un-lay with 3 strands in each group and cut away the fibre core.
   Cross and lay the one group of strands into the other group of strands forming a natural weave. Continue to reweave the group of strands together to form the eye. The remaining tails must be as long as the cylindrical part of the ferrule.
   At the end of the eye collect the tails around the outside of rope dispersing equally and slide the ferrule over the tails and as far up towards the eye as possible.
3. Installation and condition of the tooling
   Swaging die faces with corresponding numbers need to be precisely aligned in the die pocket.
4. Swaging procedure
   A competent person, trained in ferrule securing shall carry out the procedure. Clean and lubricate the bore of the dies with mineral grease (or high pressure oil) before the swaging procedure. Splicing instructions for Flemish Eye sleeves according to EN 13411-3 Put the ferrule in the lower half of the cylindrical die (STEP 1) and close the dies only so far that the original gap between the Die faces reduces by 50 % (STEP 2). Open the dies again and turn the ferrule by 45° to 75°. Re-press again and close up to ¼ of the original diameter (STEP 3). Ensure after STEP 3 procedure that sharp edge flashing is not occurring, then close the Dies. If sharp flash is predicted, repeat STEP 3. Open the dies again and turn the ferrule by 45° to 75° until the dies can be completely closed (STEP 4). During these operations there should not be any pronounced ‘flash’ production. When using the conical dies it is important to position splice centrally in Die bore, in order to permit sleeve elongation in both directions. Repeat the operations in the same way in the conical part (set) of dies.
5. Ferrules after swaging
   The temperature limits when used with a steel core wire rope are -60° to +250° C
6. Marking the ferrule
   Use round corner stamps to a maximum depth of 0.015” (1/64). The area for stamping should be on the side of the sleeve in the plane of the sling eye and no less than 0.250” (1/4) from either end of the sleeve.

Standard Flemish Eye Carbon Steel Sleeves

All sleeves are marked for traceability.

For Flemish eye wire rope splicing made with special processed low carbon steel for better swage ability. Can be stamped for identification after swaging without concern for cracking with the following directions. Use round corner stamps to a maximum depth of 0.015 in. (1/64). The area for stamping should be on the side of the sleeve in the plane of the sling eye, and no less than 0.250 in. (1/4) from either end of the sleeve. NOTE: Standard Sleeves are recommended for use with 6 x 19 or 6 x 37, IPS or XIP (EIP), XXIP (EEIP), RRL, FC or WRC wire rope.

Standard Flemish Eye Carbon Steel Sleeves Specifications

Our carbon steel sleeves are produced with special low carbon seamless steel, alloyed with the right elements to improve their mechanical properties and annealed to allow a high degree of swagability without cracking. For improved corrosion resistance, sleeves can also be offered galvanized. All our sleeves are suited for Flemish eye swaging in demanding rigging, lifting and securing applications. Our sleeves are independently verified against cracking by accredited local metallurgical testing laboratories. The sleeves are tested for composition and compared to others using Energy Dispersive Spectroscopy and Inductively Coupled Plasma. Sleeves are then flattened and checked for evidence of no cracking using X-ray Diffraction. Mil certificates are available upon request.
