LIFTING SLING FITTINGS FOR WIRE ROPE
      FOR WIRE ROPE             SWIVELS







                                          Applications




                                         Thrust bearing swivels are used to prevent wire rope or
                                        chain from transferring their normal twisting motion to

                                                                             ®
                                      are not designed to rotate under load, but are intended
                                     as positioning devices only. For rotation under load, thrust
                                    bearing swivels should be used. Our swivels can be supplied

                                with two types of end fittings.

                                Green Pin  swivels (eye-eye/ jaw-eye) are drop forged. Green Pin  thrust bearing swivels are machined from
                                carbon steel. The range of thrust bearing swivels we supply are fitted with grease nipples to ensure long life
                                and smooth operation. The greasing schedule must be adjusted to the frequency and intensity of use.
                                Each swivel is generally marked with:
                                •  Working Load Limit                   - e.g. 2.4 t
   3 .1                         •  manufacturer’s symbol                - e.g. GP
                                •  traceability code                    - e.g. A1
                                •  CE conformity code (conformité Européenne)   - CE

                                Instructions for use

                                Swivels should be inspected before use to ensure that:
                                •  all markings are legible;
                                •  a swivel with the correct WLL has been selected;
                                •  the bolt, nut or any other locking system cannot vibrate out of position;
                                •  swivels are free from nicks, gouges and cracks;
                                •  swivels are not distorted or unduly worn.
                                Also:
                                •  swivels must be used for in-line lifting only;
                                •  swivels may not be heat treated as this may affect their WLL;
                                •  never modify, repair or reshape a swivel by machining, welding, heating or bending as this may affect
                                  the WLL.

                                The WLL should be applied in-line. Avoid overloads. Side loading is not allowed since the swivels are not
                                designed for this purpose. Never replace a swivel pin or nut with a pin other than the one designed for
                                the purpose, as otherwise the swivel may not be suitable for the load imposed. Swivels must be regularly
                                inspected in accordance with the safety standards given in the country of use. This is required because
                                the products in use may be affected by issues such as wear, misuse and overloading, which may lead to
                                deformation and alteration of the material structure. Inspection should take place at least every six months
                                and more frequently when the swivels are used in severe operating conditions.
