Abstract
Method and apparatus for securing swage sleeves upon a wire rope having a sling spliced thereon. The apparatus includes semi-automatic mechanisms for insuring the full and efficient fastening of the swage sleeve upon the splice in preparation for swaging, thereby effecting a stronger wire rope sling.
Claims9
Apparatus for securing swage sleeves upon a wire rope having a splice thereon configured to form a sling at the end of such wire rope, said apparatus comprising:
- a supporting structure;
- means movably mounted on said supporting structure for securing and capturing a swage sleeve, said securing and capturing means being configured to permit the passage of an end of wire rope therethrough such that such end of such wire rope may be passed through such swage sleeve to be spliced and formed into a sling loop;
- means positioned on said supporting structure for clamping a portion of such wire rope on the other side of said securing and capturing means from such wire rope sling loop;
- and
- means for automatically forcibly moving said securing and capturing means, and such swage sleeve contained therein, in a direction away from said clamping means and toward such sling loop on such end of the wire rope for forcing the spliced portion into such swage sleeve such that a stronger splice is realized when such swage sleeve is swaged.

A method of automatically securing swage sleeves on wire rope sling splices, said method comprising:
- fitting a swage sleeve within a holder complementarily configured relative to the swage sleeve;
- threading the end of a wire rope, intended to be spliced into a sling, into the holder and through the swage sleeve contained therein;
- forming the wire rope end into a spliced sling;
- clamping the wire rope at a point on the opposite side of the holder from the spliced sling;
- automatically moving the holder, and the swage sleeve contained therein, in a direction away from the point at which the wire rope is clamped and toward the splice formed on the sling, thereby forcing the swage sleeve onto the splice of the wire rope;
- and
- releasing the swage sleeve from the holder and unclamping the wire rope in preparation for a swaging operation.
