Abstract
A ferrule 10 for attachment to an end of a wire rope R is disclosed. The ferrule comprises an open end 12 into which the end of the wire rope can be received for securement in the ferrule. The ferrule also comprises an end 14 that opposes the open end. The ferrule further comprises an axis Ax extending between the open and opposing ends. The ferrule is configured at or around at least one of the open and opposing ends such that the ferrule is able to mate with a corresponding formation of a socket 50 into which the ferrule can be received in use. Also disclosed is a socket 50 adapted to the ferrule, and a mechanism for axially locking the ferrule in the socket.
Claims19
A ferrule for attachment to a wire rope end, the ferrule being configured for use with a socket that forms part of a dragline hoist and/or rigging assembly, the ferrule comprising:
- an open end into which the end of the wire rope can be received for securement in the ferrule;
- an end that opposes the open end;
- and
- an axis extending between the open and opposing ends;
- wherein the ferrule comprises a formation at or around at least one of the open and opposing ends, the formation configured to engage with a corresponding formation of the socket such that, if the ferrule is subjected to a rotating or twisting force within the socket, the formation interferes with the corresponding formation to prevent further rotation or twisting of the ferrule in the socket.
A ferrule for attachment to a wire rope end, the ferrule being configured for use with a socket that forms part of a dragline hoist and/or rigging assembly, the ferrule comprising an open end into which the end of the wire rope can be received for securement in the ferrule, wherein the open end comprises a formation that is configured to engage with a corresponding formation of a socket such that, if the ferrule is subjected to a rotating or a twisting force within the socket, the formation interferes with the corresponding formation to prevent further rotation or twisting of the ferrule in the socket.
A dragline hoist and/or rigging assembly comprising a ferrule for attachment to a wire rope end, and a component secured to a distal end of the ferrule, the component having a polygon-shaped or U-shaped profile wherein at least two opposing sides of the profile are able to engage with a corresponding formation in a socket in use such that, if the ferrule is subjected to a rotating or twisting force within the socket, the at least two opposing sides of the profile interferes with the corresponding formation to prevent further rotation or twisting of the ferrule in the socket.
A method of securing a ferrule in a socket, the ferrule comprising a formation at an open end into which an end of a wire rope can be received for securement in the ferrule;
- an end that opposes the open end;
- and an axis extending between the open and opposing ends;
- wherein the ferrule is configured at or around at least one of the open and opposing ends such that the formation is configured to engage with a corresponding formation of the socket such that, if the ferrule is subjected to a rotating or twisting force within the socket, the formation interferes with the corresponding formation to prevent further rotation or twisting of the ferrule in the socket and wherein the method comprises:
- locating the ferrule so as to mate with the corresponding formation of the socket;
- and securing the ferrule against axial movement within the socket.
