The locking assembly has a block that is able to be positioned and secured in the socket adjacent to the opposing end of the ferrule. The locking block may be a drop-in locking block with a major face that abuts an end of the ferrule to secure it in the socket. The locking block may also have one of a trapezoidal prism, an elongate cam element, or transversely sliding block parts, each of which can abut an end of the ferrule to secure it in the socket. ## Claims ### Claim 1 A dragline socket locking assembly for locking a dragline ferrule attached to an end of a wire rope in a dragline socket into which the ferrule can be received in use, the locking assembly comprising a drop in locking block that is positioned and received in the socket adjacent to a distal end of the ferrule, the locking block comprising a major face which, when the locking block is received in the socket in use, faces the end of the ferrule to secure it in the socket. ### Claim 2 (depends on 1) The locking assembly as claimed in claim 1 further comprising a bolt for extending through aligned holes or passages of the locking block and socket. ### Claim 3 (depends on 1) The locking assembly as claimed in claim 1, wherein once the locking block has been dropped into the socket, the bolt is adapted to extend from one side of the socket, though a hole at that side, through the aligned hole of the locking block and though an opposing hole at an opposite side of the socket to secure the locking block to the socket in use. ### Claim 4 (depends on 3) The locking assembly as claimed in claim 3, wherein a retention pin is provided to extend from a face opposite to the major face, through the locking block and into engagement with the bolt to secure the bolt to the locking block in use. ### Claim 5 (depends on 1) The locking assembly as claimed in claim 1, the assembly being adapted for locking into the socket wherein the ferrule has a component secured thereto such that the ferrule is able to mate with a corresponding formation of the socket when received in the socket in use. ### Claim 6 (depends on 5) The locking assembly as claimed in claim 5, the locking assembly being operable such that the ferrule is first arranged in the socket in the mating engagement prior to locking the ferrule in the socket with the locking assembly. ### Claim 7 (depends on 5) The locking assembly as claimed in claim 5, wherein the ferrule is configured to mate with the corresponding formation of the socket for multiple rotational orientations of the ferrule around an elongate axis of the ferrule. ### Claim 8 (depends on 1) The locking assembly as claimed claim 1, wherein the locking block is configured to be positioned and secured in the socket adjacent to a component that is secured to the end of the ferrule. ### Claim 9 (depends on 8) The locking assembly as claimed in claim 8, wherein the component has a polygon-shaped or U-shaped profile wherein at least two opposing sides of the profile are configured to mate with a corresponding formation in the socket in use. ### Claim 10 (depends on 9) The locking assembly as claimed in claim 9, wherein the polygon-shaped profile of the component has an even number of sides. ### Claim 11 (depends on 1) The locking assembly as claimed in claim 1, further including a tow lug affixed or releasably secured with respect to the distal end of the ferrule. ### Claim 12 (depends on 1) The locking assembly as claimed in claim 1, wherein the wire rope is for use in a dragline. ### Claim 13 (depends on 1) The socket configured for use with a locking assembly as claimed in claim 1. ### Claim 14 (depends on 13) The socket as claimed in claim 13 that forms part of a dragline hoist and/or rigging assembly. ### Claim 15 (depends on 1) A method of securing a ferrule in a socket, the method comprising: locating the ferrule so as to mate with the corresponding formation of the socket; and securing the ferrule against axial movement within the socket using a locking assembly as claimed in claim 1. ### Claim 16 (depends on 1) A system for securing a ferrule in a socket, the system comprising: a socket; a ferrule; the socket comprising a corresponding formation to mate with the ferrule; and a locking assembly as claimed in claim 1. ### Claim 17 (depends on 1) The locking assembly as claimed in claim 1 wherein the locking block comprises one or more side surfaces that can abut with walls and a base of the socket to restrict rotation of the locking block in the socket. ### Claim 18 (depends on 8) The locking block assembly as claimed in claim 8 wherein the locking block is configured to engage the component in use. ### Claim 19 (depends on 18) The locking assembly as claimed in claim 18 wherein the component comprises a tow lug affixed or releasably secured with respect to the distal end of the ferrule.
