Abstract: Disclosed is a system and method for determining a wear or operational characteristic regarding an apparatus. The method includes: determining a position data of at least a portion of the apparatus, by analysing two-dimensional image data from each of a plurality of image sensors located to capture image data of the apparatus, or part thereof, and calculating a physical or operational characteristic using the position data.

Abstract: Disclosed herein is a mill liner assembly for a grinding mill, comprising: a mill liner which comprises a wear surface and an opposite inner surface that is arranged in use to be mounted in opposed relation to an interior surface of a shell of the grinding mill, a liner sensor which is embedded within the mill liner; and a control or power arrangement configured to control or power the liner sensor, the control or power arrangement being also embedded in the mill liner.

Abstract: A lip for an excavation bucket, the lip comprising: an upper and a lower surface that extend to a digging edge; and a plurality of mounting sections for mounting shrouds to the lip to protect the digging edge against wear, at least one of the mounting sections comprising first and second bearing surfaces on one of the upper or lower surfaces of the lip and configured to have a shroud bear against when mounted to the mounting section, wherein the first and second bearing surfaces are inclined with respect to one another.

Abstract: A member for assembly with other members in an assembled condition to form an excavation bucket, the member forming at least part of one of the walls of the bucket when in its assembled condition, the member comprising a body having a forward edge; a rearward edge; opposite inner and outer surfaces that extend between the edges; a first portion of the member being thicker between its inner and outer surfaces than a second portion of the member, the first portion being disposed forward of the second portion.

Abstract: An excavation tooth assembly comprising: a first tooth member including a nose portion; and a second tooth member comprising a body having opposite first and second ends and a socket extending into the body from the first end to finish at an end wall, the first and second tooth members arranged in an assembled condition where the nose portion of the first tooth member is received within the socket of the second tooth member, wherein the tooth members being configured in the assembled condition with opposed surface portions of the socket located towards the second end of the second tooth member bearing on the nose portion of the first tooth member and clearance gaps are provided between opposed surface portions of the socket located towards the first end of the second tooth member and the nose portion.

Abstract: A load equaliser for supporting a drag line bucket from first and second cables is disclosed. The load equalizer has a main body having a central portion and side portions providing respectively first and second clamps for clamping end portions of the first and second suspension cables. A rotatable mounting is provided in the suspension central portion of the main body. A link body is suspended below the main body and connected thereto through the rotatable mounting whereby freedom of relative rotational motion is provided at least about an axis substantially at right angles to the direction between the clamps. The rotatable mounting is in a zone extending substantially between the clamps.

Abstract: A spreader component for use with a dragline excavator. Two dumpblocks are connected to the component in a spaced apart manner. The spreader component may include an in-use upper coupling arrangement for enabling coupling of the component to a hoist link of the dragline, at least first and second spaced apart in-use anterior coupling arrangements each for enabling coupling of the component to a respective dump block, and at least first and second spaced apart in-use lateral coupling arrangements each for enabling coupling of the component to a respective lift chain for a bucket of the excavator. An elongate connector may connect each lift chain to a respective lateral coupling arrangement in use.

Abstract: A swivel link for dragline rigging, the swivel link having three connection points interconnected by connecting arms, the connecting arms defining an interior cavity of the swivel link
