Abstract: An excavation tooth assembly comprising: a first tooth member comprising a body having a first end and an opposite second end that incorporates a socket configured to receive the nose portion of a second tooth member, the first tooth member also comprising laterally facing opposing surfaces, the opposing surfaces and one or more surfaces of the second tooth member defining at least in part a locking space; and a lock which is configured to be inserted into the locking space in an operative position to lock the first tooth member to the second tooth member.

Abstract: A wear assembly for attachment to a digging device, the wear assembly comprising: a wear member arranged to be assembled with the digging device in an assembled condition; and a lock mounted to the digging device, the lock adjustable between an extended configuration and a retracted configuration, the lock comprising at least one locking element that projects outwardly from its mounting in the extended configuration of the lock and is operative to be displaced inwardly from the extended configuration towards its mounting to adopt the retracted configuration of the lock; wherein, with the wear member in the assembled condition with the digging device, movement of the at least one locking element from the extended configuration towards the retracted configuration causes the wear member to be locked to the digging device in the assembled condition.

Abstract: A discharge assembly for a bulk materials rail wagon includes a closure assembly movable to open and close an opening. The closure member includes a cover member and stiffener having a web and flange. In one form an upper surface of the flange is raked. In one form the edge of the stiffener web extends along a concave path to reduce stress concentration in the closure member.

Abstract: A discharge assembly for a bulk materials rail wagon comprises a base incorporating at least one opening to allow gravity discharge of bulk material from the wagon, a closure member associated with the opening and movable to open and close the opening, and a seal to seal between the base and the closure member, the seal being removably mounted and accessible from an underside of the rail wagon.

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: A lock assembly comprising a locking element having; a body having a first locking axis; at least one tab movable relative to the body, the tab movable between a retracted position and an extended position relative to the first locking axis; a locking surface having at least one retaining element; wherein the lock assembly is operative to adopt a locked condition where the at least one tab engages with a respective one of the at least one retaining element to prevent relative movement between the locking element and the locking surface in at least one direction of the first locking axis.

Abstract: A mounting for a replaceable tool on a ground-engaging machine, the mounting having a tool holder having an aperture extending into a body portion of the tool holder for receiving a projecting mounting portion of the tool, the tool holder having an inter-engagement structure for mechanically engaging with a base having a complementary structure, the base being adapted to be fixed to the machine, and the mounting further having retaining means for cooperating with the holder and the tool when installed to retain the holder on the base.

Abstract: A wagon has two side walls, two end walls and a base. At least a portion of one or each side wall has two side wall parts in the form of panels. Each panel has a respective constant wall thickness and is joined together. In some embodiments, the panels can be integrally formed. The side wall panels are also each of a different material thickness. A bridging member in the form of an angled bracket is arranged to interconnect the respective side wall panels by being separately connected to each side wall panel.

Abstract: A coupler for a rail wagon includes a coupler body. The body includes a shank and a head located at an end of the shank. A coupler latch member is mounted to an end of the head. The latch member includes a protruding portion for receipt in a recess of the head. The protruding portion includes at least two adjacent projecting lugs, and the recess includes at least two corresponding adjacent shoulders behind which each lug is located when the latch member protruding portion is received in the head recess.
