Abstract: A lock assembly (1) including a main body (4) and a protruding member (5). The protruding member (5) is biased to normally protrude outwardly of the main body (4) by a biasing component (6), which is formed of rubber or like material. An operating mechanism, operated by a key (9) effects movement of the protruding member (5) between a protruded or locked position, and, a withdrawn or unlocked position.

Abstract: A fastening assembly (1) for releasable securement of first and second components. The assembly includes: a nut (2), having a threaded bore and a shaped outer surface; a retainer (3), associated with said first component, including a slot which is of complementary shape to said outer surface of said nut (2), and which is adapted to receive and retain said nut (2) therein; and, a bolt (4), having a head and a threaded shaft, which is adapted to engage said second component, and be secured to said nut (2) to thereby fasten said first and second components together. The fastening assembly (1) is particularly useful to secure a wearable edge to a bucket of a mining, earthmoving, agricultural or like machinery.

Abstract: A tail extension (1) adapted to be pivotally attached (2) to a load carrying container (3). Tail (1) pivots between a first position substantially outwards from a floor of the container, and a second position upwardly inclined relative to said floor. Tail (1) may be formed as one or a plurality of sections which move individually or cooperatively. Tail (1) may be pivotally connected (2) adjacent the floor of container (3) by a hinge allowing free movement and/or may be displaced by a drive means (e.g. hydraulic, mechanical, pneumatic). By tail (1) being able to pivot when contracting the ground, tail (1) and container (3) are not going to be subjected to undue forces which may damage tail (1) or container (3). When being transported, tail (1) acts as an extension to improve the load carrying capacity of the container by extending outwardly, or, can be displaced upwardly by a drive means to form a rear wall on the container.

Abstract: A hydraulic fastening device for securement of two components, each component having an orifice at least partly therethrough adapted to be coaxially aligned, the fastening device including a body member adapted to be inserted within the orifice of each component when coaxially aligned. The body member includes a main body section and a hydraulic manifold section with a fluid conduit within at least the manifold section and containing a fluid therein. The device further includes at least one moveable protrusion in fluid contact with the fluid, adapted to protrude from the manifold section; and control means to control the movement of each protrusion means. The arrangement is such that, upon operation of the control means, each protrusion is moved between a protruding position and a retracted position and when in the protruding position, the two components are adapted to be fastened together.

Abstract: A hydraulic fastening device, for securement of two components, for example, securement of teeth to a bucket on earthmoving or mining equipment. Each component has an orifice therein adapted to be substantially aligned. A body member is inserted in the aligned orifices. A control device is then operated to move at least one protrusion to protrude from the body and to fasten the components. This is achieved by hydraulic operation and connection of a fluid conduit between the control device, e.g. a grease nipple, and the protrusions.
