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 the nut (2) to thereby fasten the 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 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.

Abstract: A spool and wedge assembly for securing replaceable cutting teeth or cutting elements to the nose portions of earth moving buckets. The spool and wedge assembly comprises first and second parallel longitudinally extended spool elements, which are transversely displaced apart to engage the aligned side walls of the securing element receiving apertures, and, first and second wedge shaped elements. The wedge and spool elements are interconnected by a longitudinally disposed screw threaded bolt mechanism which is tightened to draw the first and second wedge elements together while forcing the first and second spool elements apart, such that the cutting teeth are locked in position.
