Abstract: A coupling assembly for releasably attaching a ground engaging tool to earth moving equipment comprises a boss arrangement mounted onto a lip of an excavation implement of the equipment relative to an edge of the lip. The coupling assembly also comprises a bolt comprising a threaded portion and a flange. The threaded portion is received by a threaded aperture in the boss arrangement such that relative rotation between the bolt and boss arrangement causes rearward movement of the bolt and flange away from the edge. A retainer is removably insertable between the flange and a bearing surface of the tool readward the flange. The rearward movement causes the flange to engage the retainer and the retainer to engage the bearing surface such that the bolt goes into compression and urges the tool toward the edge.

Abstract: The present invention provides a protective shroud assembly for use on a wear edge of earthmoving machinery. The shroud assembly comprises a shroud adapted to be received with respect to the wear edge. The shroud has a wear region at a second end thereof which is adapted to engage the earth as the wear edge moves therethrough. The shroud assembly also comprises a locking means having a portion which is rotatably received in the shroud such that the shroud is releasably secured with respect to the wear edge when the locking means is in a locked position.
