Abstract: A self-drilling rock bolt assembly (1) including a drill head mechanism (100) and a fluid delivery system (300) operatively associated with each other and adapted in use to secure a self-drilling rock bolt (200) into a strata (2). The rock bolt (200) having a shaft (210) having a cutting end (220) and a driving end (230). The drill head mechanism (100) having a bolt coupling portion (130) to releasably engage with the driving end (230) of the rock bolt (200). Wherein rotation of the bolt coupling portion (130) rotates the rock bolt. A central hollow portion (111) provides access to a fluid connection port (232) of the rock bolt and a nut coupling portion (120) releasably engages with a nut element (250) located on the shaft of the rock bolt. Wherein rotation of the nut coupling portion rotates the nut element.

Abstract: A lightweight tender comprising a hull constructed from substantially a single piece of composite material and a retractable pillar attached to the hull, wherein the retractable pillar defines a longitudinally extending channel. A retractable carbon fiber bimini cover is pivotingly attached to the retractable pillar, and defines a top deck when the pillar is retracted, and defines a bimini top extended. A first end of a brace is hingedly attached to the bimini cover and a second end of the brace travels within the longitudinally extending channel of the retractable pillar such that the angle between the bimini cover and the retractable pillar increases as the brace travels distally within the longitudinally extending channel.
