摘要

An anchoring device (10; 110) for use on a roof having a plurality of trusses (12) with external covering means (14; 16; 22) is described. The anchoring device (10; 110) includes truss attachment means (26) for securing the anchor to a truss (12) and a roof anchor (28) which is coupled to the truss attachment means (26) and which passes through the roof covering (14; 16; 22) to provide an anchor point. The truss attachment means (26) has upper and lower plates (30; 32) for engaging with respective upper and lower faces of the truss (12). The plates are connected by side members (34; 36) for location to respective sides of the truss (12), the spacing between the side members (34; 36) being adjustable to accommodate trusses of different widths. The anchor point can be provided by an eye (52) or a hook (66) or both and a ladder or crawler board (116) or scaffolding frame (202; 218) can be secured to the anchoring device by the eye or hook to facilitate a safer working environment. Embodiments of the invention are described.
