摘要

A dead-weight anchor device 1 for securing a line 2 to a person working at height comprises a flexible-walled container 4 with an internal volume that may in 5 uses be inflated with a quantity of water to provide an anchoring dead-weight and subsequently deflated by letting the quantity of water escape from the container 4 when not in use. The container 4 has at least one attachment 36 for the line 2. The container 4 has a plurality of flexible walls10 -19, including a pair of walls 10,11 that are internally connected by drop threads 28 that limit the separation between the pair of walls 10,11 when the internal volume is inflated by the quantity of water.
