CA 2360183

A bottom anchor assembly (10) for a substantially vertically-oriented elongate safety line (70) comprises safety line gripping means (20), safety line tensioning means (80) and a bracket (50). The gripping means (20) includes a manually adjustable clamp (20) and the tensioning means (80) includes a hollow shaft (40) through which the safety line (70) passes. The hollow shaft (40) is externally screw-threaded and carries the load-setting means (80) on its screw-threaded portion (41). The load-setting means (80) is adapted to bear against the underside of the bracket (50) for adjusting the safety line tension to a predetermined value. The bracket (50) may have open jaws (51, 52) for receiving the hollow shaft (40) when it is already installed on the safety line (70). The ends of the open jaws (51, 52) may be provided with down-turned portions (53, 54) for preventing accidental removal of the load-setting means (80) from between the jaws (51, 52) when the system is adjusted to its predetermined tension.

L'invention concerne un ensemble (10) de fixation inférieur pour câble (70) de sécurité de forme allongée sensiblement vertical. Ledit ensemble comprend des moyens (20) de préhension du câble de sécurité, des moyens (80) de tension du câble de sécurité et un support (50). Les moyens (20) de préhension comprennent une pince (20) à réglage manuel, et les moyens (80) de tension comprennent un axe creux (40) dans laquelle passe le câble (70) de sécurité. L'axe creux (40) à filetage externe est pourvu de moyens (80) de réglage de la charge sur sa partie filetée (41). Les moyens (80) de réglage de la charge sont conçus pour reposer sur la surface inférieure du support (50), ce qui permet d'ajuster la tension du câble de sécurité à une valeur prédéfinie. Le support (50) peut comporter des mâchoires (51, 52) ouvertes destinées à recevoir l'axe creux (40) une fois installé sur le câble (70) de sécurité. Les extrémités des mâchoires (51, 52) ouvertes peuvent comporter des parties (53, 54) courbées vers le bas, afin d'éviter toute sortie accidentelle des moyens (80) de réglage de charge des mâchoires (51, 52) lorsque le système est ajusté à sa tension prédéfinie.
