    Ropes are under tension. Ensure that no one is standing in the danger zone while the ropes are being in- stalled and pre-tensioned. RELEASING PARTS UNDER TENSION Avoid releasing or disconnecting components under tension wherever possible. If, however, this is nec- essary, please exercise the extreme caution.

  • Page 43: Special Solutions In Addition To The Standard

    If there is insufficient space for staking out the lateral anchors as standard, you can consult with Geobrugg AG to develop a strut solution. ROCK CONNECTION If standard stake-out is not possible, you can consult with Geobrugg AG to develop a rock connection var- iant. GULLY SOLUTION Larger openings between the ground and the lower support rope may form on steep mountain slopes with mountain torrents.
