Page 8: Hazard Notes
RELEASING TENSIONED PARTS Releasing or separating tensioned parts should be avoided wherever possible. If this is necessary, how- ever, please exercise the utmost caution. Page 8/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...
Page 9: Tools For Installing Rockfall Barriers
• At least 2 tension belts • Cable winch hoist, e.g. LUG-ALL ® • Chain hoist or HABEGGER wire rope hoist, min. 1.5 t (15 kN) • Auxiliary ropes Page 9/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...

, where t is the width of the clamping jaws. The loose rope end has to be 3 x e at a minimum. Geobrugg recommends looping up the remaining free section and fixing it directly behind the last wire rope clip on the tightened rope.
Page 11 Wire ropes that have not been damaged can be used again, but the threads and the saddle, in particular, must be inspected for any damage. Page 11/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...
Page 12: Staking-Out In Accordance With The Terrain
The base plate must be positioned in such a way that the bottom support rope bypasses and is not damaged by the edges of the foundation. Page 12/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...

Page 14: Staking-Out Geometry
To ensure that the barrier still functions properly in these cases, you may make several small adjustments to the cross-section or length of nets, ropes, posts, etc. If you inform Geobrugg of these deviations, we can work together to find a adapted solution quickly. Orientation of the foundations and base plates Base plate type 2 can be used on a concrete foundation with two parallel anchors as well as with a 45°...
Page 15 The distance of the upslope anchor rope 236  depends on the possible angle  and must be adjusted and the length of the upslope  anchor rope must be checked.  Page 15/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...
Page 16 With simple terrain conditions and suitable tools, we recommend a support rope separation after approximately 60 – 100 m. In Switzerland, a support rope separation is required after 60 m. In Austria, a support rope separation is recommended after 60 m. Page 16/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...
Page 17 For example in case of a change in direction of 35° the forces are 2.3 times higher than for 15°. Consultation with Geobrugg is recommended Page 17/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...
Page 18 With a change in direction towards the downslope with an angle of 30° - 40° an additional upslope anchor rope is needed in distance d. The maximum change in direction toward the downslope of 40° must not be exceeded. Page 18/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...

Page 23 You can find more information about anchoring the base plate in the anchor data sheet. The forces that may occur in the event of a rockfall event must not be underestimated. Civil engineering and installation work must therefore be carried out by experts. Page 23/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...

Page 37: Additional Solution To The Standard
ROCK FACE CONNENCTION If it is not possible to use the standard staking-out procedure, an option for solid rock can be developed in consultation with Geobrugg AG. This also involves installing towing nets at the edges of the structure. GAP FILLING SOLUTION On steep mountain slopes with mountain torrents, there may be larger gaps between the ground and the lower support rope.
Page 38: Final Inspection
Are the nets connected correctly? Are the end nets correctly fastened to the vertical ropes? Is the sag of the top support rope less than 3% of the distance between the posts? Page 38/41 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland GBE-100A / 06...
