Page 8: Hazard Warnings
REMOVAL OF PARTS UNDER TENSION The removal or separation of components under tension is to be avoided whenever possible. Should such work be necessary, however, the utmost caution must be taken. Page 8/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 9: Tools For Installing Rockfall Barriers
• Rope clamp – small 8-16 mm / large 14-26 mm (at least 2) • At least 2 tension belts • Cable winch hoist, e.g. LUG-ALL ® • Chain hoist or come-along, at least 1.5 tons (15 kN) • Auxiliary ropes Page 9/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 10: Using The Wire Rope Clips
, 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 Undamaged wire rope clips could be reused. Especially the threads and clamping jaw have to be checked. Wire rope clips always have to be installed and used with the required tensioning torque. Page 11/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 12: Staking Out Subject To Terrain
The baseplate must be positioned in such a way that the lower support rope is routed past the edges of the foun- dations without being damaged by them. Page 12/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 13 > 0.50m > 1.00m > 1.50m Net must be adjusted If the height difference is greater than in Tab.2 you must contact Geobrugg to enable the correct length of nets to be determined. Page 13/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland...

Informing Geobrugg about the deviations enables you to work together to quickly find a solution that is adapted to your requirements.

Page 17 In the case of a change in direction towards the valley of more than 30°, two additional retaining ropes (D) are mounted on the post. The change in direction towards the valley must not exceed 40°. Page 17/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 18: Rope Anchor - Installation
The anchor holes are drilled in the pulling direction, with a minimum angle of > 15° to the horizontal. The anchors must be inserted into the holes up to the marking and mortared in a horizontal position of the anchor head: Page 18/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...

Page 20 Further information about the anchoring of the base plate can be found on the anchor forces date sheet. The forces that occur during a rockfall event are not to be underestimated. The civil engineering and in- stallation work must therefore be carried out by professionals. Page 20/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 21: Preparation Of The Nets And Posts
8 meshes on top and bottom of the SPIDER net are left free. The support ropes are only guided through the bundled and red marked meshes. Later each second free mesh will be attached to the support ropes with round clips. Page 21/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 22 The net bundle is placed on the mounting bracket and securely fastened with bands 204. It has to be taken into account that the right number of meshes next to the posts are left free (see page 31/32). Page 22/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 23 X: With larger height differences, it’s easier to pull down the panels from higher to the lower post. With appropriate ordering details Geobrugg provides the panel on the wished side of the post. Page 23/43 ©...
Page 24: Crane Or Helicopter Installation
Fasten the mesh bundle using strips 204 so that it cannot fly away Use the centre 7/8" shackle 205 on the top of the post to lift the posts. Never use the rungs 203 Page 24/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 25: Installing The Superstructure
• Install the U-Brake for the bottom support rope on the anchors. Fasten the bottom support rope to the base plates of the posts and tension the bottom support rope. The support ropes are guided through the relevant SPIDER meshes. Page 25/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
Page 26 29. The TECCO rope is guided through the U-profile of the TECCO panel. • Install the vertical rope to the U-Brake. • Loose the U-profiles and open the panels. Connect the panels vertically. Page 26/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...

Page 37 A support rope separation always contains an intermediate rope suspension. In the case of an intermediate anchor rope without support rope separation, the two intermediate suspen- sion ropes at the centre hole are fastened with a 7/8" shackle.

Page 39: Additional Solution 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.
Page 40: 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 40/43 © Geobrugg AG, CH-8590 Romanshorn, Switzerland GBE-3000A / 16...
