Page 7: 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 7/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13... -
Page 8: Lifespan
If the functional efficiency or load-bearing capacity of the components is reduced as a result of damage or corrosion, such that the minimum required safety factors can no longer be fulfilled, the components must be replaced. Page 8/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13... -
Page 9: Inspections
These should be carried out before the onset of winter or after the end of winter. Digital monitoring devices on the flexible safety structures, such as the GUARD from Geobrugg AG, provide 24/7 access to the most important information about the current condition of the barrier, and any necessary maintenance measures can be reliably defined. -

If the anchor is pulled out of the ground by more than 3 cm, it must be replaced, since under certain circumstances its load-bearing capacity may no longer be sufficient. Page 11/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13... -

Page 15: Use Of Wire Rope Clips
Wire rope clips have to be retightened biannually until the settlement behaviour has finished. In 2016 Geobrugg switched from wire rope clip EN 13411-5 type 1 to type FF-C-450 type 1 class 1. It is important to use the correct installation details. -
Page 16: Type Ff-C-450 Type 1 Class 1 (New Type)
2 x t , 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 17 A visible contusion of the wire ropes positively indicates that the wire rope clips have been tightened to the required tightening torque. Page 17/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13...
- Page 18 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 19: Repairing And Replacing Components
If this is no longer possible, a technically acceptable solution must be agreed with Geo- brugg. The correct geometrical arrangement of the individual components can be found in the product manual.

Page 20: Replacing Ropes
• Release the wire rope clips of the rope and remove them. • Fit the new rope. • Tighten the wire rope clips for the new rope with the required tightening torque. Page 20/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13... -
Page 21: Replacing U-Brakes
• Release the cable pulley device so that the tensile force is transferred to the U-brake rope. • Detach the cable pulley device. Page 21/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13... -
Page 22: Repairing Nets And Meshes
If the mesh loops of a smaller mesh area have been pulled along in sympathy, a correspondingly small mesh can be laid over the damaged area and fastened to the intact mesh loops with wire binders.

Page 23: Replacing Nets And Meshes
Connect the new mesh to the intact adjacent meshes with a TECCO spiral (or with shackles). Connect the eyelets of the two TECCO spirals with a shackle and remove the strain relief. Page 23/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13... -

Page 27: Rocco: Replacing Individual Rings
The easiest way to replace individual rings is by fitting a replacement ring into the net with shackles. Cor- responding prefabricated rings can be obtained via Geobrugg. The new ring is fastened to the adjacent rings with four shackles before the damaged ring is cut out. -
Page 28: Rocco: Replacing A Net Field
Take care to ensure that the correct number of rings is fastened to the right and left of the post, not on the support ropes, but on the U-Ropes. Detailed information can be found in the corresponding product manual. Page 28/33 © Geobrugg Gruppe, CH-8590 Romanshorn, Switzerland Maintenance manual GBE, RXE, ROCCO and ATT / 13... -
