Special architecture mesh for sports stadiums and parking garages as building 8'000 kJ Rockfall drapes/rockfall netting TECCO® and SPIDER® Hybrid (attenuator) rockfall protection. a combination of rockfall protection drapes and flexible rockfall barriers . such as facades and roofs made from glass. Geobrugg Rope Architecture becomes Fatzer Structural Ropes Steel ropes and accessories for architectural requirements. sports stadiums and bridge suspension systems were handed over to our sister company Fatzer AG effective January 1st 2012. Rockfall protection for impact energies from 100 kJ to 8'000 kJ Geobrugg rockfall protection mesh systems (catch fences and rockfall drapery/rockfall netting) made from high-tensile steel wire consist of the following product groups to match different rockfall problems: Rockfall catch fences TXI with BAFU approval for impact energies up to 100 kJ without retaining ropes Rockfall barriers RXI and AXI series with BAFU approval for impact energies 250 kJ to 5'000 kJ Rockfall protection barriers with ETAG approval GBE series for impact energies 100 kJ . Their diameter range extends from approximately 6 mm to approximately 130 mm. Geobrugg AG is a company of the BRUGG Group. Ball catch fence for sports stadiums.facades. stairwells and fall protection. Rollaway fence system for sports stadiums and major events. They are producing open and full-locked steel ropes in the group’s own rope-making factories. .RXI/AXI rockfall protection barriers and rockfall meshes 250 – 5000 kJ with BAFU approval RXI rockfall protection barriers and rockfall meshes stop rocks which even overwhelm concrete galleries We supply our RXI rockfall protection barriers and catch fences approved according to the guidelines of the Swiss Federal Office for the Environment (BAFU) for absorption capacities of 250 kJ (low energy). 500 kJ. AXI for 250 and 500 kJ: reinforced posts replace retaining ropes We developed the AXI rock fall barriers for protective structures adjacent to (service) roads: they have reinforced posts which do away with the need for retaining ropes. tree falls and snowslides. 1500 kJ and 2000 kJ also for 3000 kJ and 5000 kJ (high energy). The components Ground plates with linked post fixing Spiral rope anchors or self-drilling anchors with Geobrugg FLEX head . ROCCO®ring net and RUNTOP®running rope as central elements In the case of an event the energy is first dissipated through the plastic deformation of the ring bundle. 1000 kJ. The rigid AXI systems are also suitable for supporting walls. RUNTOP® running ropes allow the ring net which is fixed to shackles to slide in a matter of split seconds to the place they are most needed (curtain effect). This reduces the stress on the anchors. They are characterized by large residual heights in the impact field. no deflection with maximum event and the ability to maintain functional serviceability with combined stresses such as multiple hits. existing concrete structures or compacted rockfaces to which they can be simply mounted and anchored. 500 kJ. we verified a residual useful height of over 50% of the original construction height. The European Technical Approval (ETA) was issued by a recognized licensing authority. where they are drawn over the supporting rope like a drape. The high-tensile TECCO® or the SPIDER® spiral rope net can be delivered to the site preassembled to the posts. guided by brake rings These rockfall protection barriers satisfy the conditions of the guidelines of the Swiss Federal Office for the Environment BAFU. 1000 kJ. This allows the product to carry the CE mark which in a few years will become obligatory in all European countries. Mounting: Amazingly quick and simple The mutually adapted components are quick and simple to install. Supporting and retaining ropes. 3000 kJ. . GBE barriers satisfy the most stringent requirements of ETAG 027 category A Our GBE rockfall protection barriers and catch fences have a verified residual useful height corresponding to the highest category A of ETAG 27: After the test at 100% of the nominal energy.8000 kJ with ETAG approval The new GBE rockfall protection barriers and catch fences are supplied for impact energies of 100 kJ. 2000 kJ. GBE rockfall protection barriers and catch fences for 100 . 5000 kJ and 8000 kJ and have been successfully tested and approved under vertical fall conditions according to the guideline ETAG 27. 11/0459 and 12/0213. 09/0369. 09/0262.eu > valid ETAs > criteria: ETA number > 09/0085.For further information visit www. .eota. 10/0084. 11/0034. 11/0305.
