Area ofApplication:TRUMER rockfall catchment fences were developed to protectinfrastructure, utilities, buildings and lives from falling debris.Typical catchment fences are installed in run-out or depositionzones, close to the elements at risk that they protect. The TSC-100-ZD used for projects of high risk (Consequence Class in ENis1990:2003 ) as per ONR 24810 .[1] [2]

Material:TRUMER uses steel components and steel wire ropes made fromhigh quality materials, following a stringent quality assuranceprogram. The structure was tested as per ETAG 27 and[3]manufactured in accordance with the European TechnicalApproval ETA-1 /0 6. TRUMER Schutzbauten GmbH is ISO2 159001:2008 certified.

Installation:The TSC- -ZD has been designed with as few components as100possible to simplify installation and reduce maintenance. Inaddition, the systems can be installed by hand, with heavymachinery or with the use of a helicopter. Foundation design andconstruction is dependant on site conditions and are theresponsibility of the project engineer.

Advantages:This system has been tested with no failures of primarycomponents even though certification allows such failures. Assuch, the TSC- -ZD rockfall catchment fence carries the100highest safety ratings.

Typical Cross Section General Layout andAnchorage:The suggested layout for therockfall catchment fence followsthe constructive rules of the ONR24810. In general, post spacing iskept between 8 - 12 m. Postsshould be positioned to create thegreatest capture shadow withregards to vertical as well as lateralspread of falling debris, with thefence roughly perpendicular to thefall line. Avoid the placement ofposts in areas that increase thechance of a direct post impact.

Anchor layout should follow thegeometry provided in theinstallation manual with the anchororiented as close as possible to thedirection of the anticipated ropeforces. It is acknowledged that dueto site characteristics deviationsfrom the ideal are unavoidable. Inthis case, the project engineershould use their best judg ment toefind a suitable location andorientation.

* Actual anchorage to be determined by a qualified engineer in accordance with local regulations. Herein, the factors ofsafety were applied according to the ONR 24810 guidelines. If multiple ropes are led to one anchor, it is recommendedthat characteristic force values be added in a scalar manner according to ONR 24810.
