VR has been dealing with amphibian protection for many years and has developed a very simple, technically mature and very effective guiding system: The system AmphibianGuard. The AmphibianGuard guiding profile is made of 2.5 mm thick steel plates, has a length of 4,000 mm, a width of 200 mm and a height of 400 mm. Our system thus meets the requirements of the MAmS 2000. The double overhang, with a width of 70 mm and an additional 90-degree bevel of 20 mm below makes it impossible to climb over the guiding profile. The walking chamber with an additional bevel of 50 mm is integrated into the soil, so that it will prevent the amphibians from underrunning the system. The AmphibianGuard guiding profile can be adapted to the local topography both horizontally and vertically. Miter cuts and the flexible plate angle of 10° - 90° guarantee a joint-free installation even under hardest conditions.
