On September 13th, 2023, the 2000KJ OST rockfall barrier successfully intercepted the rockfall on 131 County Road in Nantou, Taiwan, with a volume of 20m³ and nearly 48T. Before 2017, frequent rockfall affected the area and caused a number of deaths and damages to the traffic. Based on the terrain, OST set up a 2000KJ easy maintenance barrier which enables the easy restoration of the protection system after cleaning up the blocks and replacing the energy dissipators. Since then, a number of rockfalls have occurred, which were all successfully intercepted. Thanks to the rockfall barriers, these essential traffic routes in Nantou are always being rockfall-proof.
