Rockfall protection "LDB-500" that can be installed in areas with little distance from the preservation target.

A rockfall protection fence with reinforced posts that has a small deformation amount during rockfall impact. The shock absorption device is easy to replace and has excellent maintenance characteristics.

This is a rockfall protection system with reinforced posts that can absorb rockfall energy up to 500 kJ and has a small fence deformation during rockfall impacts. The fence deformation is less than 2.0 m (1.34 m in full-scale tests), making it most effective in narrow locations such as alongside roads and railway tracks. 【Applications】 ● Rockfall measures in narrow installation areas ● Rockfall measures alongside roads and railway tracks 【Features】 ● The fence deformation is less than 2.0 m, so it does not encroach on construction limits. ● By rigidly connecting the upper chord and posts, low deformation is achieved. ● The performance of the protective fence has been verified through full-scale testing. ● Rockfall energy is absorbed by the balanced arrangement of impact-absorbing components (U-brakes) utilizing the bending deformation of steel, and high toughness and high strength posts made by combining H-beams and steel pipes. ● Each span has an independent structure, allowing for maintenance and repairs within a limited area. ● It can be installed directly on retaining walls or on the ground.
