Vertical rockfall protection fence "Loop Fence"
Vertical rockfall protection fence "Loop Fence"
A vertical rockfall protection fence with a simple and rational structure to prevent falling rocks onto the road.
The "Loop Fence" is a vertical rockfall protection fence primarily installed along roads to prevent rockfall damage. It can withstand rockfall energy of up to 1506 kJ, making it effective for relatively large-scale rockfall countermeasures. By wrapping wire ropes in a loop between the posts, it reduces the deformation during rockfall capture. Its minimal protrusion towards the road allows for installation close to the roadside. ■ Catches rockfalls on roadsides and slopes ■ Supports rockfall energy up to 1506 kJ ■ Effective for large-scale rockfall countermeasures Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: SK-020001-V *For more details, please download the PDF or feel free to contact us.

basic information
The loop fence consists of posts, wire mesh, wire ropes, and cushioning devices. The foundation is a pile foundation structure integrated with the posts. The wire rope wrapped in a loop between the posts slips within the cushioning device, efficiently absorbing falling rock energy. *For inquiries or questions regarding products and technology, please feel free to contact us.*

"Suppressing deformation during rockfall capture" By wrapping the wire rope between the supports in a loop, we have achieved a reduction in deformation during rockfall capture. Since the protrusion towards the road is minimal, installation near the roadside is possible.
