Products and Services Rockfall Barriers
Certified Rockfall Protection Systems
The rockfall barriers, as outlined by the EOTA – ETAG027 guidelines, are made of one or more identical functional modules placed sequentially, allowing the rockfall barrier to adapt to the necessary length for protection of people and/or infrastructures below. The assembled systems are classified according to the level of kinetic energy which the rockfall barrier is able to absorb, considering both the Service Energy Level (SEL) and the Maximum Energy Level (MEL).
The rockfall barriers which we offer have been certified for MEL levels equal to:
1000 kJ (follow this link for further detail) – Class 3A, residual height > 50% nominal height
2000 kJ (follow this link for further detail) – Class 5A, residual height > 50% nominal height
3000 kJ (follow this link for further information) – Class 6A, residual height > 50% nominal height
2000 kJ (follow this link for further detail) – Class 5A, residual height > 50% nominal height
3000 kJ (follow this link for further information) – Class 6A, residual height > 50% nominal height
Every functional module provides:
- The easy substitution of components, allowing for the replacement of any damaged parts following a rock fall event;
- The rapid construction of the structure and easy on-site installation.
We also offer rockfall barriers without upslope retaining ropes/anchors, an indispensible structure in cases where you want to have space available above the structure, whether it is necessary for maintenance or for passage of motor vehicles.
Components of all rockfall barriers
Rockfall protection systems basically consist of:
- A support structure: assembled in structural steel sections at least HEA 160, connected to the base plate with a unidirectional hinge pin;
- Foundation plates: made from S235JR constructional steel , they differ depending on the terrain, loose soil or solid rock, in which they are installed;
- An interception structure: ring panels that interlock at four points with a maximum diameter of 350 mm made with a fiber of minimum 10.5 mm diameter;
- A breaking system: the various elements dissipate the kinetic energy in work of deformation and friction caused by the wire rope sliding towards the load bearing plate, with the consequent progressive reduction of free fall;
- A connecting structure: made with steel wire ropes of a minimum 20mm diameter for the top braces and 24mm for the connecting wire ropes;
- An anchor structure: made of 1x19 or 1x37 fiber steel spiral wire rope, bent so as to form a shackle of double wire ropes with a ring made from pipes bent into loops at the end.
Based on these principles of modularity, the products developed and sold by Rockfall Defence allow companies to transport and install the products even in difficult areas, guaranteeing simple groundwork at the construction site, with a significant savings of time and resources.
