Abstract: A system of the invention includes at least one barrier layer, a plurality of rockfall attenuators and two primary anchor points to anchor opposite lateral sides of the barrier layer. The attenuators are secured to an upper portion of the barrier layer. The attenuators create a gap between the surfaces of the slope upon which the barrier layer is installed. The attenuators are attached to the barrier mesh by a cable routed through a clevis/eyelet on each of the attenuators. Opposite ends of the cable are secured to the sloping surface by the two primary anchor points. The attenuators are free floating members that are not attached to the sloping surface. The invention also comprises attenuators as a sub-combination and a method of installing the system. One embodiment of an attenuator includes interconnected structural members resembling a closed-shaped frame. Another embodiment includes a covering placed over the structural members.

Abstract: Net as a securing or safety net for securing rocks or rock slopes, and against rock falls, landslides or similar natural hazards, wherein said net contains filament yarns from the group of multi- and/or monofilament yarns that are combined in a knot-free manner. In this net, in each case two material strands join at the mesh intersection points, wherein (a) each material strand (A; B) consists of at least two, preferably up to six, individual strands (A1, A2 and B1, B2), and (b) at least one individual strand (A1 B1) of each material strand (A or B) passes through an intersection point without changing direction, (c) while at least one individual strand (A2 or B2) of each material strand (A or B) is deflected in the region of this intersection point and is combined with an individual strand (B1 or A1) of the other material strand (B or A) that passes through an intersection point without changing direction.

Abstract: The application relates to a brake element (10) for absorbing kinetic energy in a catch device, in particular for rock fall, mudslides, earth flows, landslides or tree fall. The brake element comprises a basic body (12) having a first (14) and a second (16) fastening point, wherein a tension element can be arranged at each of the first and second fastening points (14, 16) in such a way that a tensile force acting on the brake element (10) between the fastening points (14, 16) can be applied by means of the tension elements and wherein the first and the second fastening points (14, 16) have a distance (A) from one another along the tensile force.

Abstract: A method for producing a safety net, to a safety net, and to the use of such a safety net for protection from avalanches, falling rock or timber, mudslides, earth flows, or for slope protection. In the inventive method, firstly at least a first net element and at least a second net element are individually produced, self-contained, from respectively at least one rope, and are arranged parallel to each other and at a distance apart in a longitudinal direction of the safety net to be formed. Then the two net elements are connected to each other with the aid of at least one connecting rope, wherein the connecting rope is guided between the first and the second net element such that a self-contained connecting net element is obtained.
