Abstract: A longitudinal element produced with a core made of high-strength fibers and at least one metal casing, preferably steel, surrounding this core. In this way, there is the significant advantage that these high-strength fibers, which are very lightweight in relation to their strength, are protected in a number of ways, namely against humidity, moisture, UV light and other environmental influences. In addition, the metal casing provides the fibers with protection against transverse loads. In this way, all the high-strength properties of the traction or suspension means are maintained over a sustained period.

Abstract: A prestressing cable, in particular for static structures, that includes a longitudinal element and connection elements at the end faces of the longitudinal element. The longitudinal element has stranded wires, the end faces of which are anchored into the connection elements. The prestressing cable includes approximately parallel strands, each of which has stranded wires. The wires are spread apart at their end faces in the funnel-shaped opening of the respective connection element and anchored by a casting process, wherein the frustum-shaped funnel widens away from the strands.

Abstract: Inspection and monitoring system consists of a measuring unit fixedly installed in the cable railway, a storage and transmission unit operatively connected to the latter for the storage and communication of the measurement data, and an assessment unit connected to the latter via Ethernet or some comparable network in order to assess and visualize the measurement data in a remote monitoring station away from the cable railway from which the inspection process is initiated automatically according to a set program. Assessment of the inspection results in the remote monitoring station also takes place automatically by means of a pre-specified program. The station can be in operation around the clock and can also monitor a number of cable railways a long way away at the same time. It works reliably without staff interaction and enables precise management of the cable in view of its optimal life span.

Abstract: The invention relates to a prestressing cable (1), in particular for static structures, said cable being provided with a longitudinal element (1?) and connection elements (2) at the end faces of said element. The longitudinal element (1?) has a plurality of stranded wires, the end faces of which are anchored into the connection elements (2). The prestressing cable (1) is composed of multiple approximately parallel strands (3a, 3b, 3c), each of which comprises multiple stranded wires (7). The wires (7) are spread apart at their end faces in the funnel-shaped opening (5) of the respective connection element (2) and anchored by a casting process, wherein the frustum-shaped funnel widens away from the strands (3a, 3b, 3c). The straight arrangement of multiple strands results in particular in the significant improvement of the properties relating to vibrational loads even with wires of high strength.

Abstract: With a wire rope comprising at least one plastic core (11) and a number of wire strands (15) twisted around the latter a helical groove (20) is respectively produced by machining around the periphery of the plastic core (11) for each wire strand (15). The cross section of these helical grooves (20) is respectively matched to the outside diameter of the wire strands (15). The plastic core (11) is provided with the helical grooves (20) for receiving the wire strands (15) by this machining directly before the wire strands (15) are wound onto said core. By thus forming the wire rope by means of this machining in order to produce helical grooves of the plastic core, optimal guiding of the wire strands in the twisted state is achieved, and so overall there are improvements to the properties of the wire rope.

Abstract: A device for defense and protection from projectiles, especially shaped charge projectiles, is provided with at least one grille-type protective barrier for the protection of an object by deflection, partial release, release and/or damage to the shell projectile. The protective barrier includes a netting forming meshes that are rectangular, triangular, hexagonal, polygonal and/or rhomboid. Such a device is lighter and easier to install in comparison to conventional protective grilles.

Abstract: A cable, which is especially suitable as a suspension cable for cable railways, is described. The cable comprises a core (31) and several outer strands that surround the core and consist, for example, of several wires (32.1 . . . 32.6, 34.1 . . . 34.12). The cable is characterized by an integrated antifreezing device (33.1 . . . 33.6) which can be controlled from one end of the cable, preferably to prevent or specifically remove ice formations on an outer side of the cable. The antifreezing device (33.1 . . . 33.6) is thereby preferably integrated in at least one of the outer strands, however, it can also be integrated in the area of the core (31) of the cable or in inserts that fill spaces between individual wires (32.1 . . . 32.6, 34.1 . . . 34.12) of the cable. As the antifreezing device (33.1 . . . 33.6) is preferably configured as resistance heating, its heat intensity can be accurately adjusted by the flow of the current.

Abstract: A shock absorbing device for a cable under tension, in particular for rockfall, debris flow and avalanche control works, is equipped with an elongate, helical deformation element (1), through which the cable (9) can be looped. Both overlapping end areas (2, 3) of the deformation element (1) are guided through a holding element (10; 30), and the deformation element (1) is plastically deformable when the cable is overloaded, by reducing the helical diameter. The holding element (10; 30) has bevels or roundings (21, 22, 23; 40, 41) at the entry and exit of an opening (31) formed for the overlapping end sections (2, 3) of the deformation element (1). The effect of this is that the reduction of the helical diameter can progress more consistently than before, and also the load-damping curve can be defined better.

Abstract: In order to improve visibility and hence to reduce the risk of accidents, a load-carrying rope, for example a wire rope, is equipped with a number of luminous elements. A luminous element may in this case assume the position of a wire or of a braid, may be integrated in an insert, or may be guided in the spaces between wires or braids and preferably within the theoretical rope circumference. The luminous element may also itself be composed of luminous elements which are twisted together, spiralled, or laid in so as to form braids. For strain relief, the luminous elements may be equipped with a reinforcement in the form of a strand, or with a mesh.

Abstract: A catchment net (1), especially for rockfall blocking, includes a net (2) consisting of elements that engage with each other, and whose two longitudinal sides are each moveably held by a holding rope (3, 4) extending between at least two support bodies (7, 8, 9, 10). The two holding ropes (3, 4) are moveably held by the individual support bodies (7, 8, 9, 10) in their longitudinal direction and tensioned at the side. At least one running rope (37, 38, 39, 40; 47, 48, 49, 50) or suchlike extending alongside the support body on each of the holding ropes (3, 4) preferably within the area of the each support body (7, 8, 9, 10) is affixed with one end on one side and with the other end on the other side to the support body (7, 8, 9, 10). The net (2) is moveably held within the support body area by the running ropes (37, 38, 39, 40; 47, 48, 49, 50). The catchment net (1) therefore guarantees an optimal load distribution as well as a more favorable flow of energy through the net.

For strain relief, the luminous elements may be equipped with a reinforcement in the form of a strand, or with a mesh. The luminous element is intended to be connected to a source. In the state when it is fed, the luminous element is actively luminous. Owing to the improved visibility, rope lights may be used not only for a safety function but also for an aesthetic appearance.

Abstract: A catchment net for rockfall catchment systems or the like has a net (12, 33) and support elements (16, 17, 18, 19). The net (12, 33) is retained on the outside, on at least two mutually-opposing sides, by least one peripheral cable (14, 15, 41, 42) in each case, and/or by a tensioning cable (22). Additional connection elements (25, 46), which connect the net (12, 33) to the support elements at its outside, make it possible for the energy incurred in the event of a rock (23, 31) or the like falling into the net to be absorbed to the maximum. The connection elements can, however, also be secured additionally or only in the interior of the net.

Abstract: A wire netting, preferably used as a gravel screen or for protecting a soil surface layer is woven from corrosion-resistant wires and either fitted on the soil surface or secured in an almost upright position on a slope or something similar. The wires in the wire netting are manufactured from heavy-duty steel, which has a nominal strength in the region of 1000 to 2200 N/mm2 and steel wire may be used for this for stranded wires or spring steel wire. The wire netting is manufactured from rectangular, diagonal netting and it has a three-dimensional, mattress-like structure.

Abstract: To reduce elongation of a stranded wire rope or cable (1), particularly when running over sheaves, or pulleys, and decrease vibration as well as operating noise while increasing operating speed, insert elements (4) are placed between adjacent rope elements (2). The insert elements, in cross-section, have an intermediate portion part (7) with oppositely positioned concave recesses (9), a head portion (6) which can be widened to the circumferential diameter of the rope or cable (1) and a widened base portion (8). The base portions (8) are not interconnected. The insert ribbons or tapes are preferably formed along their length with slits (11) extending from the head portion (6) to about the middle of the ribbon or tape to allow for bending of the rope, and the inserts about circular pulleys.

Abstract: A retaining net is made of wire rings which are interlooped when producing at least some of the rings while other rings that participate in the interlooping are prefabricated. Such nets are used for protection against falling rocks, avalanches, and mud slides. The interlooping rings are formed by feeding a wire (22) through a bending tool (15) to form several turns that interloop with at least two prefabricated rings (20A, 20B) that are held by suspender members (31) so that the rings (20 being formed extend crosswise to the prefabricated rings. When the formation of a first row of interlooped rings is completed, that row is interlooped with a second row and so forth. The interlooped ring structure provides a simple, cost effective construction method for strong retaining nets.

Abstract: A steel cable eyelet construction for a looped steel cable end is protected against corrosion by a tubular member of synthetic material that extends all the way around the loop and partially into the ground when the steel cable end is formed as an anchor that is cemented into the ground. The synthetic material tubular member in turn is protected against mechanical wear and tear by a tubular metal jacket such as a stainless steel jacket. This construction is especially suitable for anchors that are used to secure protection nettings against falling rocks and avalanches. Providing the corrosion protection and the mechanical wear and tear resistance by different elements assures a prolonged serviceability of such steel cable eyelets forming anchors cemented into the ground.

Abstract: To permit absorption of sudden impacts or shock overloads, or gradual overloads, on a cable stretched to retain stones, rocks or snow masses, for example in road or railway cuts, a tube is bent to form an open loop, the end portions of which are held together by a clamp so that the end portions are frictionally engaged against each other, and the cable is threaded through the tube. Upon overload, the tube can plastically deform, thereby reducing the diameter of the loop or ring formed thereby, and accept overloads without overloading or unduly stressing the cable.

Abstract: To provide a predetermined pre-set twist or rotation about an angle corresponding at least approximately through the spiraling angle of strands (8) wrapped about a core wire or strand (48), the individual surrounding strands are passed through directionally orienting dies (20, 28) which may receive circular strands and impart an approximately truncated wedge-shape thereto, or directly receive pre-shaped strands. The orienting dies are angularly adjustable in a holder (26) which, in turn, is rotatable about an axis transverse to the axis of the die opening, all the dies being secured to a carrier plate which is axially adjustable with respect to the stranding die (7) of the apparatus.
