Abstract: A damper device comprises a cylinder, a piston bearing on one side of the cylinder, a piston rod displaceably received by the piston bearing, and a bottom unit on another side of the cylinder. The cylinder, the piston bearing and the bottom unit form a closed chamber that is filled with a compressible liquid. The piston rod subdivides the chamber into first and second chamber halves between which the liquid can be displaced if the piston rod is displaced relative to the cylinder. Furthermore, the closed chamber provides for a variable volume so as to compensate temperature-induced pressure fluctuations inside the closed chamber.

Abstract: A hanger assembly for mounting an enclosure on an elongate support includes a body, first and second arms, and first and second attachment devices. The body is configured to be secured to the enclosure. The first and second arms each have opposed upper and lower ends. The lower ends are each pivotally secured to the body. The first and second attachment devices are located on the upper ends of the first and second arms, respectively, and are configured to secure the first and second arms, respectively, to the elongate support. The first and second arms can be pivoted about their lower ends to selectively adjust a spacing between the body and the elongate support to thereby selectively adjust a distance between the enclosure and the elongate support.

Abstract: A safety monitoring system for a catenary system that includes an overhead wire, a support pole and a counterweight attached to the end of the overhead wire and suspended by the support pole. The catenary safety monitoring system includes a temperature sensor for detecting an ambient temperature, a position sensor for detecting a position of the counterweight and an electronic controller. The electronic controller compares a detected position of the counterweight with a predicted position determined by the electronic controller using an ambient temperature from the temperature sensor. A message transmitter provides a warning to a user if the detected position of the counterweight is not within a predetermined percentage of the predicted position.

Abstract: An overhead electrification plant for railway lines, or similar, comprises at least one electric wire (9), the so-called contact wire, to power an engine, extending in a predetermined position along the railway line, and being held up by a plurality of suspension elements (3) arranged at predetermined intervals.

Abstract: In an overhead electric traction system a simple and inexpensive mid-point anchor comprises a mast and, mounted on the upper part of the mast, a cantilever structure comprising a pair of rigid elongate members which lie in a common plane and extended transversely with respect to and lie spaced apart in a direction lengthwise of the track, and which at their ends nearer the track are connected to the mast by a third transversely extending elongate member inclined at an acute angle to the common plane. The ends of the members remote from the track are connected to opposite ends of a rigid bar which extends lengthwise of the track, which is pivotally connected to the mast about a vertical axis and which, at each of its end portions, is connected to the mast by a flexible tie. In the event of an unbalanced load on the catenary, pivotal movement of the cantilever structure about the vertical axis is prevented by one of the flexible ties and the out of balance load is transferred to the mast as a torsional load.

Abstract: To prevent longitudinal displacement of the support or catenary cable and the load carrying, tensioned cable of the suspension system, the spacers or hangers between the catenary or support cable and the carrier cable, as well as the suspension and tension of these cables, are so arranged that, in side view, the two cables touch each other at the midpoint between the pylon to provide for equalization of tension in the cables. At that position, a tension or force equalization plate is clamped to both the support cable as well as to the carrier cable, thereby preventing relative longitudinal displacement of the cables with respect to each other.

Abstract: This invention relates to an arrangement for suspending lighting fittings and the like along or at traffic-routes and the like, comprising lines carried by standards and intended to carry or support the lighting fittings. The novelty lies in that the standards and the lines form two separate systems, wherein the line system is continuous along the traffic-route and releasably connected to the standard system so that the line system substantially remains in its elevated position even if part of the standard system is removed on e.g. a standard being struck by a vehicle.

The guyed masts of each support position and the guy wires in the rigging field are tied together in an approximately horizontal plane by catenary-arranged insulators. The conductor cables are suspended from the network thus formed.
