An installation device for tension clamps for attaching a rail to a railroad tie or another rail substructure, a method for attaching at least two tension clamps in their installation position by such an installation device, and a system made of an installation device with a drive device connected to it are disclosed.

Gripping mechanism for spindle-screw clipping machine

A rail-mounting assembly (S) for fastening a rail () to a fixed substrate () with an intermediate construction () between the rail () and the fixed substrate () that operatively connects the rail () to the fixed substrate () in an elastic manner, and the intermediate construction () comprises only a elastic intermediate layer element () that has a variable elasticity distribution across its cross-section () in the direction (A) of its longitudinal extension () and/or in the direction (B) transverse to its longitudinal extension ().

Rail fastening system

The invention relates to a rail attachment system () for attaching a rail () to a concrete support slab () or a concrete sleeper () or to a steel structure comprising an intermediate plate (), a rail attachment plate () with angle guide plates () arranged thereon, at least two first tensioning clamps () for clamping the rail foot () to the rail attachment plate () as well as screws () and/or ankle bolts () and at least two second tensioning clamps for screwing the rail attachment system () to the underlying surface, characterized in that an elastic intermediate layer () is arranged between the rail () and the rail attachment plate (), and the intermediate plate () is composed of a highly elastic material and/or comprises a steel plate (), at least two second tensioning clamps () for clamping the rail attachment plate () to the substructure, preferably via the intermediate plate (), wherein the first and second tensioning clamps () are embodied in a highly elastic fashion with a high tensioning force, are provided, and at least one upper sliding plate () is arranged between the rail foot () and a first tensioning clamp (), and at least one lower sliding plate () is arranged between the rail foot () and the elastic intermediate layer () and is attached by means of a steel support () in the case of a steel substructure.

Rail attachment system for junction areas

Rail-fastening system for the non-positive resilient fastening of a rail () on a sleeper () of a railway track installation, comprising at least one angle guide plate (), which can be fixed to the sleeper () with at least one screw (), and at least one clamp (), characterized in that the bending radii of the clamp arms () of the clamp () preferably lie in the range from 18-70 mm, wherein the ratio of mutually adjacent bending radii within each clamping arm is &#x2266;1.9 and the ratio of the greatest to the smallest bending radius thereof is &#x2266;3.8, and in that the ratio of weight to width of the angle guide plate is &#x3c;1.3 g/mm, preferably about 1.25 g/mm.

Rail-fastening system

A system for fastening a rail to a substrate has an anchor in the substrate, a fastener having a shank secured in the anchor and a head above the substrate, an angle guide plate vertically traversed by the shank, an annular part between the head of the fastener and the guide plate, and a spring clip engaged between the head and the part and shiftable transversely of the rail and of the shank between a preinstallation position horizontally offset from and not engaging the rail and a final installation position bearing vertically downward on the rail. A seal ring engages in both the preinstallation position and the final installation position around the shank and compressed between the part, the angle plate, and the shank so as to prevent water from traveling down the shank into the anchor.

The invention relates to a plastic screw plug () for attaching a rail to a sleeper, in particular concrete sleeper, having an essentially cylindrical plug body which has at the head end a stem region () which preferably adjoins a plug crown () toward the bottom, and in the continuation of which stem region () has an outer thread () with which it can be turned out of or into the sleeper, and is provided with an inner thread () underneath the stem region () in order to receive a sleeper screw. The intention is to improve such a plastic screw plug, in particular, with regard to its operating properties such as uniform application of force into the sleeper, simpler mounting and replaceability, reduction of the risk of fracturing, and additionally to permit it to be used in a variable way. For this purpose, the stem region () has on the inside, in the junction with the inner thread (), a shoulder () which reduces the internal diameter over part of the length of the stem region () and extends in a spiral shape over at least part of the circumference.

Plastic screw anchor for securing a rail to a railroad tie

In the case of a hollow sleeper () for adjusting devices of switch blades of railway points, movable common crossings or cable crossings in any desired sections of track and points, formed as an upwardly open hollow sleeper profile with a planar sleeper underside (), for fitting in a track skeleton, wherein the cross-sectional width and height are made to match a normal concrete, wooden or steel sleeper, the positional stability on ballast can be improved if the sleeper underside () of the hollow sleeper () is formed with at least one sunken, downwardly open chamber ().
