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

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.
