Description

Member of rail fixing component

The present invention is directed to a member of a rail securing assembly.

In the documents of WO 93/12294, WO 93/12295 and WO 93/12296, the Applicant discloses a railway rail fixing system. In this railroad rail fastening system, the rail fasteners are driven laterally onto the rails and can be held in the "pre-assembly" or "parked" position on the fasteners. In the anchoring device (shoulder), the toe of the fastener is not pressed against the rail in this "pre-assembled" or "pause" position. In this way, the fasteners held in the pre-assembled position can be preloaded on the railway sleeper in the factory. When the sleepers are transported to the site, once the rails are in place, only the rails will be in place. The fasteners are driven onto the rails. In addition, when rail maintenance is required in the future, the fasteners can also be driven away from the rails and returned to the pre-assembled position. Such fasteners are sometimes referred to as "on/off" fasteners. This type of fastening system has proven to be very successful, but the applicant wants to make improvements in terms of manufacturing and use.
