ABSTRACT:
Device for fixing a rail on a tie, comprising an abutment made of plastic material and a clamp made of steel fixed by a rail screw or a nut. The clamp is provided with an oblong hole which makes it possible to displace the clamp in a direction perpendicular to the rail, in such a way that the clamp can occupy a preparation position, in which the rail can be placed vertically between two abutments, and a fixing position, in which the clamp bears against the flange of the rail. This device makes it possible to pre-equip ties in workshops.
