Abstract

The present invention relates to a sliding device for railway points which is associated with a rail of a track in the vicinity of a set of points in which a stock rail (4) and a tongue (3) co-operate and which is provided with a support structure (7) on which at least one rotary travel element (8) able to support the tongue (3) in an inactive position (6) is mounted, and with fixing means (9) for fastening the sliding device onto the railway track. The support structure (7) is mounted on top of a slide shoe (2), with respect to which it has a matching box-shaped form having two side flanks (11) on each of which at least one spindle (16) carrying one or more rotary travel elements (8) is mounted. <IMAGE>
