摘要:
The invention relates to a derailment-preventing device, comprising, on either side, a flanking element (33) which does not rotate with the corresponding roller (13), and which includes at least one inclined flap (49) that is pivotably hinged between a bottom position, in which the bottom portion (51) thereof extends under the head of the rail, and a top position, in which the bottom portion thereof is laterally spaced apart from the rail. The pivot pin (55) of said flap is inclined upward and located in the rear portion of the flap, above the bottom portion (51) in the bottom position. Said flap is subjected to a downward return force that keeps the flap in the bottom position, but allows the pivotal movement thereof into the top position when an upward force greater than the return force is applied to the bottom portion of said flap.

The invention concerns a rail crossing device (1) designed for crossing a first rail (5) embedded in a road surface (4) with a guide rail (21), embedded in the road surface (4). It comprises at least one extensible portion (32) provided in the guide rail (21) and at least one manoeuvring means (33). This manoeuvring means (33) is designed to extend and contract the extensible portion (32) in a lengthwise direction, defining a contracted position in which one end (28) of the guide rail (21) is separated from the first rail (5) to allow a vehicle or any other movable device to travel along this rail, and an extended position in which said end (28) of the guide rail (21) is moved towards the first rail (5) in order to guide a vehicle onto the guide rail (21).

The electric power supply assembly with assisted establishment of electrical contact of the type having a power supply arm (4) supported by a post (5) along the trackway that comes into electrical contact with a longitudinal conducting track (2) borne by the vehicle is characterized in that the arm (4) has at the end a rolling or sliding means which comes into moving contact with an adjacent track (20) running alongside the conducting track (2) at the start of the length of the latter track. This invention applies to the field of electrically powered vehicles that have at least one longitudinal power supply conducting track.
