Abstract: A lateral extension (1), for road and rail vehicles, comprising a multitude of individual shafts (5) assembled so as to pivot freely, at each of their extremities, firstly, with regard to the interior extremity secured to the vehicle, on a longitudinal structure (11) that is fixed in relation to the load-carrying platform and, secondly, as regards the exterior extremity, on an edge and connecting rigid longitudinal member (10). The shafts bear, over a portion of their length, on an adjacent flat support surface (13) that is fixed in relation to the load-carrying platform, and are cantilevered towards the exterior over the remainder of their length. The extension can be moved to a deployed position, so that the supporting surface (14) provides a passageway, and, a retracted position of lesser width, and incorporates a railing. A changeover from one position to the other is accomplished by pivoting in a horizontal plane.

Abstract: A junction between successive flat pre-fabricated elements which comprises an elastic transverse insert (9), an approaching mechanism (10) in the form of tie beams (23) and tensioning mechanisms (19). The flat pre-fabricated elements (2) to be assembled each have a transverse channel (3) adapted so as to receive the insert along the end transverse edges (4, 5) thereof, which must face each other after assembly on the ground, and conduits (7) of the tie beams. Each pre-fabricated element is successively arranged, one after the other, and the transverse insert is introduced into the transverse housing (6) formed by transverse channels facing each other. The tie beams are introduced into the conduits, the ends thereof projecting outside the pre-fabricated elements. The tie beams are then tensioned by a tensioning mechanism, at each of the ends thereof, in order to immobilize the flat pre-fabricated elements and thereby connected by the tie beams.

Abstract: A prefabricated module (1) to be used in constructing a track for an urban transport vehicle. The module comprises an integral carrier structure (2) made of concrete and comprising two side sills (4) having an upper surface (5), used as a driving pathway for the vehicle wheels, and connecting crossbars (8) which connect and retain the sills substantially parallel to each other. The lower surfaces (6, 39) of the sills and crossbars are ground-bearing surfaces. A guiding rail section (3), mounted on the carrier structure, is preferably symmetrical, has an I section and a lower portion coated with a liner material (13). The modules, whether rectilinear or curved, are to be placed on an existing road layout or in a trench with a compacted bottom, and are connected one after the other to form the driving track.

Abstract: The repeating transverse support is either a one-branch or a two-branch (15, 16) sleeper which is pressed against the bed plate (8) by elements which secure the directional guide rail (2). The terminal ends of this sleeper, which are in the form of mounting plates (23, 24), each support an electrical power supply lateral profile (33, 34) by way of an electrical insulator (27, 28) and an adjustment member. This repeating transverse support is of interest to the manufacturers of tracks for electrically powered guided road vehicles.

Abstract: The maneuvering device comprises two hydraulic motors (14, 15), each attached to the base of each screw (4, 5) integrated into each post (2, 3) of a pair of posts. The hydraulic motors (14, 15) are supplied in series by a single course of pressurized fluid and each shunted through a bypass comprising a hydraulic shunt which opens either automatically or is regulated to open completely, partially or progressively. This invention is of particular interest to auto body manufacturers for use on road trailers for carrying vehicles.
