TROLLEY FOR A SLIDABLE CANTILEVER GATE AND PROCESS FOR ITS MANUFACTURE

Trolley for a slidable cantilever gate comprising two L-shaped plates, each provided with a load-bearing wall and a base wall which is extended without interruption from the load-bearing wall by means of a substantially orthogonal fold. The load-bearing walls are rigidly connected by means of screws or rivets with the two base walls oriented in opposite directions so as to form a support base on ground. Each load-bearing wall is provided with two first through openings aligned with respective corresponding first openings of the other load-bearing wall so to jointly define two first seats adapted to house first rotatable support means for two pairs of support wheels; and with a second through opening aligned with that corresponding on the other load-bearing wall so to jointly define a second seat for receiving a guide wheel, rotatably supported by second rotatably support means. The load-bearing walls, moreover, are each provided with a first shape with concavity facing that of the other load-bearing wall in order to jointly define a first housing adapted to receive a fixing screw of the pin of the guide wheel, and a second shape with concavity facing that of the other load-bearing wall in order to jointly define a second housing, which communicates with a vertical guide defined in one of the first seats, and houses adjustment means operating on a slide which bears, pivoted, a pair of adjustable wheels, in order to adjust its vertical height. Carro para cancela corredera en voladizo que comprende dos planchas moldeadas en forma de L, cada una dotada de pared portante y de una pared de base que se extiende sin solución de continuidad desde la pared portante mediante un pliegue esencialmente ortogonal. Las paredes portantes están conectadas entre sí rígidamente mediante tornillos o remaches con las dos paredes de base orientadas hacia direcciones opuestas para formar una base en el suelo. Cada pared portante está provista de dos primeras aperturas de paso alineadas con respectivas homólogas primeras aperturas de la otra pared portante para definir conjuntamente dos primeros asientos aptos para acoger primeros medios de soporte giratorio para dos parejas de ruedas de soporte; y de una segunda apertura de paso alineada con la homóloga de la otra pared portante para definir conjuntamente un segundo asiento para recibir una rueda de guía, soportada de modo giratorio por segundos medios de soporte giratorio. Además, las paredes portantes están provistas cada una d
