Patent ID: 7980570

Claim:
Trolley for a slidable cantilever gate provided with a support framework having a predominant extension along an advancing direction and bearing fixed, on its lower part and along said advancing direction, a hollow rail for the guide of said gate; said gate comprising: a support structure provided with: a support base, intended to be fixed to the ground and, a load-bearing body, fixed to said base; at least one pair of support wheels, which are mounted on the load-bearing body of said support structure, and are free to rotate with substantially horizontal rotation axis within said rail for supporting the weight of said gate; and at least one guide wheel, which is mounted on the load-bearing body of said support structure and is free to rotate with substantially vertical rotation axis within said rail in order to oppose deviations of said gate transverse to its advancing direction; characterised in that said support structure comprises two 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 of said shaped plate being: rigidly connected to each other by means of fixing means in order to form said load-bearing body, with the two base walls oriented in opposite directions so as to form said support base to the ground; each provided with: two first openings aligned with respective corresponding first openings of the other load-bearing wall in order to jointly define two first seats adapted to house first rotatable support means of said at least one pair of support wheels; a second through opening aligned with the corresponding opening of the other load-bearing wall in order to jointly defining a second seat for receiving said guide wheel, rotatably supported by second rotatable support means.
