Device for eliminating stresses, caused by linear actuators, on the hinges of automatically operated gates, use being made for this purpose of an arm (21) in an intermediate position between the actuator (16) and the gate (10), turning on independent hinges (20) and connected to the gate (10) by an articulation (24), and a part (23) for compensating the variations in the distance between said articulation (24) and the hinges (20) of said arm (21) during rotation of the gate (10), causing the unused component (a) of force (F), generated by the actuator (16) and substantially parallel to the gate (10), to be discharged into the hinges (20) of said intermediate arm (21), while the transversal component (b) of said force (F) acts on the gate (10) through the intermediate arm (21). |
