摘要

Emergency descent system for electrical outlet pantographs, applied to electric traction vehicles powered by aerial conductors, characterized in that at the normally arched ends of the pantograph's outlet manifold, there are two trip valves, each capable of acting of them on the pneumatic descent devices, so that by laterally sliding the conductive catenary to critical extremities, said conductor contacts the corresponding tripping valve to cause the descent of the pantograph.
