Abstract
The invention concerns an overhead electric traction system of the kind in which current is collected from an overhead contact wire by means of a collector carried on the roof of a vehicle and extending transversely of the contact wire. The contact wire is supported, at spaced positions along the route of the system, by an overhead structure comprising two transversely spaced upstanding members, and extending between and connected to the upstanding members, a transversely extending beam. Each of the upstanding members is so installed near its lowermost end as to permit limited pivotal movement of the member at least about an axis extending lengthwise of the route of the system and limited relative movement is permitted between the beam and the upstanding member at least about an axis extending lengthwise of the route of the system, each upstanding member being anchored to the ground by at least one tie connected to the member near its upper-most end.
