Abstract
The invention relates to a conductor rail having at least one expansion joint between rigid section bars and presenting a friction shoe with a conductive guidance and friction path. In accordance with the invention, the free ends of the section bars have respective systems of interfitting parallel plates suitable for providing an expansion joint which ensures guidance continuity and electrical pickup continuity regardless of the relative longitudinal position of the section bars. Such conductive rails may be used to feed electricity to handling equipment such as cranes, travelling cranes, and container lifters.
