A sectionalized crane collector system is provided for electrical power rail systems for overhead cranes and the like made up of a pair of aligned conductor rails spaced apart longitudinally to form an air gap and having upper surfaces for engagement by a current conductor movable along them, a bridging rail member of the same shape as the air gap and adapted to fit in the air gap flush with the top of the conductor rails, a conductor apparatus fixed to and parallel to the bridging rail and in electrical contact therewith, the conductor apparatus being longer than the air gap, resilient conductor apparatus on each aligned conductor rail adjacent the air gap releasably engaging the ends of the parallel conductor member, vertically movable carrier apparatus adjacent said air gap carrying the parallel conductor means between a first position engaging the resilient conductor apparatus in which the bridging rail member fills the air gap flush with the top of the aligned rails and a second position in which the parallel conductor apparatus is out of engagement with the resilient conductor apparatus and the bridging rail member is removed from the air gap, and drive apparatus acting on said carrier apparatus to move it selectively between said first and second position.
