Abstract

PURPOSE: To prevent positively, a steady rest from collision with a pantagraph in a trolley line of catenary suspension by lifting this steady rest upward with a coiled spring when the steady rest getts out of the trolley line.
CONSTITUTION: When a pantagraph comes to an engaging point of a trolley line 4 and a steady rest 14, it is abruptly pushed up. However, since the engaging point is urged upward by a coiled spring 15 to be somewhat hung up, the pantagraph slides smoothly without abrupt increase of contact force. Also, if the pantagraph would get out of the trolley line due to any causes, the steady rest 14 is lifted up by the upward-urging force of the coiled spring 15 to be located outside passage of the pantagraph. Thus, current is collected smoothly and positively, and the pantagraph and line can be prevented from breakage even in disengagement of the pantagraph with the trolley line.
