PURPOSE: A rail bar for a crane is provided to enable the stable supply of electricity by preventing a carbon collector from being separated from the rail bar even if the rail bar is bent or sagged. CONSTITUTION: A rail bar (10) for a crane is grounded with a carbon collector (40) of a current collector and supplies electricity to a crane. An insertion guide groove (32) for the carbon collector is formed on the bottom end of the rail bar. The rail bar has an upper frame (20) and a guide frame (30). The guide frame is coupled to the bottom of the upper frame. |
