The trolley bar for a crane, installed in a movement direction of an overhead traveling crane to apply power to the crane, comprises: a rail (110) including a pair of insertion holes (111), formed in a longitudinal direction, and a connection piece (113), formed between the insertion holes and including a combination hole (112), and having a roly poly shape; a connection terminal (130) including a female terminal (131), assembled with the insertion holes (111) of the rail (110), and a male terminal (131′), assembled with the insertion holes (111) at the other end; and a covering material (120) covering ...
