A slip ring structure of a crane is provided to achieve stable connection by making surface contact between a slip ring and a brush so as to minimize the wear of the brush and the slip ring. A slip ring structure of a crane comprises a slip ring(10) and a brush(20). The slip ring is fixed to a fixed axis(1a) of a fixed body(1) which is set at a certain height on the ground. The slip ring comprises a first contact surface(11) having a plane on the outer periphery. The brush is mounted on a rotating part(2a) of a rotary body(2). The brush comprises a second contact surface(21) having a plane connected to the first flat contact surface of the slip ring. |
