PROBLEM TO BE SOLVED: To provide a hanger ear which does not damage a trolley wire during the attachment, which is easily constructed even at an unsteady high place, and can uniformly grasp the trolley wire without looseness by large elastic force.SOLUTION: In a hanger ear 1, shapes of two ear pieces 3, 4 have the structure symmetrical with respect to a surface orthogonal to an axis of a trolley wire T, and connection parts 31, 41 at an upper part are integrally fastened to a hanger bar 2 with a compression ring 5. When a wedge pin 6 is driven in, imbalance of the grasp force does not occur at a grasp part 44 in an axial direction of the trolley wire T, and the trolley wire T is grasped with uniform force. Strong elasticity of the ear pieces 3, 4 themselves is added to the grasp force, thus looseness is less likely to occur over time. Attachment work is completed by disposing the trolley wire T between the grasp parts 34, 44 and driving in the wedge pin 6 built-in in advance.
【課題】装着時にトロリ線を傷つけず、不安定な高所でも施工容易であり、大きな弾性力で緩みなくトロリ線を均一に把持できるハンガイヤを提供する。【解決手段】ハンガイヤ1は、2つのイヤ片3,4の形状が、トロリ線Tの軸線直交面に対して対称の構造であり、上部の接続部41が圧縮リング5で一体にハンガバー2に固着される。クサビピン6を打ち込む際に、把持部44におけるトロリ線Tの軸線方向に把持力の偏りが生じず、トロリ線Tを均一の力で把持する。把持力には、イヤ片3,4自体の強い弾力が加わるので、経時による緩みが生じにくい。把持部44間にトロリ線Tを配置して、予め組み込まれているクサビピン6を打ち込むことにより装着作業が完了する。【選択図】図3
