PURPOSE:To simplify constitutional members, perform miniaturization and decrease weight, in a movable bracket for supporting a trolley wire, by providing a link device, arranged liftable only for an ear holding the trolley wire, to another end of a horizontal member turnably mounted to a mast. CONSTITUTION:Each one end of a horizontal member 1 and stay member 3 is supported to a mast 2 through insulators G respectively. While a fixed member 4, consisting of amounting member 4a, cylindrical shaft 4b and hanging wiring receiver part 4c, is mounted in the other end of the horizontal member 1 by inserting through bolts 5 to the mounting member 4a and bolt holes 1a. Then a link device L, consisting of a vertical plate 6, two arms 7, 8 and rod 9, is mounted to the cylindrical shaft 4b. In this case, one side part of the vertical plate 6 is turnably supported to the cylindrical shaft 4b, further an ear E, holding a trolley wire T, is provided to a lower end of the rod 9. In this way, a movable bracket can be simplified and the supporting mast of said bracket can be miniaturized and reduced its weight. |
