Abstract
A method and apparatus for removing ice from overhead utility power lines which includes a tool having an extendable pole with an ice removing roller having an annular outer channel rotatably supported on the pole. The pole is extendable for enabling a user to place the roller over an ice-laden utility power line while standing on the ground, and then is movable along the power line by the workmen while standing on the ground or walking along a line parallel to the power line for removing ice from the line.
Claims1
A method of removing ice from utility power lines supported at an elevation above the ground comprising the steps of providing a tool having an extendable pole made of electrically non-conductive material for withstanding power voltage up to 100,000 volts with an ice removing roller with an outer annular channel rotatably supported at an end of the extendable pole, manually extending the pole from a retracted position to an extended position having a length sufficient for placing the roller onto and over an ice-laden line by a user standing on the ground holding the pole, rolling the roller over the ice-laden line to dislodge ice from the power line by a user walking on the ground below the power line in a direction generally parallel to the power line while holding the pole at an angle to the power line so that the roller is not directly overhead of the user, and forcing the roller against the power line and ice thereon by (1) allowing the weight of the tool to hang from the power line and (2) manually pulling the pole in a downward direction by the user with sufficient additional force as to effect dislodgement and removal of ice from the power line.
