Patent number: 9576708Abstract: Apparatus for replacing a suspension insulator on a tower having a davit arm supporting an attached insulator and a conductor shoe attaching an energized conductor to the insulator lower end including a non-conductive board longer than and mounted to the tower below the davit arm, struts extending between the board and the tower, and a movable slider mounted on the board, the slider supporting a jack and a conductor lifting bar attached to the jack. Without contacting any energized components, a lineman moves the slider and operates the jack to lift and support the energized components, detaches the shoe from the insulator, moves the energized components to a remote position on the board, detaches and replaces the insulator while it is supported by a helicopter, moves the slider and operates the jack to lift the shoe into alignment with the insulator and attaches the shoe to the insulator.Type: GrantFiled: April 2, 2014Date of Patent: February 21, 2017Assignee: Haverfield International IncorporatedInventor: Larry Graham

Patent number: 9478962Abstract: An electrical power line tower which is resistant to wind induced vibration damage supports vertically spaced apart electrical conductor-mounting cross arms extending from the tower, each cross arm having a mounting bracket welded to the tower end of the arm and the mounting bracket being attached to the tower via bolts. First clamping brackets on each conductor supporting arm are positioned between the tower and conductor, the first clamping brackets including cross arm-engaging bolts preventing bracket sliding along the arms and bracing poles extending diagonally upwardly between the first clamping brackets on each conductor supporting arm and a bolt securing the mounting bracket of the next higher arm along the tower. The length of the bracing poles is adjustable for providing the desired bracing support to the conductor support arms to which the bracing poles are attached.Type: GrantFiled: June 9, 2014Date of Patent: October 25, 2016Assignee: Haverfield International IncorporatedInventor: Larry Graham
