Abstract
A method and apparatus for permanently extending the height of an upright pole set in the ground uses pole reinforcers which are driven in the ground alongside and complemental to the pole. Extensible power devices mounted on ground-engaging supports use gripping heads mounted adjacent the upper end of the device, in such manner that actuation of the devices holds the heads in biting engagement with the pole. As the devices are extended, the heads pull the pole from the ground and through the predetermined channel formed by the pole reinforcers. Once the pole is extended to the desired elevation, the pole reinforcers are permanently secured to the pole to provide stability at the new height. The present invention is useful in moving the pole through extended displacements in a single stroke of the hydraulic cylinders of the devices, obviating the necessity for successive attachment and detachment of the apparatus during raising of the pole.
