Abstract A method and apparatus for lengthening or shortening a pole supporting lines, such as electric power and telephone lines. The method includes the providing of a stub adapted to be joined in abutting end-to-end relationship with the lower end of the pole to form a lower extension and support for the pole. The pole is raised vertically until its lowermost end portion is clear of the ground so that a lower end portion of the pole can be sized, as necessary, for reception by a mechanism joining the pole and stub. If necessary, the length of the pole is also shortened to provide a desired combined length. After the lower end has been sized, the pole and stub are joined to each other so that they constitute, in effect, a substantially rigid continuation of each other. The pole and stub are then vertically lowered into the ground to a required depth and the ground is consolidated around the base of the stub. The apparatus includes appropriate structure for accomplishing the preceding method.
An apparatus for repairing a pole used to support a line comprising: a base frame; guide means carried by said base frame positionable in a substantially vertical position adjacent a pole to be repaired; a movable carriage guided by said guide means; clamp means carried by said carriage for clamping the pole; means for moving said carriage with respect to said base frame so that the clamped pole is raised and lowered with respect to the base frame; and cutting means carried by said base frame for sizing a lower end portion of a raised pole.
