A utility pole lifting apparatus and method for raising a utility pole in addition to carried transmission cables away from a foundation, without requiring disconnecting or de-energization of the transmission cables. The utility pole lifting apparatus includes a base mounting structure configured to be coupled to the foundation and an upper lifting structure coupled to the base mounting structure and to the utility pole. The upper lifting structure is configured to elevate the utility pole above the foundation while supporting the utility pole and the transmission cables to allow an extension segment to be inserted between the foundation and the utility pole to permanently raise the height of the utility pole.

A lattice type transmission tower leveling device for leveling a transmission tower with respect to a ground surface. The tower leveling device includes a series of side supports positioned at first and second sides of the transmission tower. The leveling device also includes a support beam that is secured to a third side of a transmission tower that is leaning and a second support beam that is secured to a fourth side of the transmission tower opposite the third side. The device further includes a series of brace members that are interconnected to form a lattice brace structure. The lattice brace structure is coupled to the upright members of the transmission tower. The tower leveling device also includes a lift beam secured to the side supports of the tower and a series of hydraulic cylinders that extend from the lift beam to the first support beam. Linear movement of the cylinders causes the transmission tower to rotate about the axis of rotation so that the tower can be leveled and new tower base supports can be installed.

A utility tower lifting apparatus and method for raising a lattice tower in addition to carried transmission cables without disturbing the tower foundation, disconnecting the cables, or requiring de-energization of the transmission lines.
A lifting device that is adapted to be coupled to a pole of a utility tower and that is adapted to lift an upper portion of the pole of the utility tower to an increased height with respect to a lower portion of the pole of the utility tower to thereby increase the vertical height of the utility lower. The lifting device includes a lower lifting structure and an upper lifting structure. Upper lifting structure is movably coupled to lower lifting structure. Lower lifting structure includes a coupler adapted to be coupled to exterior surface of the pole.
