A system is disclosed which provides the ability to install a cross arm on a power pole utilizing an electrically isolated bucket which is free of all hydraulic components used by an operator in the bucket to manipulate the bucket. The system also utilizes an in-the-bucket rechargeable battery powered electric tool such as a saw, drill etc. without a need for a hydraulic electric generator in the bucket. The system includes the ability to provide communication to and from and to supply electrical power to remote portions of an electrically isolated boom, by transmitting optical power and control signals through an electrically non-conductive optical fiber.

A bracket has: a plate having bolt holes and a utility pole mount; a clamp secured to the plate, the clamp comprising cooperating screw pile shaft receiving parts having laterally extending flanges, the flanges having fastener receiving openings for securing the clamp around a screw pile. A combination has: a bracket; a utility pole extended from a ground surface, in which the plate is bolted to the utility pole through the bolt holes in the plate; and a screw pile fastened to the clamp and penetrating the ground surface.

System and method for monitoring the condition of electricity conductor support systems, i.e. towers, in a power network distribution system employing a tower structure integrity sensor assemblage. The system allows for identifying particular portions of a structural system for maintenance attention. The tower sensors allow identification of structural failures of electricity transmission towers.

A kit for mounting one or more appliances on a pole, the kit comprising a central ring for being mounted around a pole and having a through-hole, a fitting surface and a support surface, and a carrier having a base part and at least one support arm extending from said base part for supporting one or more appliances, wherein said base part is adapted to be fitted on said support surface and has a through-hole adapted for being fitted around said fitting surface.
