Abstract
Disclosed embodiments provide a cross-arm phase-lifter for lifting and maneuvering a utility pole cross-arm without the need to remove the energized power lines from the cross-arm. A first embodiment of the cross-arm phase-lifter may comprise a set of clamps, clamping members, and actuators. When the actuators are driven, the clamping members may secure the clamps onto the cross-arm. Once the clamps are secured, the cross-arm may be lifted and suspended in air. A second embodiment may comprise a lifting plate comprising a plurality of pegs configured to interface with brackets on the cross-arm. When the pegs are engaged with the brackets, the cross-arm may be lifted and suspended in air.
