Abstract
Current hoist systems often use a manual crank system with a lever arm that ratchets a rotational drum to tension a conductor. This disclosure describes systems and techniques for creating and operating a hoist system when connected and applying tension to an energized or de-energized conductor. Additionally, the systems and techniques may be applied to lifting or tensioning electrical equipment or cables that may support the conductor infrastructure. A hoist system may use a locally driven motor to apply a desired tension to a conductor or cable and may be controlled by an operator located at or away from the hoist system itself.
