A portable cage and system for servicing high voltage power transmission lines, including a uniquely shaped cage lowerable onto a power line bundle of one or more conductors, the cage placeable by an ungrounded helicopter or a ground-based crane from a position above the power transmission lines lowered thereonto. Workmen may then safely move about within each basket to complete the required power line repair. The cage includes a horizontal crossframe and two baskets each connected to and downwardly hung from the crossframe, the entire cage having a unique, generally inverted "U"-shape when viewed from either end of the cage. The cage may include adjustable connector engagement wheels which contact each power line in the bundle for support and lateral movement of the cage. These wheels are connected to the crossframe such that the two basket portions of the cage hang on either side of the power line bundle, again aided by the generally inverted "U"cross-sectional shape. When wheels are included as part of the cage, brake and propulsion means are also included as part of the cage.

An arrangement and method for suspending a load from a rotary winged aircraft such as a helicopter by two releasable connections, wherein the load is adapted to be detached from the rotary winged aircraft upon both connections being released. Further safety features are also claimed.

A method and system for placing a load, which may consist of a combination of personnel, equipment and material, on or in proximity to components of an energized transmission line system. An ungrounded, overhead, aerial support means, such as a helicopter or crane, provides maneuverable support to a suspension means having dielectric strength or insulating means to minimize injurious fault current flow resulting from contact between energized and grounded components of the placement system and transmission line system. The system of ungrounded and insulated support permits contact between differing but ungrounded potentials to permit live line and barehand procedures in servicing, repairing, maintaining and constructing energized transmission line systems. A limited slip device may be used with the suspension means to provide additional length to the suspension means during movement of the supporting means, such as a helicopter, while it may be momentarily tethered to the transmission line system. A specialized retaining means may be utilized to attach the load to the suspension means.

A system for washing insulating components of high voltage and extra high voltage transmission lines. A helicopter provides an airborne, mobile, ungrounded, integrally bonded platform for a pressurized spray washing apparatus. The ungrounded helicopter hovers adjacent to the high voltage power lines to allow an articulating boom to be positioned to utilize a directed spray to pressure wash contamination from the insulators. A washing fluid tank and pump assembly contained in the helicopter provides high pressure washing fluid to the articulating boom and provides a self-contained system. Electrical bonding between the ungrounded helicopter and all wash apparatus components permits the helicopter to sustain prolonged energized contact with high voltage transmission source without incurring any adverse effect on the transmission line system, the aircraft or operators.
