Abstract: Improvements in fall protection are disclosed, including a method for providing fall protection for human and non-human loads in elevated environments. The load is equipped with a safety harness and lanyard apparatus having first and second lanyards attached thereto. A method is disclosed for providing fall protection for human and non-human loads in an elevated environment wherein the load is primarily supported by an aerial lift vehicle or structure generally adjacent to a second structure.

Abstract: A fall protection lanyard apparatus for use in transferring loads in an elevated environment. The fall protection lanyard apparatus includes first and second load-bearing lanyards, each terminating in a connectable free end. Each lanyard is preferably attached to a common point, such as a load bearing steel O-ring, which in turn is attached to a safety harness which secures the load. The first lanyard incorporates a quick-release mechanism, which, upon activation, results in the separation of the hook and free end portion thereof. The second lanyard incorporates a mechanism for activating the quick-release upon application of a predetermined force thereon.

Abstract: A fall protection lanyard apparatus incorporating an automatic emergency release is disclosed. Competing concerns of fall protection (for the load) and on-demand emergency release (for the aerial lift) are each enabled by providing the first lanyard with a quick release mechanism and the second lanyard with a release triggering mechanism. The lanyard apparatus is adapted for attachment to a human or non-human load. The first lanyard incorporates a quick-release mechanism, which, upon activation, results in the separation of the connectable end portion thereof. The second lanyard incorporates a mechanism for activating the quick-release upon application of a predetermined force thereon. The lanyard apparatus provides total fall protection during the transfer of a load to a structure in any elevated environment while providing an on-demand quick-release in emergency situations.

Abstract: A fall protection lanyard apparatus for use in transferring loads in an elevated environment is disclosed. The fall protection lanyard may be connected to a load and used to safely transfer a human or nonhuman load in an elevated environment, such as from an airborne rotorcraft to an adjacent structure while providing fall protection for the load and emergency release capabilities for the aircraft. The lanyard apparatus provides total fall protection for the load throughout the transfer process without restricting or otherwise limiting available emergency flight options/maneuvers by incorporating an emergency release that automatically activates on demand. In a preferred embodiment, the fall protection lanyard apparatus includes first and second load-bearing lanyards, each terminating in a free end incorporating a connectable hook.

Abstract: Improvements in rotorcraft external load operations are disclosed, including a method for transferring a load from an airborne rotorcraft to a structure while providing fall protection for the load and emergency release capabilities for the aircraft. A helicopter is adapted for carrying a load external to the aircraft fuselage which load may be restrained by an FAA approved safety restraint. The load is equipped with a safety harness and lanyard apparatus having first and second lanyards attached thereto. According to the method, a helicopter hovers next to a structure, and safe transfer is accomplished by: (1) attaching the free end of the first lanyard to the helicopter; (2) releasing any auxiliary safety restraint; (3) attaching the free end of the second lanyard to the structure; (4) detaching the first lanyard from the helicopter; and (5) effecting transfer of the load to the structure.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
