摘要： A system for visually maintaining a predetermined minimum approach distance between load handling equipment and energized electrical equipment includes at least two elongate electrically insulating members that have lengths that correspond to the predetermined minimum approach distance that are mounted to at least a distal end of the load handling equipment so that they extend orthogonally outwardly from the distal end by substantially the predetermined minimum approach distance. One of the insulating members is rotatably mounted using a counterweight so as to be vertical, independent of the orientation of the load handling equipment. In use, when the distal end is in the vicinity of the energized electrical equipment, the insulating members provide visual indication that the predetermined minimum approach is being maintained and is not being encroached. A corresponding method is also described.

摘要： A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a cooperating hot-stick. The lock-out employs a clutch which prevents the translation of the clamping members relative to one another until the clutch is disengaged. The cooperating hot-stick is required for the disengagement of the clutch.

摘要： A temporary insulated conductor guard structure is mountable on an electrical insulator. The electrical insulator is mounted on the distal end of a crane or truck boom. The conductor guard structure includes a U-shaped frame having a horizontal elongate beam and a pair of stub arms upwardly extending from opposite ends of the beam. Elongate rigid, electrically conductive rollers are rotatably mounted to each of the stub arms and the beam so as to form an electrically conductive rolling surface extending around the interior of the U-shaped frame for rotationally supporting sagging electrical conductors thereon.

摘要： An apparatus for controlling tension in a pulling rope that is attached to a flying, unmanned aerial device or drone may utilize a cylinder around which the rope is wound, a shaft that longitudinally passes through the cylinder, a disc brake rotor that is mounted to the shaft, a brake caliper that is mounted circumferentially at a periphery of the disc brake rotor, and a brake lever that tensions a cable that is attached to, and movable to control movement of, the brake caliper, which may be hydraulic, against surfaces the disc brake rotor. The brake lever may be hand actuated and mounted to a handlebar. A frame may be part of the apparatus and support apparatus components and may have a protruding hitch portion that inserts into a vehicle's receiver hitch. An adjustable pulling rope guide support through which the rope is threaded, mounts to the frame.
