摘要： A set of components for assembling a temporary wire suspender includes in the set a yoke plate, a plurality of J-hook assemblies, a plurality of linkage members, and a plurality of removable couplers configurable to handle an expandable number of energized or de-energized conductors or sub-conductors. Positive control of the suspended and/or supported energized or de-energized conductors or sub-conductors is achieved by using releasable latches on the J-hook assemblies.

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.

摘要： A conductor lifter adapted to be mounted to a tower for temporarily supporting an energized conductor comprises a support arm having a base end and an opposite cantilevered end and a crank arm pivotally mounted on the cantilevered end, the crank arm having lower and upper crank arms. A first actuator is coupled to the support arm, and an elongate member is mounted to, so as to extend between, the upper crank arm and a first driver of the first actuator so as to rotate the crank arm about the pivotal coupling when the first actuator is actuated. A lower end of the lower crank arm is selectively elevatable by a second actuator relative to the upper crank arm so as to elevate a conductor when held by a conductor retainer on an insulator mounted to the lower crank arm. A method for using the conductor lifter is also provided.
