Abstract: The disclosed technology includes a bullwheel assembly having a wheel configured to rotate about a central axis extending through a center of the wheel and a central hub assembly attached to the wheel proximate the center of the wheel. The central hub assembly can facilitate rotation of the wheel about the central axis. A shaft can be in mechanical communication with the central hub assembly and configured to support the central hub assembly, a bullwheel support frame in mechanical communication with the shaft and configured to support the shaft, and a plurality of removeable liners attached to the wheel and disposed along an outer circumferential surface of the wheel. Each removeable liner of the plurality of removeable liners can have a groove formed therein. The groove can be configured to receive and support various sizes of electrical utility lines.

Abstract: An intelligent electrical conductor installation system includes a puller sub-system, a tensioner sub-system, and a running board. The pull sub-system is configured to provide a pulling force to a pull rope connected on one end to the running board. The tensioner sub-system is configured to provide tension to the one or more conductors connected to the running board during installation of the conductors. The running board is connected to the pull rope on a first end, and configured to be connected to one or more conductors on a second end, wherein the running board includes one or more sensors configured to sense attributes of the conductor pull operation.

Abstract: An electrical stringing block in accordance with some example embodiments includes a sheave formed of a pair of metal plates which are joined together. Each plate includes an angled section, a planar section extending from an outer edge of the angled section, and a curved section extending from an outer edge of the planar section. The plates are joined together at the planar sections. Each angled section is continuous.

Abstract: A crossarm bracket suitable for use with crossarms constructed of various materials, including wood, fiberglass or other similarly-constructed composite crossarms. In some embodiments, the crossarm bracket comprises a top bracket comprising a first attachment point and a second attachment point and at least one flexible compression member having a first attachment end for attaching a first end of the at least one flexible compression member to the first attachment point and a second attachment end for attaching a second end of the at least one flexible compression member to the second attachment point, thereby attaching the at least one flexible compression member to the top bracket. In some embodiments, the crossarm bracket further comprises a flexible compression member tightening mechanism, such as a come along, to secure the top bracket to the crossarm.

Abstract: A vehicle mounted automobile "wheel lift" towing mechanism having a power actuated lift boom vertically movable between raised and lowered positions along angularly inclined parallel tracks having cam members operable to impart predetermined vertical tilting movements to the boom; the latter at ground engagement being tiltable to conform to variations in ground slope; power actuation of the boom being responsive to extension and contraction of a horizontal lift cylinder assembly having a linearly movable piston. Manually operable wheel engaging apparatus, is carried by the lift boom for positively coupling a pair of vehicle wheels to the towing mechanism and includes a pair of pivotally movable wheel restraints operable to swing arcuately about vertical axes from positions laterally outwardly of adjacently opposed vehicle wheels to positions behind such wheels for restraining the latter against opposing wheel chocks.

Abstract: This invention provides a device enabling movement of an electrical conductor through, or from one side to the other of, a string of insulators coupled between a supporting tower and a yoke plate, and has an upper frame with clamping jaws engageable with one of the insulators, a lower frame connectable to the yoke plate, and manually operable mechanism interconnecting the two frames for selectively moving them relative to each other in the direction of the axis of the insulator string to permit uncoupling of a portion of the string, movement therethrough of the conductor, and recoupling of the string.

Abstract: A method of stringing a bundle of cables from a suspension bracket suspended from a tower cross arm by insulator strings includes securing a temporary connection along at least a part of one of the strings to provide a temporary suspension connection which enables the string to be uncoupled, so that one of the cables can be passed through the uncoupled string. The string is then recoupled and the temporary connection is removed to allow the conductor to be secured to the suspension bracket. This method enables one or more cables to be secured above the suspension bracket for reducing the voltage gradient across the lowermost insulators of the strings.

Abstract: A transformer caddie comprises: an inverted U-shaped frame having a horizontal top portion and front and rear vertical support means; transformer hoist means mounted substantially at the center of the top portion and being operable to suspend a transformer therebelow; front and rear wheels, preferably comprising front and rear pairs of adjacently disposed wheels; plural wheel mounting bracket means, each being rotatably connected to an associated vertical support means to mount one of the wheels for revolution about a horizontal axis, and also for steering about a steering axis; and steering means for rotating the wheel mounting bracket means to effect steering of the caddie, the steering means preferably comprising independently operable front and rear steering means, each being operable to effect tandem steering of both of an associated pair of wheels. The caddie is operable to efficiently transport and locate transformers and other electrical equipment in inaccessible areas.
