A device for pulling a cable down the length of a cable tray including a trolley with rollers which rollingly grasp the upper side portion of the cable tray and allow the trolley to roll along the tray. The trolley includes a swivel cord grip which is releasably attached to one end of the cable, thus allowing the cable puller to pull the cable along the cable tray as the cable puller is propelled along the cable tray. The trolley can be pulled along manually by using one of two pull lines or ‘jet lines’ which are attached to the cable puller and lead to each end of the cable tray, or, more preferably, the trolley can be propelled up or down the cable tray by a remotely controlled motor which drives one or more of the rollers.

The disclosure relates to the field of electric power infrastructure and repurposing existing oil and gas pipeline, or other pipelines which are no longer in use for their original purpose, for installation of conduits and electrical cables/conduits, typically underground, for electric power transmission.

Cables, such as telecommunications cables, fiber cables, conduits, and the like, can be installed in existing pipe systems to avoid the need for trenches. However, to aid in keeping the cables out of the flow of the pipes of the pipe system, the cable or cables are positioned adjacent a wall of the pipe. To hold or otherwise secure the cables in place, aspects of CIPP pipe repair are used in place of mechanical fasteners. This can take many forms, including, but not limited to, curable resins, resin impregnated liners or liner straps, T-liners, gaskets, etc. The resin or resinous liners can be inflated towards the wall of the pipe to hold the cables in place between the curable resin and the wall of the pipe.

A rodder assembly to be moved through an underground conduit includes a tube adapted to receive fluid under pressure. In some embodiments the rodder assembly includes at least one rigid rod, and a nozzle is attached to the tube to discharge fluid from the tube.

A wiring apparatus for a communication pipeline includes a frame and wheels arranged on the frame in pairs. A control motor for driving the wheels to rotate is arranged on the frame, at least one pair of wheels are rotatably connected to the frame, a recessed wire clamping cavity is arranged on an outer peripheral of the wheel, a channel configured for clamping an optical power cable is formed between two wheels arranged in pairs through the wire clamping cavity, and a hook (on which a wiring can be hung) is arranged at an end of the frame.

A headlock cable installation system includes a headlock assembly, an extension rod, and a flexible headlock cable. The headlock cable installation system is used for installing a pre-connectorized cable assembly. The headlock assembly defines a cavity configured to receive a connectorized end of the pre-connectorized cable assembly. The flexible headlock cable has opposite first and second ends. The first end of the headlock cable is coupled to the headlock assembly, whereas the opposite second end of the headlock cable is adjustably coupled to the extension rod. Adjustment of the second end varies a position of the headlock assembly relative to the extension rod.

A draw wire apparatus, including: a rod and a motor for rotating the rod; a thread extending from the rod, for being attached to a draw wire, and shaped for advancing thereof upon the rotation of the rod; and an oil pump characterized in being operated by the rotation of the rod, and disposed adjacent to the draw wire, thereby drawing oil onto, thereby the motor lubricates the draw wire and as well advances thereof.

A cable rod guiding device including a housing assembly, an arm assembly, a camera assembly, and a control assembly. The cable rod guiding device is mounted to a cable rod to be maneuvered within an obstructed space. The housing assembly includes a housing having a first portion and a second portion. The control assembly includes a motor housed in the second portion to control an articulating arm of the arm assembly. The camera assembly includes a camera to provide a view of the obstructed space to detect and overcome obstructions along the obstructed space through which the cable rod guiding device is maneuvered through. Upon the detection of an obstruction, the obstruction is avoided or overcome through the usage of the articulating arm being controlled by a user and the control assembly. Allowing the user to safety, efficiently, and effectively pass cable through the obstructed space with minimal effort.
