ABSTRACT:
A cable coating apparatus comprising a container mounted on a pole; two trolley wheels mounted within the container at an upper portion thereof for engagement with a supportive wire that supports a cable by spaced connectors, and nozzles mounted within the container pointed at the cable. Pivotably mounted within lower portion of the container is an upwardly spring biased lever arm with a roller mounted thereon in abutment with the underside of the cable. Two nozzles are mounted at the free end of the lever arm pointing upwardly to the cable. Two more nozzles are movably mounted at an upper portion of the container pointing downwardly to the cable. The supply conduit operably connects the nozzles to a supply tank and pump. A vertical shaft pivotally couples the lever arm to the top nozzles such that when the roller rolls along the cable and moves up and down due to the variations in the relative height of the cable, the bottom and top nozzles correspondingly move to maintain a predetermined distance with respect to the cable. The container retains excess and divergent spray from the nozzles and has a drain at the bottom portion thereof to recycle the spray back through the nozzles.
