Abstract
An apparatus for placing aerial cable from a cable reel. The apparatus includes a wheeled platform having a front and rear. A boom structure having an axially extending outer end is provided and a worker's platform is mounted to the outer end of the boom structure. A boom support structure carries the boom structure and is rotatably mounted on the wheeled platform for rotation about a vertical axis. The boom structure and the boom support structure are constructed to permit the worker's platform to be moved toward and away from the wheeled platform, raised and lowered with respect to the wheeled platform and rotated with respect to the wheeled platform. A lifting apparatus is mounted on the wheeled platform for supporting a cable reel at the rear of the wheeled platform. A bullwheel assembly is mounted on the wheeled platform forward of the boom support structure for guiding cable from the cable reel. The bullwheel assembly has upper and lower sections and a mounting assembly for supporting the upper section with respect to the lower section to permit castering of the upper section with respect to the lower section. The bullwheel mounting assembly includes an actuator for elevating…
