<p>A reel carrier support assembly is mounted on the push beams of a bulldozer to enable simultaneous reel dispensing and bulldozing. The support assembly includes a rotatable beam located above the bulldozing blade and having a pair of spaced arms projecting forwardly of the blade to support a cable reel. The rotatable beam is supported by a pair of support arms, which in a first preferred embodiment are rigidly mounted to the push beams and in a second preferred embodiment are pivotally mounted to the push beams. In the first embodiment, the support arms are spaced from the blade sufficiently to avoid interfering with blade tilting movement. In the second embodiment the pivotal connection accomodates upward pivotal movement of the reel carrier during blade tilting movement. A further preferred embodiment includes a hydraulic piston and cylinder for manipulating the rotatable beam.</p> |
