Abstract
Apparatus for installing communication and power cables in tunnels includes a base member adapted for longitudinal transport through a tunnel on a railroad flatbed that rotatably supports a cable supply reel. A cable guide arm is connected at one end with the base member for pivotal displacement about a horizontal pivot axis parallel with the base member longitudinal axis, and a cable guide pulley is connected with the other end of the guide arm for guiding a cable supplied by the reel to a desired point of installation on the tunnel wall. A length-adjusting arrangement adjusts the length of the guide arm to correspond with the width of the tunnel, and an angle-adjusting arrangement adjusts the angle of the guide arm relative to the horizontal surface of the base member. The base member is mounted on a sled for lateral displacement transversely of the flatbed.
