A brake assembly employing a plurality of upper and lower friction sheaves having edge aligned overlapping relationship for frictionally gripping a conductor therebetween. A fair-lead housing is mounted on the infeed end of the brake assembly and employs a horizontal axis guide roller with which the conductor is in engagement forward of the infeed end for feeding to the brake assembly. The guide roller is supported for a combined vertical and longitudinal adjustment relative to the infeed end of the brake assembly for varying the angle at which the conductor engages the first friction sheave in the brake means. Such roller is supported on a hinged carrier capable of being swung outwardly, whereby to displace the roller from the housing for the purpose of laying a conductor flatwise into the fair-lead housing for subsequent engagement with the brake means. The fair-lead housing also has at least one pair of upright rollers providing longitudinal guiding of the conductor through the fair-lead housing, and a top opening is provided in the housing between these rollers so that a conductor can be laid flatwise in the housing. Hinged plate means engage the upper end of the upright guide rollers in one position thereof to connect them to the fair-lead housing and in another position to be out of the plane of the top opening. The fair-lead housing and other conductor engaging means therein are formed of electrically conductive material and are arranged to be connected to a ground line for electrically grounding the conductor.
