<p>Apparatus for mounting a reel of wire on a truck bed, which apparatus includes a pair of brackets mountable at opposite sides of the bed and adapted to support an elongated shaft assembly at spaced locations therealong, a shaft assembly extending between and supported by the brackets, and a friction braking assembly movably mounted on the shaft assembly for movement axially on the shaft assembly. The friction braking assembly includes a rotatable friction element adapted to be keyed to a reel rotatably supported on the shaft assembly between the brackets, a second friction element movable axially on the shaft assembly into and out of engagement with the rotatable friction element, and means for adjustably and resiliently urging the second friction element into frictional engagement with the rotatable friction element. A reel positioning plate and sleeve assembly is slidably mounted on the shaft assembly for retaining a reel in engagement with the rotatable friction element.</p> |
