Abstract: The locking mechanism holds a reel spindle against rotational and axial movements at all times during the loading and transport of a cable reel. Each pivoted lift arm of the reel handling apparatus is of a tubular construction and formed at its free end with a spindle receiving pocket within which the reel spindle is locked against movement by being clamped into frictional engagement with portions of the pocket. The locking member is movably supported within each lift arm and has a jaw portion retractable within an arm to open the pocket. A power unit for actuating the locking member is enclosed within an associated lift arm.
