Abstract
A stringing machine includes a base and an adjustable stringing platform coupled to the base. The stringing platform includes a turntable rotatable about a first axis, and a first releasable resistance assembly coupled to the turntable. The first releasable resistance assembly is selectable between an engaged operating mode in which the releasable resistance assembly resists rotation of the turntable about the first axis, and a disengaged operating mode in which the releasable resistance assembly does not resist rotation of the turntable about the first axis. The releasable resistance assembly includes a magnetorheological fluid for resisting rotation of the turntable about the first axis when in the engaged operating mode.
