Abstract
A ratchet device for providing anti-reverse locking for a grounded slack comprises a pinwheel having flexible angled spokes circumferentially protruding therefrom and a pinion ring into which the pinwheel fits includes a plurality of angled teeth with which the angled spokes mate. The spokes flex and slide over the pinion ring teeth when the ratchet is advanced in a forward direction, and lock against the teeth when the ratchet is not being advanced.
