摘要：
A rachet pawl (22) for a hoist (10) is self-camming into engagement with a ratchet wheel (20) of the hoist. The pawl includes a primary lobe (32) which engages the ratchet wheel teeth (24) and a secondary lobe (34) which rides on the ratchet wheel teeth to cam the primary lobe into position to engage the next ratchet wheel tooth. In a preferred embodment, the primary lobe is also spring biased into position to engage the ratchet wheel teeth.
