ABSTRACT:
A hooked clutch for use with a crane, a hoist or the like is disclosed which includes a pair of clutching arms pivoted to a pantagraph on top of which is attached a ring. A pair of slide plates are mounted on the body of the clutch to be slidable along the body for a limited distance. The clutching arms are coupled by chain with the slide plates, which are coupled to, and uncoupled from, the ring. Simply by lifting and lowering the ring, the clutching arms can be automatically closed and opened to cause the hooks at their ends to engage, and disengage from, a member to be transported.
