Which type of elevator is designed specifically for casing and grips the casing with a latch mechanism?

Explanation:
Elevators designed for casing use a latch mechanism to securely grip the outer surface of the casing as it’s raised or lowered. That latch provides a positive, hands-free hold, which is essential for moving long, heavy casing joints without slipping and with safer handling. Other elevators use different gripping methods: bail type elevators rely on a bail hook to suspend tools rather than gripping the casing with a latch; slip type elevators grab the pipe with friction using slips, not a latch; and magnetic elevators lift steel pipe with magnets, which doesn’t involve a latch-based grip. So the casing elevator is the one built specifically to grip casing with a latch mechanism.
