Archimedes Claw
The claw was made to prevent ships from moving any further. It grabbed the top of the ship, bringing it into a stop. The people on board could try to remove the claw, but the firm mechanisms gripped too hard. It is named the Archimedes Claw as it is the shape of a hand.
The mechanism is a lever, like a weighing scale. Weight forced on one end of the claw would raise the other end up, it was all about timing.
