Abstract
PURPOSE: To lift and let fall a spud safely and smoothly, by mounting a bell crank to a spud holder, and by strongly holding the spud to the holder by the revolution of the bell crank, in a lifting gear of the spud.
CONSTITUTION: A holder 3 is located at sufficient lower positions than a spud in order to lift the spud. The spud is located at an opening portion of a center of the holder 3. Thus, when upward pulling a rope 4 by operating a winch on the ship, an end portion of a long arm 11a of a bell crank 11 is upward pulled, and the long arm turns in the counter-clockwise direction around a pin 12. Since a short arm 11b left pulls a right-hand end of an opening portion 3a of the holder 3 through a rod 14, the holder 3 constricts the spud passing through the center and holds it. When pulling the rope 4 under this condition while drawing a rope 5, the spud is smoothly lifted.
